Tool <> WebDialog <> Observers relationship

def onCancel(reason,view)
  @web_dialog.close
end

Do you need to close the webdialog here? It does not stop the Tool.

If the tool is a line tool for instance, and the user starts to draw a line:
Clicks once to set start point - then the tool enters a state where it expects the user to pick another. but if the user hit Escape this event is triggered with reason == 0 - and the tool should then reset itself. But the tool itself is not killed.

@dlg.set_on_close { puts "Set on close fired." Sketchup.active_model.active_view.remove_observer ProperTool::get_view_observer Sketchup.active_model.select_tool(nil) }

Regarding Sketchup.active_model.select_tool(nil) - that will activate SU's Select tool. I'd recommend that you instead use Sketchup.active_model.tools's push_tool and pop_tool so that when you deactivate your own tool it return to the previously selected tool (which might very likely not be the Select tool)

It is just a single stage tool. If an user presses escape I want to close the webdialog and deactivate.the_tool. Invoking @dlg.set_on_close {Sketchup.active_model.active_view.remove_observer ProperTool::get_view_observer; **Sketchup.active_model.select_tool(nil)**} will close the tool... and will trigger @web_dialog.close again. That is why it fires up twice.
