Command_link generated by JSTL does not return value attribute
Since data_table CANNOT RENDER DATA IN SINGLE ROW, MULTIPLE COLUMNS, I am using the following to show the data as links in single row, multiple columns
<TABLE><TR><TD>
<c:forEach var="item" items="${MyBean.Filters}">
<c:set var="myLink" value="${item}" scope="request"/>
<h:command_link value="#{myLink}" actionListener="#{MyBean.LinkSelected}">
<h:output_text value="#{myLink}"/>
</h:command_link>
</c:forEach>
</TD></TR></TABLE>
The above JSTL shows up the links fine in a single row. But when a link is selected and the actionlistener is called, I see that the value parameter is null. Is this because the command_link is in a TABLE (i think I read somewhere that this is a known bug... )
I do
value = (String)((UICommand) event.getSource()).getValue();
to get the value...
I tried several ways.. all I need is a way to distinguish the links and know which link has been selected.
Any suggestions please....
The value is null when the ActionEvent listener fires, because the myLink variable is only available during processing of the JSP page as part of the Render Response phase, not in the request triggered by clicking on the generated link.
There's simply no way to get this to work using JSTL's <c:forEach> action, and it's not because we didn't try. A custom renderer for the UIData component that renders a single component as a table with one row with multiple columns (or whatever you need) is the only solution I can think of.

[Solved] ADF - Update does not return values generated by a trigger
Hello,
I'm using JDev 10.1.3.3.0 and DB 10.2.0.3.0.
On DB I've created a table, a sequence and a trigger:
CREATE TABLE TAB1
ID NUMBER PRIMARY KEY,
EDITED_AT DATE,
VALUE VARCHAR2(64)
CREATE SEQUENCE S_TAB1
INCREMENT BY 1
START WITH 1;
CREATE TRIGGER T_TAB1_BIE
BEFORE INSERT OR UPDATE ON TAB1
FOR EACH ROW
BEGIN
IF INSERTING THEN
SELECT S_TAB1.NEXTVAL INTO :NEW.ID FROM DUAL;
END IF;
:NEW.EDITED_AT := SYSDATE;
END;
/In JDev I've created an EO - Tab1, a VO - Tab1View and an AppModule.
In the EO Tab1 I have checked "Refresh After Insert" and "Refresh After Update" for Id and Edited_By attributes. I made the latter two attribures as "Never" updatable.
Then I test the AppModule with a JDev Tester (I use a connection which connects as an owner of the 3 objects above).
Then I insert a new row and enter a value into the Value field in the Tester. When I press Commit button everything works great - Id and Edited_By attributes get populated with values generated by the trigger.
But when I try to update the Value field and press Commit the Edited_By field does not retreives new value that was generated by the trigger.
Why does this happens?
Many thanks in advance.
Yerzhan.Frank,
I tried to set Refresh option on both, Value and Edited_At, fields but unsuccessfully.
Then I tried to do the following in SQL Plus:
SQL> insert into tab1(value) values('ddd');
1 row created.
SQL> commit;
Commit complete.
SQL>
SQL> select * from tab1;
ID EDITED_AT VALUE
1 27.03.2008 17:01:24 ddd
SQL>
SQL> declare dt date; val varchar2(64);
2 begin update tab1 set value = 'ddd' where id = 1 returning edited_at, value into dt, val;
3 dbms_output.put_line('txt = ' || dt || ', ' || val);
4 end;
5 /
txt = 27.03.2008 17:01:24, ddd
PL/SQL procedure successfully completed.
SQL>
SQL> select * from tab1;
ID EDITED_AT VALUE
1 27.03.2008 17:02:12 ddd
SQL>As it can be seen Returning clause of an Update statement does not return a new date, i.e. 27.03.2008 17:02:12, that was updated by the trigger, it returns an old one - 27.03.2008 17:01:24.
Frank, maybe the issue is in the Oracle DB? -
WB_RT_GET_JOB_METRICS does not return values
DB v 10.2.0.2
OWB repository/client v 10.2.0.3
A DB function has a call to the Control Center transformation WB_RT_GET_JOB_METRICS to extract and preserve the metadata of number of records inserted/updated/deleted in a DB table.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
1.
The control center transformation WB_RT_GET_JOB_METRICS does not return any values when used under the Post-Mapping Process(mapped to the DB function describe above) in a Map.
The input parameter ;Audit Id' to the Map is passed from a calling Process Flow. The following query is used to retrieve the Audit Id of the Map.,
SELECT execution_audit_id
INTO l_audit_id
FROM ALL_RT_AUDIT_EXECUTIONS
WHERE parent_execution_audit_id = P_AUDIT_ID;
And the retrieve l_audit_id is passed to the WB_RT_GET_JOB_METRICS transformation to extract the number of records inserted/deleted/updated with the execution of the map.
Gurus, please advice if the approach is appropriate to retrieve the number of records inserted/deleted/updated by the execution of the map. If not, any alternate method.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
2. The control center transformation WB_RT_GET_JOB_METRICS returns values when used in a standalone pl/sql block with the appropriate audit_id.
Is this because the metadata for the Map execution is complete, whereas in the earlier attempt, the transformation is called within the map using the Post-Mapping process.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
3. Since the option 1 did not return any value, tried other option of calling/executing a transformation(call the the DB function mentioned earlier) after the Map activity is successful in a ProcessFlow. Here, the transformation does not seem to be executing, any tips of correcting this issue.
Request the forum for some helpful tips to resolve the problem. TiA (Thanks in Advance) for the response.
Message was edited by:
user599655In a process flow, passed the pseudo variable to a transformation to run the WB_RT_GET_JOB_METRICS after the map execution. I am not sure if this is the best solution, but it worked for me.
Still trying to figure how to use the pre-defined transformation when working on expression.
Thanks. -
LOV does not return value to the base page sometimes
Hi,
I have created messageLOV type items. These LOVs do return value to the base page usually. We have a user in Uruguay who is trying to use the page which has the LOVs. He says the LOV takes a long time to return to the main page after he clicks on quick select and also the value does not get populated in the main page.
We have not been facing any such problem here in India. The LOV has been tested rigorously with no issues as such.
Can you please suggest a reason why such a problem is occuring? Expecting your replies soon
Thanks,
PriyaThiyaga, did you read the devguide or the tutorial ?
Can you please give me the inputs about the creation of LOV and it requires how many lov mappings as mandatory?
This is there in the devguideHow to identify the mapping fields of an LOV which is already existing in the base page to reproduce in a similar way and need to do a customization on top of it ?
Open the page XML and you can find the LOV mappings.Tapash -
R12: Supplier Banking Details - LOV does not return value
Hi!
I am having a problem when selecting a Bank for a supplier.
I click on the icon to open the LOV and search for the bank i want to add for a particular supplier.
When i click on the select button, the value of the bank name does not appear in the text box.
In another environment it works perfectly.
Please help..
VikHi Vik,
In R12, while defining the bank and bank accounts, there is a section called ACCOUNT OWNER and USE, where we specify that this bank can be used for which application for e.g. Payables, Payroll, Recievables and Treasury,
Can you please check that the above bank account is enabled for use by Payables application.
I am thinking that might be one of the cause , why the bank name is not available at the supplier level..
Thanks

UDF does not return value even though its underlying query does.
I have a User Defined Function which is supposed to return a scalar varchar(50) value. This is what I did:
ALTER FUNCTION [dbo].[zt_prc_fnNSNsFmNIIN_Get]
@NIIN varchar(5),
@PN varchar(20)
RETURNS Varchar(50)
AS
BEGIN
-- Declare the return variable here
Declare @NSN varchar(50)
Set @NSN = (SELECT Convert(varchar(20), RTRIM(NSN.FSC)) + Convert(varchar(20), RTrim(NSN.NIIN)) NSN
FROM TechManual.dbo.ANSNS NSN
JOIN TechManual.dbo.AITEMTABLE AIT ON NSN.PRIMARYPARTNUMBER = AIT.PRIMARYPARTNUMBER and NSN.DODIC = AIT.DODIC
JOIN TechManual.dbo.PARTNUMBERS PN ON AIT.PRIMARYPARTNUMBER = PN.PRIMARYPARTNUMBER
WHERE NSN.NIIN = @NIIN AND PN.PARTNUMBER = @PN)
RETURN @NSN
END
However I keep getting a Null as the return. So I ran a test to call the function and run the the underlying query like this:
Select dbo.zt_prc_fnNSNsFmNIIN_Get('015132378', '850AS911')
Declare @NSN varchar(50)
Set @NSN = (SELECT Convert(varchar(20), RTRIM(NSN.FSC)) + Convert(varchar(20), RTrim(NSN.NIIN)) NSN
FROM TechManual.dbo.ANSNS NSN
JOIN TechManual.dbo.AITEMTABLE AIT ON NSN.PRIMARYPARTNUMBER = AIT.PRIMARYPARTNUMBER and NSN.DODIC = AIT.DODIC
JOIN TechManual.dbo.PARTNUMBERS PN ON AIT.PRIMARYPARTNUMBER = PN.PRIMARYPARTNUMBER
WHERE NSN.NIIN = '015132378' AND PN.PARTNUMBER = '850AS911')
Select @NSN
As you can see the Select statement is exactly what is entered in the UDF. However the call to the UDF yields
null
and the call to select the variable populated by the query yields "1377015132378".
Everyone here has taken a look at the UDF and are unable to see anything which might be an issue.

Regards,
Yerzhan.you need to explicitly include the column in your UPDATE statement SET clause that you expect to return the result you want it to be. here's what i think what happened even though you have a trigger the first statement that was processed was your update statement. at the time of the update it has to return the current values to the returning clause that is the values on the table. now comes next the trigger which gives edited_at column a new value. when the trigger got fired the process don't return anymore to the UPDATE RETURNING statement. it's like each sequence of codes does not executes in parallel.

LOV does not return the value (2)
PPR in general does not work correctly if invalid HTML is generated. One example of an invalid HTML is having an opening <TD> tag immediately following another opening <TD> tag.
After checking everything else, if LOV still does not return the value, test whether it's not a problem with the invalid HTML by placing the messageLovInput outside of the complicated layout nestings you may have. If it works outside of the layout nestings, look for the possible problems in the layout nestings.Hi RamKumar,

Hi guys
Trying to run this package on SQL 2012 agent and getting below error . No more details I could find so far.
The step did not generate any output. The return value was unknown. The process exit code was -1073741819. The step failed.
About Package - Its connecting to different version (2000,2005,2008,2008R2,2012) servers and putting Jobs information into one Database table.
Any workaround or fix ?
Thanks

MessageChoice does not return correct value
Hi
I am problem with MessgeChoiceBean's improver beharior
For the first time it retunrs blank and subsequently In one page if I select Yes, it returns No.
In another page it does not return any thing for the first two selections. And I reciev flip values.
I ran VO outside, VO is returning correct values.
MessageChoice attributes and associated PPR:
Data Type: Varchar2
Initial Value: N
Pick List view Definition: oracle.apps.xxx.docs.common.lov.server.YesNoVO
Pick List View Instance: YesNoVO3
Pick List Display Attribute: Meaning

String newLocationFlag = pageContext.getParameter("newLocationFlag");
Serializable[] parameters = { ""+newLocationFlag};

I have quite a bit number of columns to change render property.
Any help will be appreciated.
Thanks
PrasadYour question is not clear, are you saying the values in the messageChoiceBean is not displayed properly. As far as I can see from the definition the poplist picks the values from a lookup(Yes, No) values and has a PPR action associated with it. Did you check what this method handleNewLocationFlagChange is doing in the AM ?

Moonis Tahir MVP SharePoint,MCTS SharePoint 2010/2007, MCPD.net, MCSD.net, MCTS BizTalk 2006,SQL 2005Hi,
According to your post, my understanding is that you want to get the user name of the people picker control.
To get the user name in the people picker control, we can use the SPService to achieve it.
There is a function called
SPFindPeoplePicker , we can use this function to get the display name.
There is an article about this topic, you can refer to it.

Very Very Urgent Issue: Restricted Key Figure does not return any data
Hi all,
Please help me solving this urgent issue.
created customer exit variable on characterstics version and also
other customer exit variable on Value type.
I coded that in variable exit. Problem is when I include these in
restrickted keyfigure My query does not return me any data.
But if I remove from restrickted key firgure and put it as normal
charaterstics I see the variable is getting populated.
Also in RSRT the SQl generated when these are included in RKF is not
correct.
I debugged and know they are getting populated. As when included in RKF
I can also see the values of customer exit variables from information
tab.
I also know that there is data in cube for those restrictions.
I posted one OSS Notes regarding this urgent issue. But got no reply from SAP.
