SmartClient Version: v13.1p_2026-02-03/Enterprise Deployment (built 2026-02-03)
Hi, I’m having an issue in my application that was quite hard to reproduce, since it doesn’t occur in the showcase. However, it does happen with the following test case:
Basically, the first time the second tab is selected, it appears empty. If I reselect the first tab and then select the second one again, the grid is shown correctly (the barGrid has the filterEditor) :
The issue does not occur if there are no visibleWhen conditions on the tabs, or if showFilterEditor is not set on the barGrid.
If I use enableWhen instead of visibleWhen, everything works as expected.
Another strange behavior: if I try removing visibleWhen only from the first tab, the first time I try to select the second tab it requires two clicks:
