We've been plagued by the Custom Web Publishing XML bug (skipping <COL> tags for unpopulated portals) and had hoped that the 12.0.2 Server update would take care of the problem. After installing it, it's clear that it did not solve it for us.
After doing further testing, I noticed that the XML returned for both the FMPXMLRESULT and FMRESULTSET grammars list this:
<product build="03/15/2012" name="FileMaker Web Publishing Engine" version="18.104.22.168"/>
My Admin Console and the "start page" both list that FMS is "Current Installed Version: 22.214.171.124"
We have a one-machine deployment, so I had thought that the updater would take care of all components, but perhaps it's the update-installer that has the bug, and the WPE was not updated.
Is it actually possible that the updater didn't update the Web Publishing Engine component.... ?
