Description Pascal Rapicault CLA 2003-09-03 15:56:22 EDT 
The core team is about to offer support to change the workspace dynamically.
The envisionned solution without the new runtime is to return a special exit 
code and do something special to restart. 

However, with the dynamicity and the new runtime we should able to do better.
Any thoughts are welcome.
Comment 1 Jeff McAffer CLA 2003-09-10 14:56:08 EDT 
A couple of things to note/remember.  
- the workspace is not just for resources.  It is the data area for plugins (I 
don;t mean the metadata but rather plugins are free to discover the locaiton of 
the workspace and write whatever user files they want there.  Or not.
- not all scenarios require/want a workspace.  Various RCP scenarios explicitly 
don't want one because they have nothing to put there.
- changing the workspace is something for which plugins need to be prepared.  
Assuming the workspace contains resources, various plugins could have resource 
objects.  This are implicitly specific to a particular workspace.  When the 
workspace is changed, these handles must be invalidated.

Suggestions:
- add lifecycle (where?) to say that the workspace is/has changing/ed.  
Interested plugins would listen and do the right thing.
- plugins which use the workspace but do not listen are either legacy or 
misbehaving.  The only reasonable way to handle them is to restart them.
- plugins must explicitly declare that they are able to handle dynamic 
workspaces.  When the workspace is changed, dynamic enabled plugins are 
notified.  Non-enabled plugins are restarted.

Unclear if this effort is still going forward.  Will leave open pending 
discussions with the Core team
