EL Expression Builder to restrict withdrawal of certain absence types

Content

Hi

We require the ability to restrict the withdrawal of certain absence types through 'Absence Records' screen but are unable to figure out the correct syntax for the expression. We are trying the following BindingParams without success

#{bindings.AbsenceFilterStatus.inputValue

#{bindings.AbsenceFilterType.inputValue

For the above, unsure how the end of the BindingParam should be entered, for example for #{bindings.AbsenceFilterStatus.inputValue i have attempted the following without success

#{bindings.AbsenceFilterStatus.inputValue == 'Completed'} and also #{bindings.AbsenceFilterStatus.inputValue['Completed']}.

Any help would be appreciated.

Thanks
