No, it is not related to spec, just the way the imagemodel adapter uses morphics click event for the action dispatching.
You can simulate the same (buggy) behavior on pure morphic:

|m|
m:= Morph new.
m on:#click send:#value to:[m confirm:'Really?'].
m openInWorld.

MouseClickEvent processing and modal dialogs don't work.

Sorry, I wrote it badly. Of course it is an issue of Morphic, thanks for your clarification.
So, is it a bug or it just works that way and it is supposed to do so by architectural design?

I think it is a bug on morphics mouse click handling.

The UI-element for a ButtonModel is a PluggableButtonMorph, it already has support for handling

"clicks", but it only acts on mouse up /(or mouse down)

An ImageMorph don't have this by default, so the ImageModel adapter installs a eventhandler with

on:event do:action and the creator of Spec choosed #mouseUp for the mouse event to act on.

The interesting thing is that with a button it works.

�� I have a weird behavior building an interface with Spec.

�� I have a window built with Spec, and I want to add a
�� button that shows a dialog with some text.
�� To display the dialog I use the following line:

�� UIManager default longMessage: 'a text message' title:
�� 'some title'.

�� And I hooked this code to a widget through the #action:
�� method.
�� The problem is: If I use a ButtonModel, the code behaves
�� correctly showing the dialog.
�� If I use an instance of the class ImageModel to display an
�� icon, the dialog is displayed but the interface "hangs",
�� in the sense that the "ok" button won't close the dialog
�� and every click would spawn a new dialog.

�� I would like to use an icon because it integrates better
�� with the interface.
�� Do you know if it is a bug or if I am doing something wrong?

�� Thanks,
