Hi,
SmartClient Version: SC_SNAPSHOT-2011-01-25/EVAL Deployment
I created this standalone test case, because I believe there are some issues with extending the CheckBoxItem and thus creating our own custom CheckBoxItem.
The initial value of the checkBox is not set correctly, it is always set to the default => "true".
The reason "why" becomes clear as the EditorValueFormatter and EditorValueParser are never called?!?
Something I find very strange, as my other custom editor types don't seem to have a problem with this, however, these other editors extend TextItem or ComboBoxItem.
On the other hand, the input transformer is called! However, as the initial value is not set correctly, my oldValue is a javascriptobject (which I expect it to be) but my (new) value is "true"and not the value after the change?!? In other words, I'm getting the default value from the checkBox iso the clicked event.
I also tried adding a valueMap, but that doesn't fix anything.
My biggest issue is that the formatter or parser are not called.
Please advice.
Regards,
Bart
