Save For Later functionality given Edwin

hi,
I have implemented application given by the Edwin Biemond(url:- http://biemond.blogspot.com/2008/04/automatically-save-transactions-with.html)
he has implemented the Save For Later functionality in the application but I am getting following error.

Hi Frank,
I am apologizes for my late reply to your response.
I tried to solve the issue first from my side but i am getting some different error.
1)JDeveloper version - jdev 11.1.3.0
2)how is the save point created?
save point is created implicitly when exits form bounded taskflow (as i setted the crirical flag)
3 )how is it recovered?
I am trying to restore it back but I am getting following error now,

****** what i did in my app
1) i have created the one taskflow. in taskflow i have one jsff page and it has one datacontrol (created viewobject and draged it in jsff. where i have some inputtext box).
2) i have added following entries in the adf-config.xml file...
<adfc-controller-config xmlns="http://xmlns.oracle.com/adf/controller/config">
<savepoint-datasource>jdbc/scottDS</savepoint-datasource>
<savepoint-manager>DATABASE</savepoint-manager>
<savepoint-expiration>86400</savepoint-expiration>
<enable-implicit-savepoints>true</enable-implicit-savepoints>
</adfc-controller-config>
3) what i want to achieve is restore the values entered by the user if he closes the form without saving data.

IRecruitment: Save for Later functionality while applying to a vacancy/job

Hi,
We are planning to introduce a couple of customizations around the 'Save for Later' functionality in iRecruitment.
Test case:
An external candidate/applicant logs into his irecruitment portal and searches for a job.
He provides some information and opts to click the 'Save for later' button midway.
I am interested in knowing which table does this 'Save for later' vacancy details data go to.
Thanks,
Vinod

Hi Vinod,
All the transactions for save for later will be stored in the hr_api_transactions.
Thanks and Regards,
Joshna.

Will "Save For Later" functionality work on BLOB datatype ?

Hi,
I read funtionality "Save For Later" from ADF Developer Guide. And tested it using JDEVELOPER 11.1.1.6 on a DB table with Number, Date, Varchar2 datatypes.
But can I create a table with BLOB datatype & make use of this functionality?
Thanks in advance for your replies.

Fill free to try, and let us to know ;-)

Distributing 'save for later' distribution pdf forms

I have created a _pub_ pdf form and corresponding data_set file for their collection. Things seem to work IF the person receiving them understands to use Acrobat or Reader to fill the form and not Apple Preview for example.
When the form was originally 'distributed' the options asked if I wanted to distribute now or save for later. I chose later and I need to send out in waves or individually.
The issue I assume is giving me the trouble now, is that I am 'attaching' the _pub_ file in an email, which does not deliver it with instructions.
How do I distribute it without recreating / saving the file with the 'distribute form' function - and risk having to recreate a new data_set each time, or breaking the links to the data_set?
The 'save for later' should leave me with a way to send them?
Thanks for your help.

Why does the Fireworks save for web function give better results than in Photoshop?

Having used the trial version of Fireworks, I have noticed that the save for web function gives greater compression and image quality than saving for web in Photoshop. Why is this?
As Adobe are not continuing in developing Fireworks, does anyone know if will they will improve the save for web function in Photoshop to match the Fireworks version?
Are there any third party companies who anyone can recommend who will process large volumes of images for web?
Thanks

One of my favourite topics ;-P
First, the save for web function in Photoshop has not seen any real updates in a long time. In Fireworks PNG export allows for fully transparent optimized files with indexed 256 or less colours, which is impossible in the save for web function in Photohop. It is unsupported.
This is one of the reasons why Fireworks does a much better job than Photoshop. Another reason is that Photoshop adds meta junk in its exported files, and this also increases the file size (and should be removed, because there are also a number of fields which include information about your setup).
One other caveat is that Photoshop's save for web functions neither allows for a choice in chroma subsampling, and instead decides automatically below a certain quality threshold to degrade the colour sharpness quality. The user has no control over this. (Fireworks also limits the user this way.)
One thing to be careful of: FW's jpg quality setting, and PS's quality settings are very different - a 50 in Photoshop is not the same 50 setting in Fireworks.
For jpg optimization I generally use RIOT (free): http://luci.criosweb.ro/riot/
(When you install, be careful NOT to install the extra junkware!)
Fireworks cannot change the chroma subsampling to 4:2:0, which does degrade the quality a bit compared to RIOT and Photoshop in my experience. Photoshop adds useless meta information, even if the user tells it not to do that. RIOT allows you to remove that information, saving 6k. RIOT also offers an automatic mode that optimizes existing jpg images without degrading the quality further, and often saves 10k or more, depending on the images.
Interestingly enough, in my tests exported Fireworks jpg images are always reduced in file size by RIOT, due to FW's jpg export limitations, without any image degradation.
In my tests FW's jpg quality versus file size turns out to be the worst of all three. RIOT generally wins, or is at least on par with Photoshop.
As for PNG export, Photoshop's save for web function is quite abysmal. No 256 colour full transparency export is possible, while Fireworks does support this.
Having said that, there is a free alternative that leaves both Photoshop AND Fireworks in the dust: Color Quantizer. http://x128.ho.ua/color-quantizer.html
CQ is an amazing little tool: with it anyone can create PNG files with full transparency and reduced to ANY number of colours! It means that a 512 colour PNG with full transparency is now very easy to do. On top of that, for more difficult images a simple quality mask brush tool allows the user to control and retain even small colour details in a PNG, while reducing the file size to an absolute minimum.
CQ is one of the best kept secrets of a Web Developer's toolkit. And it is free!
Both RIOT and Color Quantizer have a built-in batch mode. Both are available for WIndows. Not for Mac. If you are on a Mac, try imageOptim. Not nearly as good as RIOT and CQ, but quite passable.
PS to be fair, the newest versions of Photoshop do allow for export of 8bit PNGs with full transparency through the use of its Generator functionality. But again, it cannot compete with CQ. And as far as I am aware, Generator cannot be used in Photoshop's batch processing (which, btw, is very slow! For simpler daily image processing tasks I have to do in batches, I prefer IrfanView, which is lightning fast! IrfanView).

Save for later option in Global Creation

I have a business case where the user needs to save the form that he is completing for later completion. This has to happen only in the Global Creation activity. Since the instance is not created, how can I store information in ALBPM other than in the database and retrieve it when the user tries to initiate and refill the same form ?
Is there a way to do it in ALBPM where one can identify this SAVE FOR LATER request and re-open the form for completing it later?

Hi,
You can have an activity after the begin with similar form as the global creation activity and make this activity reachable when the user clicks on the 'Save for Later' button (using conditional transition right after the begin)
in this way, if the user decides to submit then...it will go the standard way ...but if clicks on the Save, data will be stored and the activity will be waiting for
the user in his or her inbox.
The bad thing here is that anytime, we save for later, an instance is created...
Hope this helps

Which menu path are you using?
Are the items available for personalization?

Elements 10 - "Save for Web" function not working.

No response when clicked. Menu closes. That's all. As far as I know, everything else is fine. Using Win7-Home Prem.

Ken --
First of all thank you for taking an interest in this problem.
Honestly, I'm not sure if it ever worked. I've used the function but I'm not sure if the last time I used it I was using Elements 8 or Elements 10. Sorry.
Yes, I have installed additional plug-ins and filters a few of which I found on the internet. Are there any that you know of that could cause Save for Web to stop? I'm guessing yes or you wouldn't have asked.
The file you asked about is there in the folder specified.

Photoshop CC is crashing regularly when I perform Save For Web function

I'm finding that my Photoshop CC, running on Windows, is continually crashing - most notably following a Shift+Ctrl+Alt+S command. Any ideas?

Sounds to me like you may have the RAM allocation for Photoshop set too high. Press Ctrl-K to go to preferences and click on Performance. If your RAM is set higher than 70%, you'll need to lower it...close Photoshop and then reopen it so the new setting will take effect.
The other thing that might be causing it is the size of the image, Save For Web is notorious (especially in older versions) for not playing nice with larger files. Try an image with a smaller pixel dimension and see if that helps. Since you are saving for web, it's advisable to resize the image before saving for the web.
One last note - when installing CC on a Win 64 bit box, make sure that the desktop icon or task bar icon actually points to the 64 bit version of CC. Photoshop CC installs both the 32 and 64 bit versions.

Is it possible to download lion and not install it? (save for later?)

I have just started the download, but after reading the reviews, and knowing that I have microsoft office 2004 which is not compatible, and it will be a while before I can buy the new microsoft packsge, I need to wait to install lion, as I need the microsoft for my school.
Does anyone know if you have to install it right away, or can you keep it for later on?
Thank you

well, it has been 3 hours already and it is still downloading ... hopefully it doesn;t take all night !
My download was about 3.5 hrs on a 10mbps cable modem. (Averages about 9mbps for me.) Many people with DSL will be slower. In my area, DSL goes down to 1.5mbps for the "basic" package and so a Lion download was several hours for some people I know.
Even if it does take "all night", the installer will pause at a "continue" button, which you can then cancel the install at that time. So you don't have to watch the download continuously, if you're worried about that.
...I have seen a lot of bad press on these boards ...
As someone once said elsewhere: these forums are like hospital emergency rooms. You only see sick people here. Those that are well and not having problems tend not to post "all is fine with me" and such. While there are some legitimate issues with some people's upgrade, we just won't hear from the millions of others whose Lion upgrade went just fine. And some of the "bad press" is people just not liking any of the changes to the way Lion does things. (i.e.: Resume, reversed scrolling.) To some, any change is bad and they immediately don't like it without seeing if new feature is actually is better or not. Which I find ironic since if one really doesn't like change, why would one upgrade in the first place?

Photoshop CC: Save For Web function does not update filesize previews when I change filetypes

I recently tried to save some web banners and wanted to optimize for smallest filesize with best looking output, and as I changed filetypes from Gif to Jpeg to PNG, the preview at the bottom of the window that usually updates with estimated filesize was not changing and the preview image would not change as well. The issue made it impossible to predict the output and required that I actually save in all the variations, then reopen them to see the end result.
My software is up to date.
Not really sure what it can be.
Please help.

Same issue. Hoping someone responds to this thread soon

Advice-Buy early Mac Pro 2gz 4GRAM for £690, or save for later model?

The earliest model...... just want to get some opinions here before taking plunge..drawbacks for me 1)I don't like the idea of not being able to update the OS 2) dont like the fact it doesnt run 64 bit natively...plus side 1) It will be a major upgrade for me, as am using g4 ppc and can run Snow L 2)I can afford it (just) can I pick some minds re price and how long its likely to last? I mostly use my mac for video and music..what exactly will I need to watch HD video? am wavering whether to milk my g4 until I can save enough, or take the plunge and start saving again...

I think you are both mistaken, and exaggerating. Plus this got some good input from your friends on MacRumors.
Booting a 64-bit kernel is all it lacks as you should have gathered by now.
Runs 64-bit apps fine. There were lots of threads on forums etc about 64-bit drivers/mode and what it means (or not). Maybe in 3 yrs will 64-bit kernel matter more, but today? now?
I don't know what US$ is but if you want "more modern" Apple Store Specials.

3 yrs ago when it was new it would have been a great upgrade from any G4. Today you could buy an iMac and probably be happy and satisfied.
So the only reason is you think Snow Leopard might help, and in that department I'd say wait a year or until 2011. No compelling reason today.
Good reason to stay with 3 yr old Mac, it runs 10.4.11 (Intel, so you need the OEM DVD it came with probably). Tiger for Intel Mac was never sold retail.
Best reason to buy: you need it and can't do what you need now; these things are darn quiet!
Plan on upgrading the graphics to ATI 4870 and throw in an SSD system drive, plus a 1TB data drive. I'm sure you'll find it fine.

"save for later download" feature?

Hi all,
Like some folks, I have dial-up at home, much better connection at work. I would love to "bookmark" selections that I make at home so I can bring my laptop to work and then get 'em all at once. Does this feature exist?
TIA

If you plan to purchase very soon from the time you select an item, then using the Shopping Cart to save your selections as Paul suggested should be fine. If you don't expect to purchase for several days, though, then using the Shopping Cart is not a good idea. Items can go unavailable from time to time for various reasons, and if you have one sitting in your Shopping Cart, it can corrupt the cart, something only the iTunes Store can fix it.
A safer method would be to just create a normal playlist (call it "wish list" if you like) and drag the tracks you want to remember into it from the iTunes Store. That will save them for future purchase.
Regards.

Possible bug in Save for Web -- Color Changes!

Hi,
I'm new to CS3 and also new on the Mac (and also to thiis forum). So I might be overlooking something but I am an experienced user user of Photoshop 7 on a pc. Never had a problem like this.
When I try to save an image with the color #c51076 as a gif using the Save for Web function I get a totally different color. Much lighter!!! I don't get it. I can't get the color I want.
I jjustt found out that iit also messes up webcolors: it swaps one webolorr for another.
Does anyone know a solution?
Thanks!

Thanks for sharing. First let me say I think it's really great that you have shared all the documentation about these color issues. I read your page before posting here, and I tried each of the suggested solutions, and wasn't able to fix it. Maybe it is a problem with the Mac OS and the way it displays images non-color managed images. But it's not like all the images I view on Firefox are dull-just the ones I've edited, because they appeared different in CS3.
As I mentioned above, I am not the only one who is having this problem, despite trying all of the fixes suggested (see the link to forum thread posted above). I think my next step is to schlep my MacBook over to the Mac store and see if they can verify my monitor profile. But if anyone else has any suggestions, please let me know!

Gif becomes grainy/pixelated in 'Save For Web'

Hello! I recently switched laptops and I have been having major issues trying to regain the quality gifs I used to make. After I have my gif set to go, I go to save it in 'Save For Web'. This is where all of my problems start. My gif no longer looks smooth, but the entire thing has a grainy or pixelated look -- and it doesn't change no matter how I fiddle with my settings. When switching from the 'original' to the 'optimized' tab in the save for web page, you can obviously see a loss of quality. It may be slight, but it makes a huge difference to me.
Here's a side by side reference:
Not sure if it will help, but here are my settings when saving (I have changed from 'pattern' to 'diffusion' and nothing changes):
Thank you for any help you can provide!

First, JJMack is correct: lots of colours (around 32100) in this example do make it harder to convert without grain.
Second, the quality of the GIFs you produced in Save for Web (SfW) prior to the purchase of the new laptop were never any "better" - it merely means that the previous screen was unable to display the results at a decent enough quality to actually discern the differences between the original and the GIF version with reduced colours. Screen quality does matter.
Second, Photoshop's Save for Web colour reduction algorithms are quite old-fashioned, and (far) better methods are available. Not in Photoshop, however. For a good conversion you will have to look elsewhere.
Here is the original version @2x zoom (32101 colours):
Photoshop's version. The best visual quality I could achieve in SfW (diffusion dither at 81%, perceptual). Obvious banding issues, and a very grainy result.
Next up: RIOT (Radical Image Optimization Tool). RIOT features a newer "NeuQuant neural-net" colour quantization algorithm. Notice how the gradients are quite nicely retained, although here and there some issues pop up (lips/makeup, building, arm highlight, and greenery are missing colour). Overall, though, the final result is much less grainy looking than Photoshop's effort. At the expense of smaller areas with unique colours.
Next, let's try Color Quantizer with standard settings, a two factor gradient priority, and 256 colours. Dithering was set to Shiau-Fan @75%. Slight banding in the lighter areas of the background, and the building and lips are again missing colours from the original. Much less grainy than Photoshop's version.
Colour Quantizer features a quality mask brush, which allows us to safeguard smaller areas with unique colours from colour degradation. I painted a mask for the lips, the building and greenery in the background, the skin of the woman on the right in the background, the lighter area around the vent, and the forehead to preserve those areas' quality as much as possible.
I feel this result speaks for itself. There is slight banding visible in the lighter area of the wall on the right, but still much less pronounced compared to SfW's version. The colours are all there, especially the important ones for the makeup and the smooth facial tones of Kate. The shoulder's highlight is also preserved nicely. Even the woman on the right in the background looks spot on (which was yet another sore point in SfW's version).
Arguably the best version. Far superior to Photoshop's failed effort.
Fourth, if you are still using GIF to optimize still images: STOP NOW. GIF is terrible in comparison to properly optimized and compressed PNG files. Only use GIF when small animated movies are your goal.
Here is a 512 colour version produced in Color Quantizer (Photoshop's SfW function lets us down once more, unfortunately: there is no option to reduce an image to 512 colours for PNG):
This last version is visually (mostly) indistinguishable from the original, and clocks in at only 52kb.
Of course, if you are saving this as a still image, jpg should have been your choice in the first place, since it is a photo.
Conclusions:
- avoid Photoshop's "Save for Web" function if your intention is a quality colour reduction;
- avoid GIF for still images. Either use PNG or JPG. JPG works best for photos;
- avoid Photoshop and SfW if your intention is to optimize PNGs well. Sfw cannot save PNG files with reduced colours beyond 256 colours;
- fall back to external and/or online utilities to optimize PNG and GIF files. Color Quantizer and RIOT deliver better results than SfW. Or use online optimization tools to optimize animated GIFs (Optimize animated GIF). You can also optimize each frame in a tool such as CQ, and then import the individual frames into a animated GIF utility. Remember, each frame can save its own custom 256 colour palette;
- for optimum quality a quality mask tool, such as the one in CQ, is a very effective and efficient method to guarantee the best possible conversion;
- file sizes of png files created in external utilities almost always beat the ones generated in Photoshop and SfW;
- a better choice to export PNG files is Photoshop CC Generator. At least that one allows for 8bit PNG files with full transparency (another missing essential feature that SfW fails to provide).
