Form hangs on error

Question

Hi,
I have a form with a normal block.
In one item, I have a When-validate-item, which calls a db-package. In their, an error is raised by qms$errors.show_message.
What happens now is that the form shows the error-window (without the errortext being visible, but thats something else), but then starts revalidating the item. So the form hangs, because he is constantly switching between the two blocks/windows/items.
Has anyone experienced the same?
Thanks
PS: I have a work-around but it don't like to use it.

Kristof,
I did experience the same behaviour.
From the When-Validate-Item a package procedure was called.
Procedure called a function, if the return value from the function returned false --> raise qms$errors.show_message.
Because the message was raised from the database the form will navigation to the error window.
This is being done with a go_block call, but you will return to the When-Validate-Item trigger.
Then the form will get in a loop.
The solution I used was to raise the qms$errors.show_message from within the form.
Instead of calling the package procedure, I called the package function.
If the return value of the function equals false I raise the qms$errors.show_message from within When-Validate-Item.
This way you won't navigate to the error-window and therefore the looping problem will not occur.
