Problem with PPR in Jdeveloper 11g

Hi All,
I'm working with the Jdeveloper 11g.
My problem is I have a command button/ Command link in a jspx page. Whenever I click on the command button or command or any action generating components the whole page is getting refreshed(PPR).
I wrote some internal logic in the constructor so as to display the tree. It is calling the constructor again and again when I'm clicking on the sub nodes of the tree. I think the entire page is getting refreshed and the methods are calling again and again.
Is there any way to overcome this problem.
Could any one help me out.
Thanking you,
regards,
Satish.

Satish,
I need more information to triage this issue. Do you have the partialSubmit attribute set to "true" on the command component? Does your JSPX contain an <af:document> tag?

A lot of problems with Oracle BI SEE 11g

I have a lot of problems with Oracle BI SEE 11g
1. I upgraded my BI SEE 10 repository and can it openning in offline mode.
2. I can't deploy my upgraded repository in EM MW Control 11g - when i try to open Farm_bifoundation_domain->Business Intelligence->coreapplication, i get error "Stream closed
For more information, please see the server's error log for an entry beggining with: Server Exception during PPR, #41".
Opening Logs by EM control doesn't work too.
in file middleware\user_projects\domains\bifoundation_domain\servers\AdminServer\logs\AdminServer.log i see this event:
<Error> <HTTP> <oratest.itera.ru> <AdminServer> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <b639ac3e56e9a463:bd6fa7f:12ac7271e09:-8000-00000000000009e8> <1283408423378> <BEA-101019> <[ServletContext@329875093[app:em module:/em path:/em spec-version:2.5]] Servlet failed with IOException

Have you any ideas?
3. Ok, i taking sample repository and adding a new datasource in it:
Database: Oracle 8i
Connection pool:
Call interface OCI 8i/9i
Data source name:
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (Host = oraapp) (Port = 1521) ) ) (CONNECT_DATA = (SID = MYSID) ) )
This settings are working fine in BI 10.
In BI 11g i get this funny error: "The connection has failed". I lost my time in attempts to connect to Oracle DB 8, but have not results. After that i hacked button "Query DBMS" at "Features" tab, pressed it and when get error "ORA-03134: Connections to this server version are no longer supported.".
Therefore Oracle 8 DB as datasource not supported. Am i right?
4. In sample repository i added oracle DB 10 as datasource, then added two dual tables and their connection to all layers.
Now i open BI Answers, and trying to create report with one dummy column, Now i have this error:
Error
View Display Error
Odbc driver returned an error (SQLExecDirectW).
Error Details

Does anyone solve this problem?

Turribeach, Thanks for you time.
1. It was not a question
3. Yes, i have read platforms, but not supported datasources. Now i see, that BI 11g support as datasource Oracle DB 9.2.0.7 or higher. I am sorry.
4. I'm using OCI connection type
Now i recreate Database in Physical schema and answers is showing report data for me! But only from one table, when i use columns from to tables from one datasource, i geting error:

Problem with rank in OBIEE 11G

Hi,
I have a problem with the function rank in obiie, i have two columns the first is the id of employees, and the second is the rank of revenues of employees, when I filter one employee and the rank is always 1, someone can help me?
Cumps

I do not think this is going to be possible using a traditional filter on the query.
In order for the rank function to correctly work, it has to be aware of the other column values in the query to assign a rank to each row. When you filter the query ( either on the ID or the Rank) all of the other column values will be FILTERED OUT of the query. Rank will only see 1 value in the column, so it gets the #1.
You have 2 options here:
Selection steps: use selection steps to "keep" only the rows you are interested in. Selection steps basically allow you to"hide" some of the rows your query has returned, but still calculate against them for aggregate functions. If you are focusing on a top or bottom % this solution will work well.
If you are hell-bent on using a filter, the only way you will be able to get the rank function to work is to calculate the rank in a 2nd query, then use an outer join to attach the rank column onto your filtered employee query.

Problem with PPR in ADF

I have a problem with Partial Page Refreshing in ADF faces. what my requirement is I have Table with two cells. One cell contains the ADF Tree component. This tree component can expand their children. If you click any of the tree component then the details of that component displayed on the another cell. I want to display contents with out refreshing the entire page.

let`s give you what i did :
I adding two dataPage ,First one for browse employee and second one for deleting an employee .
So, i did same what is write in a bove link for deleting
but when i run it :
first browse the employee
Then when click the link of delete it is go to DataPage that`s name( Delete employee) .So , when click the button delete
it is return to the first DataPage(browse employee)
and you will see that row is deleting but when go to the DataBase
you will see the row not Deleting.

Problems with ADF in JDeveloper 10.1.2 - Focus Handling in a Table

Hi there,
we have a problem with the focus handling in a JClient-Table
(embedded in a JScrollPane).
When I insert a new row in a table (e.g. with 2 columns),
and insert in the second column some text and
(while the focus is still in the second column) then
add again a new row to the table, the text from the
"lost-focus-column" is moved to the new row.
Example:
Add row 1 (columns Name, FirstName) => Result:
Row 1: Smith John
Add row 2 => Result:
Row 2: <empty> John
Row 1: Smith <empty>
Is that a bug of the framework or does anyone know a workaround for that
behaviour ?
Tanks a lot...
Cheers, Claus

Hi,
problem solved. It's a Swing problem. The following line of code is neccessary:
dataTable.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
(dataTable is the jTable).
Unfortunately other Swing-Components (e.g. JTextField) don't have that
client property :-(.
Cheers,
Claus

Serious problems with TopLink in JDeveloper

Is there any sane way to regenerate TopLink Java objects from Oracle tables? Specifically, I have changed an Oracle table and need it reflected in both the Java object and the toplink-mappings. I don't see any way to do this in the IDE so I've resorted to deleting the Java object, and removing the descriptor for that object; then recreating both. Now, this has opened a huge can of worms.
First of all, if the .class files for TopLink Java objects already exist, the IDE will refuse to overwrite them: instead it will append "1" or "2" etc to the new object. The Erase from Disk option in JDeveloper does not remove class files -- just source. So I need to physically go deleting class files every time I need to recreate a TopLink Java object.
Secondly, removing the descriptors within JDeveloper does not appear to take effect unless you physically restart the IDE!!! This issue drove me nuts for two days. Upon deleting and recreating a TopLink Java object, the fields in the object were continuously being appended as "field1", "field2", "field3" to the class descriptor. Only shutting down the IDE and restarting it seemed to reset the mapping file.
Thirdly, for whatever reason, JDeveloper will sometimes completely forget what "toplink-deployment-descriptor.xml" is and never allow you to generate it again. Instead it generates something called "toplink-ejb-jar.xml" which promptly blows-up any POJO portion of my project with a "Can't find toplink-deployment-descriptor.xml" error.
Is anyone else having these problems or are you all using Hibernate?!

Hi Anuj.
Your sequence doesn't work for me. The only way I can reliably rebuild my TopLink project is as follows:
1. Clink on TopLink Mappings, and Remove descriptors from the TopLink Structure pane
2. For all descriptors in step 1, select the TopLink Java objects and "Erase from Disk"
3. ** For all Java classes selected in step 2, manually delete all the corresponding .class files from the project's class directory **
4. ** RESTART IDE **
5. From Project node, generate TopLink objects anew

Problem with SRDemo application in 11g

I followed the link http://www.oracle.com/technology/products/jdev/tips/muench/1013srdemo/index.html and migrated the SRDemo application to 11g build.
When I login to the SRDemo application , I get the below error. I am able to login, but do not have access to any application facilities.
Failed to checkout SRService application module. Ensure your datasource name is SRDemo [case-sensitive!] and that connection settings are properly defined for a database with the SRDEMO schema installed. See server log for more exception details...
I re-checked my DB connection in Jdev and everything looks fine. I am launching the application from Jdev ( embedded OC4J). I am using the 11g Tech preview 2 build ( 4684 ).
What might be going wrong ?
Thanks

Hi,
try changing the database connection from JavaEE data source usage to JDBC URL. Usually this solves the problem

Problem with EventHandler in OIM 11g

Hi All,
I followed the Part I(Chapters 6,7 & 30) in pdf file shown below
http://download.oracle.com/docs/cd/E14571_01/doc.1111/e14309.pdf
I developed the plugin and registered the plugin for custom eventhandler.
Iam not able to see the defined eventhandler in design console .
I am running weblogicImportMetadata.bat (import specific metadata files into the MDS database) as specified in pdf document after making necessary changes.
After restarting OIM server ,the server is not starting , and showing errors like " target invocation exception","null pointer exception" etc.
Have anyone done the EventHandler in OIM 11g , if anyone done please provide the followed document link.
Please suggest to solve the issue.
Thanks & Regards

Hello Satish,
You won't find the eventhandler in the design console. This is by design.
I had a similar error. Hope this helps you.
Verify your EventHandlers.xml file. For me one of the entries, particularly stage="preprocess" had the letter 's' in uppercase (Stage="preprocess"). This was the source of my error below.
<An error occurred while initializing service : {0}

There is definitely a lack of clear documentation around developing plugins (e.g. oim.home in ant.properties should point to OIM home/server).
I worked with Oracle support and provided some feedback. They are going to publish a KB article soon. I now have a preprocess eventhandler that seems to work.

Problem with uploading files in 11g

I upgraded the pre-installed APEX 3.0 in Oracle 11g to version 3.2. I created a form to upload files to the table htmldb_application_files and then copy the transaction to my custom table. However, after I "saved" the transaction, nothing happened. No file was uploaded into the htmldb_application_files table. Also, the "save" process took a while to finish.
I used to do this in my other applications in Oracle 10g and everything worked fine. Is it an issue with Oracle 11g?
Thanks.
Andy

I think I just did something wrong myself. I was finally able to upload the file. However, I wrote the following procedure in my package but wasn't able to download the file from the report. Do I need to grant any privilege from the system user?
Also, does anyone know how to convert a BLOB table into 11g Securefiles table?
Thanks.
<pre>
procedure download_birth_cert(p_vrds_birth_cert_pk in number) is
v_mime VARCHAR2(48);
v_length NUMBER;

SubTabLayout problem with PPR (bug?)

Hello,
I'm using JDev10.1.2 and found out that subTabLayout does not respond to the partial page rendering (PPR) as one would expect.
In my example there is simple subtabs switching that does not renders both subtabs, only upper one is changing.
Correct behavior can be achieved if using fireAction instead of firePartialAction.
Is this a bug?
Example:
<subTabLayout>
<contents>
    <messageStyledText text="${sessionScope.subTabIndex}" prompt="Selected tab:" id="message"/>
</contents>
<subTabs>
    <subTabBar selectedIndex="${ui:defaulting(sessionScope.subTabIndex, '0')}" id="subtabbar">
      <contents>
        <link text="Link1">
          <primaryClientAction>
            <firePartialAction event="link1" targets="subtabbar message"/>
          </primaryClientAction>
        </link>
        <link text="Link2">
          <primaryClientAction>
            <firePartialAction event="link2" targets="subtabbar message"/>
          </primaryClientAction>
        </link>

Problem with file handles : jdeveloper makes them getting smaller

hello,
I downloaded today jdeveloper 11.1.2.1 for linux and I installed it on my centos 6.2 (like redhat).
I didn't read the prerequisites.
the installation worked fine, but when I tried to modify the JDialog swing file of a view project, I have an error message telling me there are save file errors, and complaining the files handles are too small.
I think the two errors are linked.
I read some stuff on the net and found a tutorial explaining how to have fs.file-max=70000 in sysctl.conf and 30000 when you type ulimit -n, what is also explained in the prerequisites.
so I ran jdeveloper a new time and found the same error.
I opened a terminal, and saw that ulimit -n gives ... 1024.
seems that the parameter is changed when I launch jdeveloper.
can you see an explanation?
thanks

Problems with Template JDeveloper 11g

Hi! I have problems with template in Jdeveloper 11g.
I had created jspx page from templeate:

</jsp:root>
THERE are error:
JSF page template at path /augiTemplate.jspx requires a model binding!!!
Why it is so an what it means? Pleas help!
Best regards!

Hi,
it means that your template has an ADF binding (PageDef) reference. When you create a page in the JSF page dialog and assign the template then the binding reference is created for you. You should see a bulb in the page source editor. Press it an it should create the missing binding for you

Installation Problem with APEX 3.1 on 11g

Hey,
I've a big problem with apex3.1 on 11g. Yesterday i wanted to install the new version, which i've downloaded from the oracle server. Furthermore i have followed the instructions by the documentation.
i executed:
1. apexins.sql FLOW_1 USERS TEMP /i/ Is that correct?
2. apxconf.sql
Do i have do remove the old version (3.0)?
Thanks for your help
Best Regards,
Andi

Hi Andrea,
I tried to reproduce this and could not.
I created a new 11.1.0.6 database on Oracle Enterprise Linux with character set WE8MSWIN1252. I even did this with an OS locale of Italian (and trust me, it was a struggle, as my Italian is about as weak as my German). The only thing that is different between my test and your configuration is the server OS.
I then installed APEX 3.1, tried it in browser language 'it' and 'en-us', but I could not reproduce the issue.
Can you think of anything atypical in your configuration, installation, or database parameter settings?
