TP4 Lov and application module procedure

Question

Hi!
I have a little problem. I have a page with a LOV and a Task Flow.
In the Task Flow i have a table, wich depending the value that users select in the LOV present some data. (Whith where clause and a bind variable).
This works ok. But when I add to the task Flow a button that invoke a procedure implemented in the application module. The result, is that the LOV doesn´t work. i mean not appear the data to select.
Any idea?
Thanks

Answer 1

Ok my english....
First what a want to do:
I´m doing a create,update,insert,remove page, using adf rc. But for doing those, I need to use PL/SQL procedures, not the create, remove.. procedures that jdev gives us in the data control. And as the table has a lot of records i ´ve put in the page a LOV to search the rows that the user want to modify.
Now how i do that (in short):
First i "programmed" the LOV. I´ve created a ViewObject for the lov and another view object for the table the second VO has a bind variable and a where clause.
"Where tabla.cod = :LovParam"
For passing the value from the LOV to the table i have defined a Task Flow View with input parametre, with a panel collection and inside the table VO. have defined an executeWithParams binding and invokeAction executable.
I´ve drop the task flow to the .jspx.
In the .jspx I´ve inserted a LOV component and create a variable executable a inside of this a variable. And then i´ve bind the LOV with the variable.
Probably here is missing a step, but how i say up this is in short what i have done.
Finally all this works fine.
The second step is to add the command button that calls the PL/SQL, for doing this:
I´ve programmed in the application_module_implementation a function which calls the PL/SQL, I´ve followed the steps that are explained in the adf guide, in chapter 25.5.2 Invoking Stored Procedure with Only IN Arguments.
And then i´ve dropped the function from data control to statusbar facet of the Data Collection.
The result is that when the button is on panel collection, the LOV does´t work. And if remove the button the LOV works. This haven´t any sense for me.
I have made more test and, if instead of the panel collection I use a form layout the LOV works but the button gives me the next error "Not supported function".
I know that this is another think. and now i´m trying to solve this one.
I hope now you have material to work with. I think that it´s strange what happens with the collection panel. And about the function sure that i´m doing something wrong.
Thanks, for you interest
