OWB bugs, missing functionality and the future of OWB

I'm working with OWB for some time now and there are a lot of rough edges to discover. Functionality and stability leave a lot to be desired. Here's a small and incomplete list of things that annoy me:
Some annoying OWB bugs (OWB 10g 10.1.0.2.0):
- The debugger doesn't display the output parameters of procedures called in pre-mapping processes (displays nothing, treats values as NULL). The mapping itself works fine though.
- When calling selfmade functions within an expression OWB precedes the function call with a constant "Functions." which prevents the function from being executed and results in an error message
- Occasionally OWB cannot open mappings and displays an error message (null pointer exception). In this case the mapping cannot be opened anymore.
- Occasionally when executing mappings OWB doesn't remember changes in mappings even when the changes were committed and deployed
- When using aggregators in mappings OWB scrambles the order of the output attributes
- The deployment of mappings sometimes doesn't work. After n retries it works without having changed anything in the mapping
- When recreating an external table directly after dropping the table OWB recreates the external table but always displays both an error message and a success message.
- In Key Lookups the screen always gets garbled when selecting an attribute as a join condition
- Usage of constants results in aborts in the debugger
- When you reconcile a table used in a key lookup the lookup condition sometimes changes. OWB seems to remember only the position of the lookup condition attribute but not the name.
- In the process of validating a mapping often changes in the mapping get lost and errors occur like 'Internal Errors' or 'Null Pointer Exceptions'.
- When you save the definition of external tables OWB always adds 2 whitespace columns to the beginning of all the lines following 'ORGANISATION EXTERNAL'. If you save a lot of external table definitions you get files with hundreds of leading whitespaces.
Poor or missing functionality:
- No logging on the level of single records possible. I'd like the possibility to see the status of each single record in each operator like using 'verbose data' in PowerCenter
- The order of the attributes cannot be changed. This really pisses me off expecially if operators like the aggregator scramble the order of attributes.
- No variables in expressions possible
- Almost unusable lookup functionality (no cascading lookups, no lookup overrides, no unconnected lookups, only equal condition in key lookups)
- No SQL overrides in soruces possible
- No mapplets, shared containers or any kind a reusable transformations
- No overview functionality for mappings. Often it's very hard to find a leftover operator in a big mapping.
- No copy function for attributes
- Printing functionality is completely useless
- No documentation functionality for mappings (reports)
- Debugger itself needs debugging
- It's very difficult to mark connections between attributes of different operations. It's almost impossible to mark a group of connections without marking connections you don't want to mark.
I really wonder which of the above bugs and mssing functionality 'Paris' will address. From what I read about 'Paris' not many if at all. If Oracle really wants to be a competitor (with regard to functionality) to Informatica, IBM/Ascential etc. they have a whole lot of work to do or purchase Informatica or another of the leading etl tool
vendors.
What do you think about OWB? Will it be a competitor for the leading etl tools or just a cheap database add on and become widely used like SAB BW not for reasons of technology or functionality but because it's cheap?
Looking forward to your opinions.
Jörg Menker

Thanks to you two for entertaining my thoughts so far. Let me respond to you latest comments.
Okay, lets not argue which one is better.. when a tool is there .. then there are some reasons to be there...But the points raised by Jorg and me are really very annoying. Overall I agree with both yours and Jorg's points (and I did not think it was an argument...merely sharing our observations with each other (;^)
The OWB tool is not as mature as Informatica. However, Informatica has no foothold in the database engine itself and as I mentioned earlier, is still "on the outside looking in..." The efficiency and power of set-based activity versus row-based activity is substantial.
Looking at it from another way lets take a look at Microstrategy as a way of observing a technical strategy for product development. Microstrategy focused on the internals (the engine) and developed it into the "heavy-lifting" tool in the industry. It did this primarily by leveraging the power of the backend...the database and the hosting server. For sheer brute force, it was champion of the day. It was less concerned with the pretty presentation and more concerned with getting the data out of the back-end so the user didn't have to sit there for a day and wait. Now they have begun to focus on the presentation part.
Likewise this seems to be the strategy that Oracle has used for OWB. It is designed around the database engine and leverages the power of the database to do its work. Informatica (probably because it needs to be all things to all people) has tended to view the technical offerings of the database engine as a secondary consideration in its architectural approach and has probably been forced to do so more now that Oracle has put themselves in direct competition with Informatica. To do otherwise would make their product too complex to maintain and more vendor-specific.
I am into the third data warehousing/data migration project and my previous two have been on Informatica (3 years on it).I respect your experience and your opinions...you are not a first timer. The tasks we have both had to solve and how we solved them with these tools are not necessarily the same. Could be similar in instances; could be quite different.
So the general tendency is to evaluate the tool and try to see how things that were needed to be done in my previous projects can be done with this tool. I am afraid to say .. I am still not sure how these can be implemented in OWB. The points raised by us are probably the fall out of this deficiency.One observation that I would make is that in my experience, calls to the procedural language in the database engine have tended to perform very poorly with Informatica. Informatica's scripting language is week. Therefore, if you do not have direct usability of a good, strong procedural language to tackle some complicated tasks, then you will be in a pickle when the solution is not well suited to a relational-based approach. Informatica wants you to do most things outside of the database (in the map primarily). It is how you implement the transformation logic. OWB is built entirely around the relational, procedural, and ETL components in the Oracle database engine. That is what the tool is all about.
If cost is the major factor for deciding a tool then OWB stands far ahead...Depends entirely on the client and the situation. I have implemented solutions for large companies and small companies. I don't use a table saw to cut cake and I don't use a pin knife to fall trees. Right tool for the right job.
...thats what most managers do .. without even looking how in turn by selecting such a tool they make the life tough for the developers.Been there many times. Few non-technical managers understand the process of tool evaluation and selection and the value a good process adds to the project. Nor do they understand the implications of making a bad choice (cost, productivity, maintainability).
The functionality of OWB stands way below Informatica.If you are primarily a GUI-based implementer that is true. However, I have often found that when I have been brought in to fix performance problems with Informatica implementations that the primary problem is usually with the way that the developer implemented it. Too often I have found that the developer understands how to implement logic in the GUI component (the Designer/Maps and Sessions) with a complete lack of understanding of how all this activity will impact load performance (they don't understand how the database engine works.) For example, a strong feature in Informatica is the ability to override the default SQL statement generated by Informatica. This was a smart design decision on Informatica's part. I have frequently had to go into the "code" and fix bad joins, split up complex operations, and rip out convoluted logic to get the maps to perform within a reasonable load window. Too often these developers are only viewing the problem through the "window" of the tool. They are not stepping back and look at the problem in the context of the overall architecture. In part Informatica forces them to do this. Another possible factor is they probably don't know better.
"One tool...one solution"
Microstrategy until recently had been suffering from that same condition of not allowing the developer to create the actual query). OWB engineers need to rethink their strategy on overriding the SQL.
The functionality of OWB stands way below Informatica.In some ways yes. If you do a head-to-head comparison of the GUI then yes. In other ways OWB is better (Informatica does not measure up when you compare it with all of the architectural features that the Oracle database engine offers). They need to fix the bugs and annoyances though.
.. but even the GUI of Informatica is better than OWB and gives the developer some satisfaction of working in it.Believe me I feel your pain. On the other hand, I have suffered from Informatica bugs. Ever do a port from one database eingine to another just to have it convert everything into multi-byte? Ever have it re-define your maps to parallel processing threads when you didn't ask it to?
Looking at the technical side of things I can give you one fine example ... there is no function in Oracle doing to_integer (to_number is there) but Informatica does that ... Hmm-m-m...sorry, I don't get the point.
The style of ETL approach of Informatica is far more appealing.I find it unnecessarily over-engineered.
OWB has two advantages : It is basically free of cost and it has a big brother in Oracle.
It is basically free of cost...When you are another "Microsoft", you can throw your weight around. The message for Informatica is "don't bite the hand that feeds you." Bad decisions at the top.

Dan Phillips

I would like to put Dreamweaver 8 on a new computer. There is no "deactivate" function and the technical support person I chatted with recommended I come here. Can I just use the serial number again? How can I deactive? Has anyone else run into this?

There is no "deactivate" function and the technical support person I chatted with recommended I come here. Can I just use the serial number again? How can I deactive? Has anyone else run into this? How can I get Dreamweaver 8, which is no longer being activated by Adobe, on a new computer? Is it even worth doing or do I need to get a new version. What are the killer features I'm missing?

If you manage to get it installed on your current OS, don't forget to install the 8.02 update.

Since installing LTR 5.4, which I've now upgraded to 5.6, I've encountered repeated slowness and malfunctions in operations, especially when using the Compare View function and the Tab key to open and close the right and left side panels. Such problems never arose during two years of using LTR-4 and nothing else has changed on my computer. I have a pretty simple system with only a few plug-ins, which are usually not in operation. I have 12GB of RAM in my Windows 7 PC. I could illustrate these problems with screen shots if you would tell me how to submit screen shots. Otherwise I will try to describe the problems in words.
The problem is clearly cumulative, growing worse as usage time passes. Compare View feature gradually slows down and eventually seems to choke as my work session proceeds. If I Exit LTR and re-enter and start all over, things will work normally for maybe 30 minutes, but then the Compare View feature begins to become very slow to respond. In a recent example with my screen full of thumbnails in Library mode I highlighted two images to compare. LTR started to open the Compare View screen by first having the top row of thumbnails disappear to be replaced by the "SELECT" and "CANDIDATE" words in their spaces (but no images), but Compare View never succeeded in gaining control of the screen. After some seconds the top row of thumbnails reasserted its position and the Compare View windows disappeared. But LTR kept trying to bring them back. Again the top row of thumbnails would go away, Select and candidate would reappear, try again, and give up. This went on for at least 2-3 minutes before I tried to choose File and Exit, but even that did not initially want to respond. It doesn't like to accept other commands when it's trying to open Compare View. Finally it allowed me to exit.
To experiment I created a new catalog of 1100 images. After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data. (I have a screen shot to show this.) CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong. I could also send screen shots of this data.
At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR. This is not normal. I hope you can find the cause, and then the solution. If you would like to see my screen shots, tell me how to submit them.

HT1218 After a recent iTunes update attempt iTunes no longer functions and the airport extreme base station is not accessable on our computer. We still have wifi but cannot access the base station software.

After a recent iTunes update attempt iTunes no longer functions and the airport extreme base station is not accessable on our computer. We still have wifi but cannot access the base station software.

Thanks for the reply. I appreciate the response. I tried that approach this evening and it didn't work for me. (Technically it worked for me, when I was hardwired into my base station, but would not work for me wirelessly, which is my main issue.)
Again, using the approach you recommended works only if I have my ethernet cable attached to the LAN port so my computer is communicating directly to the base station through the hard wire. I am able to scan for my base station and make setting adjustments normally this way too.
As soon as I disconnect from the LAN port and try to go wireless is where I run into problems. The Base Station's wireless network I created is available to choose in the top right corner of the monitor with all of the other available wireless devices/networks -- but the network I created does not have access to the internet. I am also unable to configure my Base Station wirelessly. When my Airport Utility tries to scan for the Base Station and Network, it cannot find any Apple Wireless Device. It's like the Wireless Network in my base station is not sending out a signal.
Is there a way to resolve this issue?

I don't know how to use the canlendars function and the notes are kind of messy code,anyone help me

i don't know how to use the canlendars function and the notes are kind of messy code,anyone help me

Step by step:
1. On your main vi Front Panel, create your boolean indicator.
2. On the block diagram, right click the new boolean indicator and select Create - Reference.
3. On sub-vi front panel, create boolean indicator (or use one that is already created).
4. On sub-vi front panel, create a reference (Controls Palette - Refnum - Control Refnum).
5. Right click on the newly created Refnum and select Select Vi Server Class - Generic - GObject - Control - Boolean. The refnum label changes to BoolRefnum.
6. On sub-vi block diagram, create Property Node (Functions - Application Control - Property Node). Find the BoolRefnum and move it close to the new Property Node.
7. Wire the BoolRefnum to the reference input of the property node.
8.
Right click on the property node and select Change to All Write.
9. Move mouse to point to Visible inside property node box, left click and select Value.
10. Wire the boolean indicator from step 3 to the Value input of the property node.
11. On sub-vi front panel, right click on icon and select Show Connector.
12. Click on empty connector spot then click on the new BoolRefnum. Save your sub-vi.
13. On main vi block diagram, connect refernece created in step 2 to the new connector terminal of sub-vi.
14. Save and run.
Here are the modified vi's.

A bug in /etc/rc.d/functions; and the release policy

This is a small issue, but how it relates to Arch's release policy is important.
I have CONSOLE="ter-120b" in my rc.conf, and I got following screen on startup. The message about console font is overwritten by the next message. Additionally, the right side is "[BUSY]".
http://i795.photobucket.com/albums/yy24 … ot/bad.png
It turned out to be a bug in the set_consolefont, in /etc/rc.d/functions:
if (($? != 0)); then
stat_fail
elif [[ $CONSOLEMAP ]]; then
cat <<"EOF" >>/etc/profile.d/locale.sh
if [ "$CONSOLE" = "" -a "$TERM" = "linux" -a -t 1 ]; then printf "\033(K"; fi
EOF
stat_done
fi
stat_done is not called on the implicit "else" branch. The fix is easy:
if (($? != 0)); then
stat_fail
else
if [[ $CONSOLEMAP ]]; then
cat <<"EOF" >>/etc/profile.d/locale.sh
if [ "$CONSOLE" = "" -a "$TERM" = "linux" -a -t 1 ]; then printf "\033(K"; fi
EOF
fi
stat_done
fi
The effect is shown here.
http://i795.photobucket.com/albums/yy24 … t/good.png
However, that made me think about Arch's release policy. The latest release is 2010.5, 10 months ago. That usually doesn't matter that much, as Arch is a rolling release distro, and the CD image is really light. However, now and then we may spot bugs in scripts like /etc/rc.d/functions, which come with the CD and remain untouched by pacman. Will it be better if we follow Gentoo's approach, generating installation media every few days, putting latest software (and more importantly for Arch) and fixed scripts in it?
PS. I'd love to remove some black area in the screenshots, but I can't figure out how to do it with GIMP. Help on this is also appreciated.

You are mistaken. /etc/rc.d/functions is provided by the initscripts package, which has been updated four times since the 2010.05 release. The current version is 2011.02.1.
I suggest you submit the bug and your patch in the normal way, so that it is handled correctly.
All right, so I'm firing a bug report and send in my patch there. I have also found that /etc/rc.d/functions has some style problems. It uses a mix of space and tab for indentation, and the misleading modeline option "ts=2" (ts means "tabstop") makes the code look terrible. I have tried several values, and ts=8 turned out fine(most likely the author use this setting and don't use vim). The code is still inconsistent in style, though. So I'm going to clean up the style too. Is that okay as long as I don't break something?

ColdFusion and The Future

Admittedly, I've been a bit out of touch ... however I was
wondering what the future of ColdFusion is regarding Adobe... have
they made any announcements about the future of ColdFusion? How
will it compete with formats such as PHP/mySQL in the future? Being
a long time fan of Cold fusion, I'm curious about this.

>> 2. Image manipulation functionality -- provides both
high-level tag
based abstractions for common tasks like resizing, cropping,
and
format conversions
That so slack how CF still doesn't have this functionality
already - lets
hope its not too late to make a difference. Nice feature
though, sounds like
it may be quite sophisticated.
All in all though, based on what has been revealed here, it
doesn't sound
like much of an update - would still like to see some higher
level
framwework stuff, or maybe even a ColdFusion IDE (Heck, how
can they sell
this product at this price and not even offer an IDE for it?)
Lets hope the future reveals something a little more exciting
than what was
mentioned here.

Portal and the Future.

We are under going a major re-development effort on our internal and external sites. Part of the project will be using portal.
We are planning the Portal part prototype on 1.0.2.2 but are a little concerned about the future changes of portal. We assume that the portal will have an upgrade script but we are worried more on the provider classes. Are they going to remain the same? Should we develop now or wait for the new version? Will it give us added access to the portal API to allow for addition functionality?
Thanks,

In iAS v9.0.2 (the next release of iAS), there will be 2 versions of the JPDK API - version 1 and version 2.
Version 1 is virtually identical to JPDK 3.0.9 (no API changes), with some additional functionality for supporting mobile devices. Version 1 will be supported as long as Oracle Portal release 3.0.x is supported.
Version 2 has some API changes and the packages have been re-organized. If you use the DefaultProvider and DefaultPortlet classes currently, the changes to you code will mainly be changes to import statements to reflect the new package structure. If you implement the Provider & Portlet interfaces or extend DefaultProvider/DefaultPortlet, you will have some additional code changes, but the changes are relatively simple.
In addition, most of the interfaces have been replaced by abstract classes.
These changes were made in the interest of future stability - allowing the API to be extended without breaking existing implementations.

I just upgraded my iPhone to IOS 7.1 and not the speech to text function and the Siri function doesn't work. I tried rebooting but that didn't help

I just upgraded my IPhone to IOS 7.1 and now the speech to text function and Siri doesn't work
The microphone icon is white not grey
And when I hit it it only stays on for a split second
Not long enough to dictate a message
It worked fine before upgrade
And works on IPad which I also just upgraded
Help??

There are many, many threads on this forum about this issue. Do a forum search for "wi-fi greyed out" and see if any of the solutions therein will work for you. Best of luck.

Photo Organization and the Future

Here's my concern - utilizing aperture to organize my projects and albums, departing from managing the file structure (which is getting impossible to keep up with) I have to assume that Apple and Aperture will always be around.
What if in the future I want to switch to Light Room, or go back to windows? I have nearly 35,000 photo's now, and I imagine I'll have more in 50 years but I have no idea if Aperture will still be around in 50 years and If I stop paying attention to my file structure, I'll lose all the organization behind my masters.
Aren't any of you concerned about the distant future? Apple could pull the plug on Aperture; somebody else could come out with somethign better; etc.

No, I'm not concerned about my file structure. The fact that Aperture takes care of that for Managed libraries doesn't mean that there is no structure. The library normally resides in the Pictures folder. If you open the package you will find the folder for all your masters - the structure there can be easily decoded. There are lots of other files used by Aperture when manipulating or displaying images. If you need to get your original photo images at some time they are there. If you shoot in RAW then you might need to worry about some future time when no one supports your camera's version of RAW, but that's a different issue. You can also, in the distant future, export your edited photos to a new location.
If you have a Referenced library then you are responsible for the storage, backup and structure of those images.

CVA function and the year-period of acquisition

Hi,
Up to now we have booked the FV value manually in the SEM. In the course of FV booking we have used the year/period of acquisition and in special case the partner code. In the currency translation we have set up the special currency translation key in which the exchange rate applies directly from the implicit calculation. (This is the end of the period) It works.
We implement the CVA function in the SEM now. We customize some types of assets/liabilities, some FV differences, some tasks and document types in the CVA function.
Example:
If we have bought a new company, then generally the FV booking date and the acquisition date (the beginning date of valuation allowances) are different. The important for this is because we have to use the date of currency exchange which is same as the beginning date of valuation allowances. We get to know the final value of FV later than the date of acquisition of the company.
For example:
Unit: A
Date: 2010.12
The beginning date of valuation allowances: 2010.12
The date of capitalization: 2010.12
The original cost item u2013 acquisition:
Item: 21631
Movement type: 150
The original book value: 120 EUR
The currency exchange rate: 0,8
The bookings in 2010.12:
-     FV value- acquisition
-     Depreciation
-     Currency translation (the original book value in the group currency: 96 USD with 150 movement type)
Date: 2011.00
The opening value in the 21631 item:
000 movement type (opening movement type): 120 EUR u2013 96 USD (in the group currency)
050 movement type: 12 USD (in the group currency)
total value: 120 EUR u2013 84 USD (in the group currency)
Date: 2011.01
The beginning date of valuation allowances: 2011.01
The date of capitalization: 2011.01
The new original cost item u2013 acquisition:
Item: 21631
Movement type: 150
The new original book value: 20 EUR
The currency exchange rate: 0,7
The bookings in 2011.01:
-     FV value- acquisition
-     Depreciation
-     Currency translation (the original book value in the group currency: 14 USD with 150 movement type)
The original book value in the group currency in 2011.01 is not correct, the good value can be 18 USD with 150 movement type and 4 USD as difference u2013 050 movement type.
We have to use 2011.01 period as the beginning date of valuation allowances and the date of capitalization, because 2012.12 period is u201Cclosedu201D and we can not modify it, but the CVA is connected to the acquisition in 2010.12.
If we use 2010.12 period to the beginning date of valuation allowances and the date of capitalization the system does not book the acquisition in 2011.01. In this case we should use the year/period of acquisition. It follows the logic of the SEM.
It can be the good solution, if we can fill the field of beginning date of valuation allowances to 2010.12 in the 2011.01 year/period. After the modification we have received an error message with UCMA004 message number. (Capitalization follows the starting date of valuation allowances)
Or we would like to fix the year/period of acquisition in the CVA, in the original cost item u2013 acquisition, but it can not be, because the year/period of acquisition and the partner code fields do not appear.
If we book manually with this 21631 position, then we can fill the fields of the year/period of acquisition and partner code.
The breakdown category of 21631 item contains the following fields:
-     movement type
-     year of acquisition
-     period of acquisition
-     partner code
We do not change the currency translation, so we use the special currency translation key in which the exchange rate applies directly from the implicit calculation. (This is the end of the period)
Question:
- Why is not allowed the system, that the beginning date of valuation allowances can less than the date of capitalization?
- Why are not appeared the year/period of acquisition and partner code fields in the original cost item?
Best regards,

Thanks for the answers until now.
Surely a Day characteristic (ex. CA_DAY, derived from 0CALDAY) would work.
But we have this requirement in many other cubes (I posted only an example) and it's not feasible to create this characteristic now.
I understood the other suggestions, but the problem is not on selecting the values.
We have two restricted key figures, one for a period (filled by the users) and another one for this period - 12.
They work OK and bring the correct results.
The problem is on presenting the results, because as we have 0CALDAY in the line the results appear on two different lines.
Example:
15.07.2010    950,00
15.07.2011    980,00.
Is ther any way to present the results in the same line?
Example:
15.07.2011    950,00 (last year)     980,00 (today)
or
15.07             950,00 (last year)     980,00 (today)
or any other way?

I Have Issues - missing photos and the like

I dunno. I used to never bat an eye every time Apple came out with an update. Not the story of my life lately - since 10.4.4 and up and with related products iTunes 6.03, and iPhoto 6.
Re: i Photo - missing photos, more and more. I went investigating and the JPG's themselves are missing even missing in some cases (not just messed up thumbnails). Restoring from backup now as I speak. But this gives me the Fear. This recent list of problems in various parts of my system.
iPhoto problems have included - date stamps got whacked, so my albums are all out of tune and not in order. Missing files & directories. Thank God for backups. Also dupe files eg. img6013.jpg and img6013_1.jpg etc. etc. Also, I just bought a new Canon 20D and have been trying to import lately and during or when it attempts to import from my card, it bombs and I have to say open/reopen. Am I the only one with the Plague? After about 4 tries it worked. Larger files than my old cam, but still...
I just noticed that some of my new pics I previously imported (that showed up, but after disappeared) are in /Music/Import/Data/2000/12/ - not in the correct path and not even in the correct directories, because the dates are all indeed the correct dates - oh wait, these are thumbnails - ???
The originals are in /Music/Import/Originals/2000/12/ ???? ***!?!?!?!
I have the Fear. Any tips on what the heck might be going on here would be much appreciated.
Thanks

Hi Mike,
this is the new organization:
iPhoto 6 Library folder in the Finder
As you can see the structure is now related to rolls. Rolls are created for each folder you import and each import session from a camera.
It is very easy to change the names of film rolls within iPhoto to make them easier to find images within. Open the info panel in iPhoto by clicking on the "i" icon. Once it is opened, click on the roll title in the viewing window.
Click on the word "title" in the info pane and type in your new title. I like to use a date and text format such as 12/25/05 Christmas at Mom's, 1/05/06 my birthday, etc. Once the roll names are changed within iPhoto, they are also changed within the Finder, making it easy to locate an image.
When importing from a camera, make sure you name the roll with a date and text before the import.

Authorization loss and the future

For whatever reason, my laptop lost track of the fact that I'd deauthorized it before sending it in to have its MB replaced (Nvidia recall).
When I reauthorized, the process 'ate up' my remaining 5/5 authorizations.
(A) Is there any appeal process for this?
(B) I'm pretty sure that, a few years ago, I 'reset' my authorizations (you try having two teenagers in the house) and was told no more resets would be made available. Do I have this right? Worried about what will happen if I need a fresh authorization in the future.

Thank you!!!
Meg St._Clair wrote:> It is generally a good idea to deauthorize a computer before resinstalling system software or doing major hardware upgrades. Then, just reauthorize when you're done. This will prevent the problem.
Yep: thus this from my initial post here:
"I'd deauthorized it before sending it in to have its MB replaced (Nvidia recall)."

Are there any plans to add back missing functions in the new editor?

For Example, I don't seem to be able to set a link to open in a new window without editing html.
I also can't left or right align images without editing CSS, scripting, or opening up html view and adding an inline style.
These are just two of the small things I've come across recently - I'm sure there are more too.

There are several thread on this Nathan,
The answer is yes of course.
For images - Modern work - Left right align not that good. Your better creating classes to float the images and have those in your dropdown. You get better results as well.
You can go into your partner portal and customise the editor - Turning off the inline font stuff for example is a 100% must for us to avoid issues and the SEO implications those give.
I would highly recommend doing a .image-left and .image-right class dropdown options and in the CSS for those float:left etc with margin around the image... Heaps better output and clean markup.
