The attribute table doesn't seem to refresh its tabs after being opened for the first time. When I launch the application, my experience is that whichever layers I have turned on in the "layer list" widget at the time that I first open the "attribute table" widget are the only layers that I will ever see tabs for in the attribute table.
For instance, my application has parcels and fire stations. If I turn both off, then open the attribute table, the attribute table is empty. Even if I turn both back on and reopen the attribute table, I can never get any content in the attribute table.
Now if I refresh the page, and I turn parcels on, then when I open the attribute table, I can see parcel attributes. However, turning on the fire station layer never makes that layer appear in the attribute table, even if I minimize or close, then reopen the attribute table widget.
If I refresh the page, turn on parcels and fire stations in the layer list before opening the attribute table for the first time, then I can see the attributes for both those layers in the attribute table.
Thanks for your help.
