[news.eclipse.pde] Unable to view source code from 3.4 "target"

[Will Horn <will.horn@xxxxxxxxx>]

Hi,

I am developing an RCP application using PDE and I upgraded my target 
platform to 3.4M5.  The IDE is still 3.3.2 (maybe this setup is 
unsupported?).

When I do this, I don't get source code for most Eclipse plugins (even 
though the source plugins are in the target).  There are a few 
exceptions, for example EMF source still shows up.

If I open a new workspace using a 3.4M5 IDE and point to the same 
target, all the source is available.  Must I use 3.4 version of Eclipse 
IDE/PDE to develop against a 3.4 target?

Thanks,
Will
