Folks,
I need to have a dynamically populated displayPropertyKeys for a list page. I
was trying a couple things and eventually got the following tip. Unfortunately
it seems not to work
In Session.java
private NSArray<String> listElectronicDocumentDisplayPropertyKeys;
public void setListElectronicDocumentDisplayPropertyKeys(NSArray<String>
keyArray) {
listElectronicDocumentDisplayPropertyKeys = keyArray
}
public NSArray<String> listElectronicDocumentDisplayPropertyKeys() {
return listElectronicDocumentDisplayPropertyKeys;
}
With the following rule:
100 : pageConfiguration = 'ListElectronicDocument' => displayPropertyKeys =
session.listElectronicDocumentDisplayPropertyKeys
[com.webobjects.directtoweb.DelayedKeyValueAssignment]
All I get is a nice crash :-(

I can sort of understand what is going on: D2W thinks that
session.listElectronicDocumentDisplayPropertyKeys is a string instead of
evaluating it. But isn't the rule system supposed to recursively resolve this?
Any other idea? Or would I have to meddle with ER2DWListPage.java?
Thanks for any quick answer
