Problem with when validate trigger

Hi All,
I am using oracle forms 10g.
I have developed a custom form In that i have two block Header block and Detail block.In the header block some fields like Po number, po amount , supplier name, supplier site etc. And in the detail block i have po line details.
I have written a validation trigger under supplier name and supplier site, IF block.supplier_name is null then
message('enter supplier name') same under every field.
Now when the user enter po number it will go to po amount field and now when the user press tab it will go to the details block and query all the po related line,so i have written key-next under po_amount go-block and my code, Its works fine and giving the correct output. But the problem is When validate trigger fires when i press tab in PO Amount fields, Once i press ok it going to details block and querying.
Can any one explain me what i have done wrong. The validation trigger is firing and giving message.
Regards

But the problem is When validate trigger fires when i press tab in PO Amount fieldsSo, i'm not getting you..
Can you clear it any more ? or any other way..

Issue with When Validate Trigger firing multiple times

Hi guys,
I have Designed a Form Personalization on a Form which Fires a concurrent Program (built in:execute Procedure) when a Record is Saved.
Below are the issues I am facing:
1.Concurrent Program is Firing Multiple Times after Saving the Record.
2.2 input Values to Concurrent Program are passed as NULL though I have Data but they are in Different Block of Form.
Note :I have When Validate trigger on 1 Block but i am trying to pass 2 Values on Another Block as input parameters for Concurrent program.But those values are getting as null when program fires.
Thanks.

Problem using when-validate-trigger

Dear Experts,
After validating a item value, I want to navigate to a specified item besed on that item value. If i use go_item('item1') in when-validate-trigger, error comes, beacuse we cannot use restricted built-in go_item in when-validate-trigger. If i use key-next-item on 'item1' for validating item value then while navigating through mouse it does'nt fire.
Please let me know which triiger i should use?
Thanks
Abhishek Rustagi

There is no easy way to do this, however you could create a timer in your when-validate-item trigger which expires immediately, and place all of your navigational code in the when-timer-expired trigger - this way you could check the value which has been entered and navigate accordingly.

Hi, the way I use to solve this problem is using both: key-next-item and when-validate-item. In the w-v-i you make the validations you need (this control mouse navigation) and in the k-n-i code write:
-- first validate the values, to avoid invalid values
execute_trigger ('when-validate-item');
-- if trigger fire corectly then you can go to the item you want..
if my_item = 'A' then
go_item(my_next_item1);
elsif my_item = 'B' then
go_item(my_next_item2);
end if;

Experiencing problems with workflow- validate step

I am experiencing problems with workflow->validate step in Hyperion FDM.
I am not able to export unmapped dimension members to Excel.
Earlier everything worked fine.
But now all of a sudden it has become a serious problem.
when I click Export to Excel,processing starts and it's never coming to an end.
Every thing is getting stuck up.
Could any one suggest solution to this as it is delaying my deliverable.

Try opening excel first, then doing the export from FDM.

WHEN-VALIDATE-TRIGGER trigger looping so many times

Hi,
Below is the code written in WHEN-VALIDATE-TRIGGER trigger and after raise FORM-TRIGGER_FAILURE
the process is not stopping and the trigger message looping without end when

When validate trigger forms 6i

Please help me to create when validate item trigger.
There is one table "job" - id, status
status is X or null. i want to do in forms. when someone is entering value for id, it should check first the status for that id in job table status field.
if status is null then it should show msg "this id is already open for another job"
Edited by: only.ashish99 on Dec 26, 2012 1:44 PM

Hi,
So You mean that if the user dosent enter the staus then u need to show a message and if the entered status is there in ur table and then u need to show a message.

If :Block.field_name is null then
message('');
Else
If v_status=0 then
ur action
else
Message('this job is exist for another');
End if;
end if;
End;
Try this.

Issue with WHEN-VALIDATE-ITEM trigger in Forms 6i

I am working with a form(A) which displays a modal window(B) with some database fields on it when a button on the form was pressed.
First as soon as I pressed the button on the form A the modal window B appears with the values as (for example)
Scenario - 0
field 1 - OTHER
field 2 - 123-456
field 3 - 14-JUN-2006
field 4 - Old Contract
Scenario - 1
If field 1 is changed/updated to a value NONE then the remaining fields should grey out and should not allow the user to edit/update those fields. Also it should clear all the data in the fields and should display only blank fields. Now the only updatable field in this case is field 1 which has value NONE at this moment.
field 1 - NONE
field 2 - NULL
field 3 - NULL
field 4 - NULL
Only if the user exits the modal window B and clicks on SAVE button which is on the form A then only the data changes are committed to the database tables.
At this moment I don't want to exit the modal window B which means the data changes are not yet committed to the database.
Scenario - 2
Now if field 1 is again changed/updated to a value ANOTHER then the remaining fields has to be populated accordingly using the values from the form A and B and it should allow the user to edit/update the remaining fields in window B.
field 1 - ANOTHER
field 2 - 123-456
field 3 - 14-JUN-2006
field 4 - Old Contract
Now if you observe Scenario - 0 and Scenario - 2 only field 1 is differing. Rest of the three fields are same. As I didn't exit from the modal window the changes were not committed to the database.
If the order of the scenarios is like below:
Case1 : Scenario - 1 & Scenario - 2
Case2 : Scenario - 1 & Scenario - 0
I am able to successfully handle the above two cases as initially the three other fields are set to NULL and the user will be able to update the data and can commit the data.
If the order of the scenarios is like below:
Case3 : Scenario - 0 & Scenario - 1
Case4 : Scenario - 0 & Scenario - 2
I am also able to successfully handle the above two cases as finally the three other fileds are set to NULL and the user will be not be able to modify them and obviously NULL values will be stored in the database when committed.
Now the problem is with the following order.
Case5 : Scenario - 0 & Scenario - 1 & Scenario - 2
Case6 : Scenario - 2 & Scenario - 1 & Scenario - 0
In the above cases we can successfully handle until Scenario - 1 but when comes to Scenario - 2 how can we be able to display the data as shown.
I have tried to perform this using WHEN-VALIDATE-ITEM on field 1. When the field 1 is changed from OTHER to NONE I have assigned NULL to the remaining fields. So it's working fine as I mentioned earlier. Now if I change field 1 from NONE to ANOTHER its allowing to update the remaining fields but its not populating the data.
Can anyone help with this?
Thanks for the patience in reading the problem....

Yes, if you use the debugger as Gerd said you can get and see the data as the code executes line-by-line. You can also use message statements in your code to display the data.

end if;
end;when-validate-item trigger raised unhandeled exception ora-01403
Thanks And Regards
Vikas Singhal

Hi,
Probably your first select statement itself throwing the error - ora-01403
So may be try to include an exception part for your code, to catch the exception ora-01403 -no data found
and there display the messgae- 'Please check the Order'.
Hope it will work then

How to invoke when-validate trigger

Hi all ,
I just want to know how can i Invoke when-validate-item trigger of another item by without navigating to that item.
Exampls. I have two items A and B
I want to invoke item B's when-validate-item trigger by keeping the focus on A or being in A .

first: write procedures for each when-validate.
e.g. WVI_name_of_the_item_A and WVI_name_of_the_item_B
then you start this procedure in item A and the other in item B.
now you can use the validation-procedure of B inside the validation of A
try it

When Validate Trigger is getting executed when Execute_query

i have a data block in which i have 2 text item. i have defined when validate item.
when the form is starting up i have given execute_query. before fetching the values my when validate item is getting executed. i dont want to do this. can one help me out in this case

Hi,
Can you pls. check any initial value is given or not? Otherwise for quick solution you can declare a parameter upon which when-validate will validate the value. You can change value before and after 'EXECUTE_QUERY' statement. This is not a good idea.

Problem with WHEN-CHECKBOX-CHANGED and ON-POPULATE-DETAILS

I have a detail block with a relationship set up to a second block. In my first block, if I cause an error but the next action I take is to press a checkbox on another record, my error will display and the raise form trigger failure is triggered but the checkbox changes it's value and the cursor is displayed on the record with the error. I didn't want the checkbox to change if an error occurred. I tracked this through the trace and saw the on-populate-details is fired between the error and the when-checkbox-changed trigger. I went through debug and saw because of the erorr, the system will do a 'return' back to the sending action. I beleive this return is causing the when-checkbox-changed to fire. I'm just guessing here. I tried a similar action on another form without a relationship set up. That would eliminate the on-populate-details trigger. When I did a similar error, I got exactly what I was looking for. I caused the error but pressed the checkbox on another record. The error displayed but the checkbox did not change and the cursor returned to the error record. I need the record to have this relationship. Consequently, I need the on-populate-details trigger. Can anyone think of a solution? I'm currently on Forms 6I. We are going to forms 10G in the next few months. But I really need a solution on my current set up. Thanks.

The getNextDatabankRecord() call is at the beginning of my run code. I use one step just for this line code.
Code :
public void run() throws Exception {
          beginStep("CHARGEMENT DES DONNEES SUIVANTES");
               info("Chargement des prochaines données...");
               getDatabank("NouvellesIA").getNextDatabankRecord();
          endStep();
Stop the user after this step and goto the finish section should not be a problem...
If I use the "When out of records" option, does it jump directly to the finish section ?
Thanks,
Benoit.

Assuming IBM MessageBroker connects through OCI, setting the NLS_LANG variable in its environment to .EE8ISO8859P2 could help. You should also review MessageBroker's documentation, especially any configuration parameters for Oracle, to see if the character set is not configurable there.
