Hi there,
Why are multi-line Text fields always displayed with 1 line height when it
is used within a section contained by a form that uses a TableWrapLayout
in conjunction with TableWrapData?
However, if the form uses GridLayout + GridData, then the Text is
displayed with the correct 3 or 4 lines height. Please snippet below.
Thanks in advance!
