> Hi all, I have Line Component in a Template which I would use the Visible Property depending of a two tag where path changes dynamically. Planning to use an expression like: Visible if {…/TTP01/…} AND {…/PPT01/…} where TTP and PPT are between 01 to 20 I tried to use Indirect Tag Binding, but this doesn’t allow me to have more than one tag. Another solution was to use Expression Binding, but this doesn’t allow me to have dynamic reference or I don’t know how. How to solve it? thank you for…
