The problem i'm having in mendix is using the xpath constraint in the reference selector. I have 2 entities in my domain, Klant (customer) and Order. I use a reference selector to select the account number of the customer (Klant entity) and insert it in my Order data grid. In the order entity a customer can have 3 enumerations In_behandeling (being treated, default value) goedgekeurd (approved) and afgekeurd (disapproved). The customer must only be selectable by the reference selector if his order status is 'In behandeling'. When i approve his status to Goedgekeurd (approved) or disapprove to Afgekeurd the selection of this account must disappear from the reference selector drop down selection menu. I wanted to do this by entering a xpath constraint in the reference selector. So i whent to the properties of the reference selector itself and at the box xpath constraint i entered: [MyFirstModule.OrderKlant/MyFirstModule.Order/Gegevensstatus='In_behandeling'] I don't get any error messages when i type this. But when i run it, the selection menu of the reference selector always stays empty, no matter what the status of the enumeration is. I hope someone can help me with this problem Kind regards, Peter Schakel
