Exception while retrieving data for a widget

[Fisoes]

Hi,

I have a listview (mx 8.7.0) with an association via xpath.
When i opening the page i get the following error:

Caused by: com.mendix.systemwideinterfaces.MendixRuntimeException: Input '//Employee.Employee[Employee.Employee_Customer='7318349394477763']JanHenkPiet' could not be parsed
Error on line 1 character 66: extraneous input 'JanHenkPiet' expecting

I got 3 employees called Jan, Piet and Henk. any idea why this is not working?

When i had the listview by association i didnt even see any error or search field. So i switched to xpath but than i got this error.
