Hello,
I'm fairly new to Form Builder and I experience following problem, which I can't seem to figure out.
So, I want to use my form only for query-functions.
When one enters the form, he can look up records either on Companyname or on Projectname. Therefor I have provided 2 buttons who pop-up a LOV. After eitherone is selected, the query has to be executed. There is a Master-Detail relationship between Company and Project.
My plsql for the company button:
declare
v_show_lov boolean ;
begin
enter_query;
v_show_lov := show_lov('LOVFIRMA');
if not v_show_lov then
message('selecteer een firma');
raise form_trigger_failure;
end if;
execute_query;
end ;
Plsql for the project button:
declare
v_show_lov boolean;
v_get_value number;
begin
v_show_lov := show_lov('LOVPROJECT');
if not v_show_lov then
message('selecteer een project');
end if;
v_get_value := :PROJECT.CCODE;
--v_get_value := name_in('CCODE');
go_block('FIRMA');
:FIRMA.CCODE := v_get_value;
execute_query;
go_item('contract.projcode');
end ;
The first button only works when I go manually in Querymode first (by pressing F11). So I reckon my enter_query doesn't work? The property 'Fire in Enter-Query Mode' is Yes.
The second is a different story.
When I press it in non-query mode. It just fills in the LOV-values and the CCODE from company. It doesn't execute the query (probably because there is no enter_query).
When I enter query mode, the focus changes automatically to Company. And the LOV doesn't appear.
I have tried placing the enter_query on different places, just as the go_block and clear_block things, but there is always something wrong.
Hope you can help me!

Maybe you don't really need master-detail here. As, obviously, both LoV items exist in a detail block, create a single block, let user enter any item combination (including your 2 LoVs) and fetch data. It would be: push ENTER QUERY, enter item values, push EXECUTE QUERY.
As of your question: don't code ENTER_QUERY (except, for example, if you want to enter query mode when the form starts up) because, as Forms gets to ENTER_QUERY, execution is stopped and it awaits for user's input. So, if you want, you could ENTER_QUERY in WHEN-NEW-FORM-INSTANCE trigger, let the user choose value from a LoV and then push the EXECUTE QUERY button (on the standard Forms' toolbar).
If you insist (i.e. don't want to use built-in querying functionalities), set detail block's item values in a PRE-QUERY detail block level trigger.
Basically, you shouldn't code much here as Forms querying mechanism works extraordinary well. Just let Forms do its job.

Assigning values to items and expecting those values to be used in a query only works if you're in enter-query mode.
If you're in enter-query mode go_block doesn't work.
Maybe it'd help if you explained the relationship between the blocks.

And that means what exactly?
I'm begining to feel like I'm pulling teeth here.
I'm trying to get a proper description of what you've got and what you're trying to do so I can suggest a way to make it work.
Do I really need to prompt for every single detail?
