No navigable items in destination block [message #601499]

Good day.
I am getting the "No navigable items in destination block" error message on a form I am working on.

This form,"DETAILS" is being called by a main form called "CUSTOMERS". I access the "DETAILS" form by calling the form on a when-button-pressed trigger in the "CUSTOMERS" form.

Now, whenever I press the custom exit form button in the "DETAILS" form, which uses the code 'exit_form', I am getting the "No navigable items in destination block" error message in the main form "CUSTOMERS".

In the details form, there is no GO_BLOCK method. Can anyone please assist with this issue?

Thank you.

If you're getting the error in customers then it will be because of code in customers, probably whatever is after the code that calls details.
Code in details is irrelevant.

Below is the code used in the when button pressed trigger to call the "DETAILS" form. Is anything wrong here?

:global.u_cust_code := :cust_code;
:global.u_prem_code := :premises_key;  
:global.calling_form := 'CUSTOMERS';  
call_form('DETAILS');

How many blocks are there in the CUSTOMERS form? If more than one, what is the first block (i.e. the topmost one you see in Object Navigator)? If it is some control block with invisible or Display type items, that might be a reason , i.e. when you return, navigation goes to the first block's first enabled item. If there's none - it fails.

navigation should stay in the button I believe, unless there's other code to send it elsewhere.

As I said before, code in the detail form is irrelevant. The relevant code has to be in the same form that shows the error.
