Re: [platform-ui-dev] Undo now available from task list, bookmarks view

[Susan M Franklin <susan_franklin@xxxxxxxxxx>]

In the code I just released, the relationship
is that as long as the resource containing the marker exists, and the marker
exists, then the undo is still valid.

File delete should eventually be undoable,
and that should bring back the bookmark, all as one atomic operation.  
My next task is working on undo of resource-level
operations.  I wanted to get something smaller out there first rather
than wait for the whole story to be there.

What is the interlock between creating/deleting markers, and manipulating
the resources [potentially] related to markers? 

Similarly, if I delete a file, I see that bookmarks for that file get deleted.
Will file delete eventually be undoable, and would that bring back the
bookmark?

Subject	[platform-ui-dev] Undo now available from task list, bookmarks view

I've just released code that supports undo of marker operations, such as
creating, deleting, and updating tasks and bookmarks. 
In tonight's nightly build and beyond (but not in today's I-build), you
should be able to undo these operations from both the associated view (task
list, bookmark view) as well as the package explorer or resource navigator.

I'd also like to encourage any plug-ins that define their own marker operations
to consider adopting this support.  I can help get you started, or
in some cases supply patches if I already understand your code.  The
API classes are defined in org.eclipse.ui.ide.undo.  They are marked
experimental for now. The basic idea for clients is that instead of calling
the core.resources API to create, update, or delete a marker, you instead
create an undoable operation (such as a CreateMarkersOperation, UpdateMarkersOperation,
etc.). that describes what you want to do.  Executing this operation
will perform the operation, catch and handle the CoreExceptions, and make
the undo for the operation available. 

Please see the following bug for more info, and open any new bugs on the
feature against Platform UI  with [Undo] in the title.
