In the following testcase i have a selectItem with an inputtransformer (in this case it's really trivial). Now when changing the value of this selectitem no change handlers are fired. Neither is form.getValues() updated with the new value of the selectitem.
This seemed to happen only when I defined the datasourcefields myself, and not when I loaded them from an xml datasource.
When I remove the inputtransformer, the events get fired fine and getValues() is updated properly.
This was tested on SmartClient Version: SC_SNAPSHOT-2010-11-15/PowerEdition Deployment (built 2010-11-15) with GWT 2.0.4 on firefox 3.6.12
