before i write my issue just a remark: i find gxt a great lib!
i have a general question to the implementation of gxt :
why most member data is kept private?
this makes me copy/paste code... duplicate and duplicate class by class.
ComboBox ... in initList() you create a PagingToolBar. i cannot override or customize it as it is not created in overrideable method. i cannot access it. i cannot even override the initList() as it is worthless without getting access to the members.
at least members should be kept protected to allow workarounds.
sometimes i think on copy the source of gxt into the project and replacing all private to protected :-)
thanks for your efforts!
