If I retrieve the customField-Keys from the webservice and pass them to the getWorkItemByUriWithFields-Method, I get an Exception:
com.polarion.alm.ws.WebserviceException: Client passed undefined keys
Which does not fit the Documentation which states:
Gets the names of defined custom fields.
Does anyone know, if it is possible to retrieve only the defined keys?
I could load the whole workitem, but it defies the idea of making my queries smaller by letting the user choose the fields he wants...
