The header on the PLACE screen in FSM 6u19 allows changing to a different label expression, but when the label result is longer than about half the screen, it is truncated.Our configured screen has only one visible button in the header (Save), so there is still lots of room left over to the right side.
As a guess, I have tried inserting a <label_percent> tag in the screen XML <header_def>, by analogy to the <column_def>, but then FSM automatically removes that tag upon saving. Directly entering a width for the whole panel doesn’t affect the fraction of space given to the label versus the buttons.
Is there a way to increase the horizontal percentage of this label?
