Tool.onCancel - Reselect tool?

1: the user re-selected the same tool from the toolbar or menu.

I can't seem to get reason code 1 to trigger. Only 0 and 2.
I thought I'd used it before - but I'm unsure.

Test snippet:

<span class="syntaxdefault"><br />class MyTool<br /><br />  def activate<br />    puts </span><span class="syntaxstring">"activate; #{self}"<br /></span><span class="syntaxdefault">  end<br /><br />  def deactivate</span><span class="syntaxkeyword">(</span><span class="syntaxdefault"> view </span><span class="syntaxkeyword">)<br /></span><span class="syntaxdefault">    puts </span><span class="syntaxstring">"deactivate; #{self}"<br /></span><span class="syntaxdefault">  end<br /><br />  def onCancel</span><span class="syntaxkeyword">(</span><span class="syntaxdefault">reason</span><span class="syntaxkeyword">,</span><span class="syntaxdefault"> view</span><span class="syntaxkeyword">)<br /></span><span class="syntaxdefault">    puts </span><span class="syntaxstring">"MyTool was cancelled for reason #{reason}"<br /></span><span class="syntaxdefault">  end<br /><br />end<br /></span>

Never got code 1 either. So I usually only test 0 or not 0

Is 1 (technically) possible?
Do "radio" toolbar buttons trigger an action if the current state is not changed?
Do toolbar buttons in the OS X version behave the same way?

You can click a menu or toolbar button that activates a tool. It does triggesr the action and activates the tool again, but it deactivates the tool instead of calling this event.

Are you dealing with a single re-usable Tool instance ?

Or does the command create a new Tool instance each time the menu item is chosen ?

Either way - I'm unable to trigger that event.

This seems like a documentation error. However when re-selecting a tool the deactivate and activate methods seems to be called right after each other so maybe comparing a timestamp can be used to detect when a tool is re-activated.

That's what I do, including for simulating a double-click on icon.
However, you cannot avoid the calls to activate() and deactivate(), just shortcut them.

I just realize that, should Trimble fix this issue, there could be some regression in my scripts, because I only test status 0.
