Anything that interacts with the UI must be sent to the display
thread. You need to send a IDrawCommand, which is ran in the UI
thread. Or use getContext().getDisplay().asyncExec( runnable ).
PlatformGIS also has useful methods for interacting with the UI.

Hi uDiggers,
We are developing a tool against udig sdk rc14.
Its workflow is similar as the one of the InfoTool.
InfoTool:
User activates the tool->He interacts with the map-> A view is shown
with the
result.
Our tool:
User activates the tool and a view is opened->He interacts with the
map->Commands are launched-> Map has changed and as feedback, the
view is
updated.
The problem I'm having is that I can't update the view from the
command
because view and commands are on different threads. This is the
error I get:
org.eclipse.swt.SWTException: Invalid thread access
at org.eclipse.swt.SWT.error(SWT.java:3563)
at org.eclipse.swt.SWT.error(SWT.java:3481)
at org.eclipse.swt.SWT.error(SWT.java:3452)
at org.eclipse.swt.widgets.Widget.error(Widget.java:438)
at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:377)
at org.eclipse.swt.custom.CLabel.setText(CLabel.java:731)
...
..
.
I would like to know if there is a way for the tool to catch the
feedback of
the command, so I can know when the command has finalized its run
method.
Anyone can tell me if that is possible?
Cheers,
Aritz Dávila
