On a form I have 2 blocks, shown on different tabs. Relation created by forms wizard. The relation works great when navigating through the blocks, the details for the master are shown fine.

Example for this form is master block is a type of food. Detail block is list of ingredients.
When creating a new type of food, if it's = CAKE we insert records based on a select on another table into the ingredients table.
Else, the user has to manually create the ingredients.

Upon commit of the form on master block (must be saved to enable detail block tab), the ingredients are not displayed but are there. If I execute query by hitting F8, the records are present.

Why is the populate-details trigger not being fired or what am I missing?

I assume the insert of the child records is done from a trigger in the form?
Simple answer - because the form has no idea you've just made it insert child records for the newly inserted master.
Normally when you enter a new master there are no children, so why would it try to populate the block with records that shouldn't exist?

That's what I thought as well.

If that's so, you could try to run the POPULATE-DETAILS trigger manually (either using EXECUTE_TRIGGER or simply by copy/pasting POPULATE-DETAILS code into your own trigger (you'd put it after the INSERT statement)).

Thanks for all of the feedback. I apologize I am now just getting back to this. I tried the manual execution by populate-details and did not have success. Yes the detail records were inserted by a trigger. In the end I had to clear the form on commit and take the user back to the key block allowing them to see the master id of the record and navigate back through to see the records.

While not the ideal solution it will have to do for now.
