Hi to whom it concerns.

Working with Spec (Pharo 4.0) I needed to dynamically update the ButtonModel BalloonHelp. Since it did not work, I searched and found that ButtonModel initializes helpHolder again thus removing the changeBlock set in AbstractWidgetModel.

The statement < helpHolder := nil asValueHolder. > in ButtonModel>>initialize has to be removed.

Since I do not yet work with Pharo 5 I propose that somebody working with Pharo 5 would fix this.

Hi Hartmut, Thanks for your report. Could you add this to our issue tracker https://pharo.fogbugz.com/default.asp?W41 and hopefully could you include some code in the form of a test that fails before your change and succeeds afterwards (like checking whether the value of helpHolder is nil or not) cheers -ben
