Focus on input field when using two UIBB forms

In most of my UIBB forms I use the get_data method to set the focus to some specific input fields (using io_extended_ctrl). It works fine but for two cases:

1. when I have two UIBBs and I want to switch the focus from one to the other one. Though io_extended_ctrl->request_focus_on_field is not called in the first but only in the second one, the focus does not switch to the input field of the second form.

2. when a message is reported using the fpm message manager, the focus cannot be set to any input field.

Maybe some of you know a solution for these two problems?

Best regards,

Thomas
