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

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

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.
Just write in the when validate trigger
declare
v_status number;
begin
select count(status) into v_status from table;
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.

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.

Problem in using when-validate-trigger

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;

How to use when-validate-item in the form personalization?

Dear all,
I want to use when-validate-item trigger in the form personalization on a specific item. while in the same time the when-validate-item is not included in the trigger event list.
Please advice & Thanks in advance
Ashraf Ashour

Use condition. If you are validating a record, just out the desired check in the condition field for that specific item.
Thanks

ELSE

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 prohibit 'when-validate-item' to be executed...????

Hi ,
I have written 'when-validate-item' in a text item. I want this code not to be executed only in one and only one circumstance . In my form , i don't want it to be executed when a button is pressed...
The problem is that this item has the focus .. so presumably whatever i try to do -go to another item , press a button , e.t.c.- this code would run.....!!!!
How can i achieve this ...???
Thanks , a lot
Simon

Does the user press this button before or after navigating to the item? If before, then set a global variable when the button is pressed and just read the variable before executing your validation code. If after, then I think you may want to rethink your design. For example, you could turn off validation as the default until some other event occurs.

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.

When-validate-record trigger only if a non database item is changed

Hi,
I am trying a code in the when-vaidate-record trigger in the BLOCK level.
The trigger should fire only if a checkbox item value is ticked(Value ='Y) for the present record(i.e, if already existing other records have a value ticked (='Y), it doesnt matter and trigger shouldnt fire)
Please help me achieve this :
The code I have tried in when-vaidate-trigger, which does not work as what I want :
DECLARE
X NUMBER;
BEGIN
if
nvl ( :DEFLOC.to_be_defaulted, 'N' ) = 'Y' and :DEFLOC.COMMENTS is NULL
and :SYSTEM.RECORD_STATUS ='CHANGED'
     then
    set_alert_property(
         'err_alert',
         alert_message_text,
         'You must enter a comment when defaulting localities.');
          x := show_alert('err_alert');
          RAISE FORM_TRIGGER_FAILURE;
          end if;
END;The above code does not fire at all..
If I remove the part,
and :SYSTEM.RECORD_STATUS ='CHANGED'
it fires for "all records"(not just the currently changed records) where nvl ( :DEFLOC.to_be_defaulted, 'N' ) = 'Y' and :DEFLOC.COMMENTS is NULL
Please help !!
Note: :DEFLOC.to_be_defaulted is a non database item ; :DEFLOC.COMMENTS is a database item

Hi kriti,
There is one more way,
In the when-checkbox-changed trigger,
if :your_chk_box = 'Y' then
set_Record_property(:system.cursor_Record, 'your_blk',status,changed_Status);
else
set_Record_property(:system.cursor_Record, 'your_blk',status,Query_Status);
end if;
Then it is easy for you to find out the changed records using get_Record_property((:system.cursor_Record, 'your_blk',status)
Hey let me ask you one Question, is that check_box item is database item ???
If so,
it is easier..the fol. code will work for that
if   nvl ( :DEFLOC.to_be_defaulted, 'N' ) = 'Y' and :DEFLOC.COMMENTS is NULL
and nvl(get_item_property('DEFLOC.to_be_defaulted',database_value),'N') = 'N'      then
                  set_alert_property(
         'err_alert',
         alert_message_text,
         'You must enter a comment when defaulting localities.');
          x := show_alert('err_alert');
          RAISE FORM_TRIGGER_FAILURE;
          end if;otherwise
If your are creating that temp. item, it should be in the same block as non-db item.
I will explain this... You are setting the status of to_be_defaulted check box of some queried record to Y based on some conditions, right?
These records anyways are not updateable. Now your requirement is to find out the newly checked check boxes.
So in the post query or the place where you set to_be_defaulted as 'Y, we will default the new item with value Y, so that in the when validate trigger, you
know which record needs to attacked, It is those records with nvl( new item ,'N') = 'N' and to_be_defaulted = 'Y'...

Dora...
