Who wants to guess what is the cause of this error with the below markup:


<ExtendedAdvancedDataGrid ...

dataProvider="{getHosts_pagedResult.lastResult}" ...

           columns:SelectAllAdvancedCheckBoxHeaderColumn width="15"

           ... (more columns here)


If you figured it out, kudos for being able to read the compilers mind :-)

The issue is the missing declaration of the columns tag.

<grids:ExtendedAdvancedDataGrid ...

dataProvider="{getHosts_pagedResult.lastResult}" ... >


            <columns:SelectAllAdvancedCheckBoxHeaderColumn width="15"/>

           ... (more columns here)



 If only the compiler spoke the same language as we do :-)
