First of all I would like to describe the situation(some code will be added afterward): so we have some edit form of EnterpriseObject it have backing bean EnterpriseObjectBean, on this form we have some fields and one of them (LegalPerson) have LOV, this LOV is a Dialog which shows a Datatable with LegalPersons, so the point is to select a LegalPerson from this LOV. We have some thousands of legal persons so we must implement some searching possibility to find one we need, so we added simple field and button to search. Here we used same backing bean that is used for main LegalPerson form(LegalPersonBean). So after we make a search from LOV we have ArithmeticException - / by zero, but if we make search from LegalPerson list form we don't. Operations are very similar...
