Call pega function in control rule to format IBAN number for output.
The end result I want to obtain is the next:
An IBAN number is stored on the clipboard in internal format (uppercase, no spaces), where as on the screen, it is displayed as a formatted IBAN (uppercase in groups of four).
I created a function that takes "I" or "O" and the number to format the given IBAN to input/output format.
I use this function in an edit input rule to format the entered number for internal storage.
And I created a control rule in which I would like to call that same function to format my iban for output. But I can't figure out how I can call my custom function in the html/jsp-tab.
Any better aproach also appreciated :-)
