Hi, I am playing with ComboBoxBase class - I derived another class that uses "transform" property to transform existing combo box to Ext one.
I found a problem with MinListWidth: Specified cast is not valid in ClientConfig line 409
Unit defaultVal = (Unit) defaultValue;
and defaultValue for MinListWith is [DefaultValue(70)], while for other Unit properties in another classes (looking into the source code) there is [DefaultValue(typeof(Unit), "XX")].
