** Wonderland apps flag day! **
I've committed changes to the PDF viewer and whiteboard applications to support window geometry and position synchronization. Until today, if you moved, rotated or scaled one of these apps, other users would not see the changes. Now they will.
This is a flag day because this feature requires a change to the WFS property files for these apps. You need to specify a new property "clientClassname" in the "cellSetup" section of the WFS properties file.
Here's the one for the whiteboard:
I've updated the sample WFS files for both apps. You can find them here:
If you do an update of your source without changing the WFS property files, you will get exceptions loading these cells. So make sure you update your WFS files for the whiteboard and PDF viewer apps. Note that thae WFS file for the whiteboard in the default MPK20 world has already been updated, so this issue only applies to apps that you've added to the world.
