RCP 6.1: Creating Dynamic Toolbar Actions using MemoryFileSystem Problem

[Jordan Ganoff]

In an effort to dynamically create transient Actions on a per-login basis I’ve registered a custom MultiFileSystem that proxies a MemoryFileSystem. Action instances are predefined and only their shadow references are created dynamically as FileObjects at runtime – before the main window is visible. However, the references created for Toolbar Actions are not consistently added to my toolbar. This behavior is only exhibited by shadow references defined for a Toolbar. All other references: Menu, Shortcut, or otherwise; are consistently created, visible, and operational. I have been unsuccessful in reproducing the problem consistently – leading me to believe it could be a threading issue.

I am creating the toolbar actions as follows:

Look up a reference to the FileSystem.class. Create “Toolbars” folder from the root of the found FileSystem (my custom FileSystem). Then I create the FileObject for a toolbar action, setting all appropriate attributes for position, original-file, etc. This produces the desired file structure (when using the Default FileSystem to ensure everything is created as expected).

This is all done off the EDT. I’ve also tried on the EDT with no luck.

Could there be a problem of events not being fired that the Toolbar Displayer listens for? Any thoughts would be greatly appreciated.

Thanks in advance,
