Report and Page Rendering question

Hi,
I have a report page that I've added a new region for entering search criteria. Everything is working fine, except one small thing. When the page loads for the first time, it still returns all rows just as it did before I added the criteria region. How can I change the report so no rows are returned during the pages initial rendering, but only when the criteria is submitted?
Best Regards,
Brian Peasey

The easiest thing would be to put a condition on the report region to only display when PX_SEARCH is not null.

Why is connection speed and page rendering so much slower in FF 3.6.13?

After installation of the 3.6.13 upgrade, website connection and page rendering speed became significantly slower than in all previous versions. I searched the knowledge base and Forum and found this post:
http://support.mozilla.com/en-US/questions/668695#answer-108852
After changing settings as described in the post, speed was easily more than doubled.
I'm wondering if anyone else has experienced the slowdown in connection and rendering speed with 3.6.13. And also why, if the settings worked so well for me, they aren;t standard in FF?

Crystal Reports and salesforce integration question

I have a question about Crystal Reports connectivity to salesforce. We are running Crystal Reports version 14.0.4.738 RTM. When you create a new report and use the Database Expert, you can select www.salesforce.com as the data source. I would like to know if the built-in connection to salesforce is secure. Is our data secure in transit from salesforce to Crystal? Is my password passed in clear text? That kind of thing...
Thanks!

Pete,
As any SAP product Crystal Reports is going through users data security check before any new release. It includes any bult-in connection that comes as a part of product installation. Unfortunately I do not have any document for a reference, but your user password is not exposed in CR connectivity.
I think I should mention that prior to Crystal reports 2013 (version 14.1....) we used our own java based driver, but starting from CR 2013 we are outsourcing the driver to a third party and it is ODBC driver. It means the SFDC driver will automatically change if you decide to update your CR 2011.
Hope it helps,
Vitaly

Apex 4.1 Custom error function and page rendering

Hi
I have setup a demo application at http://apex.oracle.com/pls/apex/f?p=19820:1 which is a simple testing application for testing of the apex_error_handling_example function Patrick wolf put into Oracle documentation. I have setup a error on the page rendering of page 2 in the application. The error process contain this simple error code declare
v_id number;
begin
select 'x' as one into v_id from dual;
end;
which generate plsql numeric or value error. The process is running before regions on page rendering on page 2. I have also created the same error process on page processing before DML processing on the page. When i insert apex_error_handling_example into the application level and run the application the error is not caught and the page is rendered as nothing was wrong. When the page is submitted the error function is executed and work correct.
When i remove the error function from the application the error is caught and displayed on the APEX error page with the detail link for drill down to show more about the error.
Any which can tell what is wrong with the setup i have done. The error function apex_error_handling_example setup is simply a copy/paste from the documentation with some few debug message put into a logging table.
kindest regards
jon

Hi
Yes, when you submit the page the page processing is displaying the error message inline, but it does not show the same error on page rendering for page 2, if i remove the custom error function it will show the error on APEX separate error page. The debug output from the page 1 is as following:

Subtab partial page rendering question

Hi,
I have a subtablayout bean with two adv table regions. The subtab links in the subtabbar bean are set to partial action. When I run the application for the first time, the subtab one is shown and clicking on the second tab, the VO tied to the second adv table is fired but I see only one row in it.
When I click to go back to the first tab and then back to the second tab again I see all the records of second VO now.
I change the action type from fire partial action to fire action for the second tab link. After this, I see all the records displayed the first time I navigate to second tab.
What should I do to see all the records in the second tab the first time I navigate to it while keeping the partial page rendering mode.
Thank you,
Arun

Thank you for your time Srinath.
I used getCurrentRowIndex on the VO tied to the second tab and it returns -1 for the first time as well as subsequent navigations to the second tab.
The table navigation shows "1-10 ..Next" (my setting is to show 10 records at a time in the advance table). It is not showing the 200-201 range.
"getRowCount(..) would explicitly re-execute the query. This answers why you see the whole set of rows when you have this in the SOP. "
I am not sure what you mean here..could you please explain. I understand 'getRowCount would re-execute the query' part. But the normal behavior for the advance table should have been to show the first 10 records since the VO has already been executed once.

Raw HTML and Page Rendering Issue happening at Random

We are an internet retailer (BettyMills.com) and recently started having customers and our internal users reporting two issues.
It is random, but due to the high volume of traffic on our website, it is a high enough frequency to be very troubling.
The webpage does not fully render, and the customer sees a dump of the page without formatting, just a listing of all the links on our page and the images dumped out and out of place.
We thought this was initially a comcast DNS issue, but seems it is happening beyond that.
I'm on Firefox 19.x and I've never had the issue, but I've witnessed it on about half dozen of our staff computers and external customers.
Has anyone seen this issue or any way to know how to trouble shoot it?
We can't recreate it on demand so very difficult to debug it.

Sorry for the simple question but: Are you in video group?
Also, it might depends on the order the modules are loaded. That's the case with my Intel card. Try loading agpart first:

Crystal report and SAP system question

Hi,
I try to report off the SAP system using crystal reports without installation of the BOE server. But with very few knowledge of the SAP system, I am not clear of how and what to do. The following is what I have done:
1. From the client machine, I open the crystal report 2008
2. click "SAP" button and then click "Create New Report from a Query"
3. Select the system and enter the login user name/ password information
4. A dialog "Select Query for your Crystal Report" displayed.
    But under "Favorites", no entry found
    Under "Roles", no entry found
    Under infoAreas, there is a "Technical content" on top level and "Exchange Rate Type" is under it. I select this exchange rate type in the report, but it is an empty table.
If I use the same user name/ password to log on the SAPGUI, I am able to see lots of data.
Does anyone know what are the appropriate configuration steps to make the tables/views in the SAP system visible in the crystal reports? Could you please give me the details? Any help is appreciated.
Thanks,
Vicky

Hi,
are you trying to report on top of a BW query (mentioned in step 1 and 2) or you trying to create a report on top of tables (mentioned further down).

Jasper Reports and ADF: JRDataSource question

Hi all,
I am stuck with a problem creating a dynamic report with jasper. I want to use data from a VO or binding, not via a select in my report. Here is were i am at right now:
BindingContainer bc = this.getBindings();
DCIteratorBinding iterBinding = (DCIteratorBinding) bc.get("VO1Iterator");
RowSetIterator iter = iterBinding.getRowSetIterator();
Row[] matrix = new Row[iter.getRangeSize()];
int i=0;
while(iter.hasNext())
matrix[i] = iter.next();
//output to my msg facet:
fc.addMessage(null, new FacesMessage("Hour FROM: " + matrix.getAttribute("HourFrom") + " TO: " + matrix[i].getAttribute("HourTo") + " FACTOR: " + matrix[i].getAttribute("Factor")));
i++;
iter.closeRowSetIterator();
JRDataSource myDS = new JRBeanArrayDataSource(matrix);
In my report i am using $F{HourFrom} to access my values, but i keep getting:
Jasper Error:Error retrieving field value from bean : HourFrom
I'm using Jdev 10.1.3 with oracle 10g .
I understand that i'm not accessing the JRDataSource correctly. Hopefully someone can point me in the right direction.

Forefront Endpoint Protection 2010 Antimalware Activity and Antimalware Protection Summary Reports aren't rendering properly.

The Antimalware Activity and Antimalware Protection Summary Reports aren't rendering properly. When I export them to PDF, they look normal but when I run either one of these reports through they don't display properly. In the Antimalware
Protection Summary report, the Latest Antimalware Protection Summary title bar has been extended and the Status legend is coved by white space and Latest Antimalware Definitions Summary title bar has been extended and Period legend
are covered by white space. On the same page the Antimalware Protection History-Week has been flushed to the right to where it only dispays Antimalw and the Antimalware Definitions History-Week has been flushed to the right to where it only dispays
Antimalw. On the Antimalware Activity the Actions legend has been flushed to the left.

This is an old question but you may try it using the latest version of Forefront Endpoint Protection or System Center Endpoint Protection and let us know if you are able to reproduce the problem. There are many improvements in latest release of SCEP and
FEP.

Print the report on page has width larger than height and not landscape mode

Hi,
I'm trying to print report on page (Width: 18cm, Height: 13cm) which the width larger than the height.
The problem is windows keeps changing the page oreintation to landscape and when I change it back to portrait its changing the width to 13cm and height to 18cm.
I'm using dot matrix printer to print the report, if i put Landscape , printer is printing the text in horizontal.
Already i have tried to setup the custom for on printer, and used custom page size but it is changing to landscape.
I need to print the report with out preview, direct print top printer, NO PDF....
Thank you .....

Hi Anil,
After testing the issue in my environment, I can reproduce it. When I set (Width: 18cm, Height: 13cm) as the Report Page size, it would automatically convert Orientation from Portrait to Landscape. Because the Orientation displayed is dependent on the page
width and page height of the report.
But in my scenario, the Orientation option just change the Width and Height sizes, it couldn’t affect the text rotation. I guess this issue can be caused by the printer and printer driver, please try to update them. Reference:
http://stackoverflow.com/questions/15244336/printing-in-landscape-or-portrait-automatically-rotates-text-ssrs?lq=1
Hope this helps.

How to develp a subreport in the same page of the main report and processed when is called

SSRS 2012
Hi guys,
I am developing a report that includes a subreport.
therefore The report is made up by 2 sections:
1) Show a grid (several rows - may be 100 or more - and some columns). It represent high level info (Each row represent a specific item)
2) The user click on a Row/column (eg: Item1, to see details that must be shown as graph.
Here the problem: Searching info about SSRS reporting for subreports, drilldown, nested report and so on, no ones accomplish the requirements for the following reasons:
1) Subreports: NOT open in the same page. The user must <go back> to see detail for other items, such as Item 2....
2) Nested and DrillDown: Process data as the Main report (they are hidden and displayed after user action). In my case this leads to performance problem, because: if the main report has 200 objects (it means 200 graphs processed and hidden at the same time
for the main reports).
3) DrillThrough and Subreport: The detail data are processed only when the user select the interested item in the main report. Here the problem: the report is shown externally.
Please, it there any possibility to have a subreport (or anything else) to be executed in the same report as the main report and processed only when the user make action?
Thanks for your help.

Hi Fasttrack2,
According to your description, there is a main report with more than 100 rows of summary information, when users click the item of the row, the report need to jump to detail information shows as graph. The problem you are facing is that you are not sure
subreport, drilldown or drillthrough report should be used? You hope to set display detail information in the main report and keep high performance of report.
In Reporting Services, each subreport instance is a separate query execution and a separate report processing task. Subreports are recommended when there are just a few subreport instances. We should not use subreports inside a group when there are many
group instances, instead, consider using drillthrough reports. Drilldown reports process all data even when the data is first hidden. In order to improve the performance of the report, we can split drilldown reports into parameterized drillthrough reports,
because Drillthrough reports do not run until a user clicks the drillthrough link in the main report.
In this case, we can consider using drilldown or drillthrough report. In drilldown report, when we click a plus or minus button to expand or collapse a section of a report, the detail data will be displayed in place. By using drillthrough report, when we
click the link in the main report, the detail data will be displayed, we can come back to the main report by click return button in the drillthrough report.

More than one column retrieved in "report and form" page

HELLO!
let's see if anybody can help me with this... i'm sure it's a stupid problem but i really don't know how to solve it.
when i create a new application with APEX, i want to add a "report and form" page. i select the table where de data is, and then click on add page. then i go to the page definition for the form that just has been created but there's no option for selecting more than one column as the link column...
i mean, i want to show a report with all the columns from the table and then, by selecting one of them, the form should display that column but the problem is that the primary key of the table is formed by 6 columns and i always receive the "more than one column retrieved" message as it's trying to retrieve the information using only one column. is there any way to make the link column be composed by 6 or 7 columns??

APEX can handle 2 primary key for one table (if you are using the automated fetch row and the automated process row).
In your case, you'll have to create your own "fetch process (page rendering)" and "DML process (page processing)".

Partial Page Rendering - newbie question

I am a newbie to ADF and I am in the process of trying out the tutorial "Developing Ajax-Based User Interfaces with ADF Faces Rich Client Components" http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_56/jdtut_11r2_56.html
I have a question regarding Step 4. I am not very sure where to post this question, if this is not the correct forum, pardon me.
Under "Step 4: Implementing Partial Page Rendering" there is this following comment
In order to have a refresh of the Product Details when you select another row in the Product table, we need to set the Partial Rendering behavior. To do so, perform the following steps:
Similarly On Step 3, sub step 26 states "Finally, double-click on any of the rows in the product table. Notice that the Product Details pane does not reflect the change in the selected product. To implement this synchronization, we need to add partial page rendering functionality."
Question: even before I tried any of the changes mentioned in step 4, I am finding that the product details pane does show information related to the product selected on the panel collection (in other words it is displaying the master detail information automatically). What am I missing here? As per the training document it is supposed to work only after implementing changes mentioned in step 4. Can one of you kindly point out if this is a mistake in documentation or if I have misunderstood the statement?
Thanks

Frank,
Thank you very much for the quick turnaround; I appreciate it.
Yes, I am using what seems to be the latest version of JDev (11.1.2.3.0); and yes the ChangeEventPolicy for the iterator is set to "ppr". Thank you for pointing that out.
Does that mean ppr is standard for most components (when I say components, I mean adf tables, button's etc), don't we need to add any special events to get that to work?
I just wanted to see, what will it due if the ChangeEventPolicy for the iterator is set to "None"; made the change saved it, there were two iterators I changed the "ChangeEventPolicy" on both to none; saved it and ran the page. It worked same as before; I was expecting it will not load the corresponding data at the child level, but it did. can you kindly point out what is wrong.
<executables>
<variableIterator id="variables"/>
<iterator Binds="root" RangeSize="25" DataControl="StoreProducts" id="StoreProductsIterator"
ChangeEventPolicy="none"/>
<accessorIterator MasterBinding="StoreProductsIterator" Binds="products" RangeSize="25" DataControl="StoreProducts"
BeanClass="tutorial.model.Product" id="productsIterator" ChangeEventPolicy="none"/>
</executables>
Thanks

PPBM5 Questions and GPU Rendering Concerns

Bill and Harm, i figured i woud post this here instead of a private email so as to get some opinions and input from others.
I am a bit confused with the logic behind the gpu testing and want to make sure i understand how this is working and make sure i dont have any problems with my machine.
I just wiped out my 8 core, 20GB ram, SSD, gtx 460/2GB, machine and put a fresh win7/64 on it with cs5 and nothing else.
i am planning on doing various tests with the SSD, then SATA Raid, then my 4gbit fibrechannel in combinations.
My concern is over the gpu acceleration and timeline rendering. My basis for wanting these gfx cards with cs5 is on the PPBM results showing all kinds of double digit speed gains with MPE enabled.
I have 8 of these machines and need to upgrade them all so i am concerned to make sure what i am doing and what i am getting for it.
my first obvious question for everyone else is when you load the benchmark in what do you see on the timeline? i have all yellow except for two small red lines near the end of each section where the curtain and cube effects are at.
Now when i hit the spacebar to play the timeline at starts out ok but then hits the 8 second mark into it and chokes out the rest of the way skipping frames and drawing maybe 3-5 frames per second until it gets through the rest. Is this what happens for everyone else or does your system play the yellow area smoothly?
Is this a by-product of my manually putting the 460 into my supported cards file and premiere not properly calculating what the gpu can and cannot accelerate?
Now as for the benchmark testing itself when i hit enter it simply renders out those 2 effects that have the red line then starts playing the same choked out skippy video as before.
So if this speed is calculated and then the speed of my cpu rendering the entire timeline then how is this an effective comparison? if i simply remove those two effects at the end then i still have that big complicated timeline and yet if i hit enter it just plays choppy video instantly and nothing is rendered, so compared to my cpu thats a bazillion times faster but i dont get anything out of it as the video doesnt actually play with the gpu.
My real concern and need is flat out rendering speed for encoding. i had high hopes that getting a video card with hundreds of cores on it would magically render out mpeg 2 files 10-20x faster then my cpus can.
i saved out a pic of my cores when i am playing the timeline, you can see they are not being maxxed out.
Before i wiped my system out i tried the trial version of the mainconcept gpu encoder and it went slower with the gpu than it did with my cpus. Their email response to me was that gpu rendering is more of an advantage against slow cpu systems. and my cpu's were too fast in comparison. I find this hard to believe in that my system is several years old now. thier own performance comparison charts show a tremendous speed increase over modern I7 processors.
On a side note - DONT INSTALL MAINCONCEPT TRIAL ENCODER!- it hijaacked my mpeg encoding/decoding even when i wasnt using it and it was watermarking all my stuff in premiere with its logo!
I also have been using a program called canopus procoder which does great encoding with multi cores, a standard dv to mpeg2 encode on my system maxxes all 8 cores and renders about 14x faster than realtime.
I hoped a cuda card could increase this speed for me and render faster then that directly out of premiere. I would think during rendering your cpu's and gpu's would work together at 100% usage to go as fast as possible. i would like to see 20-30x realtime speed for mpeg2 encoding in my situation.
Thanks and i look forward to any input or help or even a simple "click on this and yoru problem is solved"

harm, thats kind of funny actually, you show us a report of your dropped frames on playback then say you cant tell us how because of NDA, yet we obviously know you have an app that reports the dropped frames during playback
But thats ok, anyways as far as your ppbm goes i love it and dont mean to desparage it in any way, i have been a big supporter and love the work you and bill have put into it. I am really just trying to have a better understanding of how it works.
My concern is more about premiere as opposed to ppbm. I want to know if my system matches what everyone else sees, when i load the project is get this:
i just want to make sure everyone else has the same tiny red sections that premiere feels it can't play.
previously premiere has always either played in realtime at 30fps or shown a red line which needs to be rendered. then if you render it you get full 30fps playback on the entire timeline.
now with this new gpu workflow i can only render those two tiny little red sections and the rest of my timeline plays at about 2 or 3 fps from 8 seconds into the timeline until the end.
So I actually have no physical way to see my video at full 30fps without changing to software mode and rendering the entire timeline? or am i missing something here?
Isn't premiere supposed to recognize when it cant keep up with 30fps playback and change that section of the timeline to red?
And on a side note i still have to say i am fairly annoyed that an adobe employee took it upon themselves to move my thread into the unpopular generic premiere hardware forum, when this is a very specific premiere cs5 question thread. I have never even looked in this forum for any cs5 posts before now and had hoped to get more feedback from users in the main premiere cs5 forum. A lot of companies like to treat their customers well and the old addage "the customer is always right" doesn't seem to apply anymore. My company probably has purchased over $1,000,000 in adobe software licenses over the years which i feel would make me a valuable customer, and i have some important questions i need to ask about the new version of your software and how it is supposed to work.
thanks
