[onthefloorr@xxxxxxxxx (Attila )]

hi There,
I have got a little problem in eclipse ganymede,
So i installed some plugins :
  - birt
  - svn (collaboration tools )
  - wtp
  - jdt
  - dtp
  - enabled features
  - mylyn 3.4
  - communications
  - gef
  - soa
  - spring ide
  - jbosstools dev release 3.0.0. beta 1

So when i installed jboss dev plugin , i found bug in updater, when i 
tryed install another plugin, i always got error message that is cannot 
complete the request :
Cannot complete the request.  See the details.
 Cannot find a solution satisfying the following requirements 
Match[requiredCapability: 
org.eclipse.equinox.p2.iu/org.objectweb.asm/[2.2.3,2.2.3]].

When i was uninstalling jboss tools dev plugin , it was work  again.

Other, so my real problem:
I would like to use my tempaltes in eclipse.
I opened a Preferences window when i was opening Java->Editor->Templates 
column, i received a pop up alert: Could not accept changes : The 
currently displayed page contains invalid values.
after this message i recieved an empty page with this text: Create edit or 
remove templates, but it havent got any b utton.
I dont know why do this.

Have anybody got  idea ?
