CanvasItem.addShowValueHandler() not fired when on ValuesManager

[michalg]

SmartGWT 2.5 LGPL, FireFox 3.6

There is a CanvasItem on the DynamicForm. The DynamicForm is a member of the ValuesManager.
ValuesManager gets data through a call to the editSelectedData(ListGrid).
The problem is that CanvasItem.addShowValueHandler() is not fired then user selects record on the ListGrid.
The very same handler is fired when DynamicForm directly (instaed of ValuesManager) gets data from the ListGrid.
Kindly please see standalone case below:

Setting 'shouldSaveValue' to true on your CanvasItem will resolve this.
One of our engineers is looking at the framework to determine whether there's a framework bug to address here.

Confirmed that CanvasItem.setShouldSaveValue(true) works as workaround.
