i debugged the toColumns Mehtod and found the reason for the nullpointer. the
formulaTemplatesByPropertyPath map doesnt contains an entry for
"orgCategory.comp_id.companyId" which is the, as formula, mapped column.
in my opinion the bug is in the initPropertyPaths method. the "if (
type.isAssociationType() ) {" section never checks for formular columns
