Hi Theodore,
The following exchange from the WOLips list answers your question, I
think. If you use the component editor to add your WODisplayGroup, it
is named displayGroup1 by default which I then rename to
"objectDisplayGroup" as XCode used to do. You may want to follow the
convention, or rename the filter so that whatever you name your
display group is filtered out.

I have discovered that all of my page components that were created
with the DisplayGroupComponent wizard in Xcode are broken. The key
path convention that is used by the wizard throws errors in
component editor.
For example, the wizard inserts a button that inserts an entity
(entityDisplayGroup.insert(), which then becomes the display
group's selected entity) and then wires the selected entity to the
editing form fields by using a key path for the value such as
"entityDisplayGroup.selectedEntity.name". This key path is not
recognized. Is this a bug? Or was Xcode doing something
inadvisable and I should be changing all these pages to create
variables when an item in the display group is selected? The issue
seems related to my previous message in this thread.
It is just a validation "error".
It can't validate it as it does not know the type of object
returned by selectedObject. Go to the WOLips binding validation
rules preferences and tell it to not validate key paths with
displayGroup.selectedObject in them
If anyone else wants to add these to their rules I used:
.*.DisplayGroup\.selectedObject\..*
.*.DisplayGroup\.masterObject\..*

I have started using displayGroups for some of my table data... I
have a weirdness that is just getting by me.
I have defined a group:
public ERXDisplayGroup<Contact> dg;
and I can access it in my WO. I made some change (i don't really
remember what because I was finished with the section dealing with
the displayGroup) and suddenly I am getting these errors in my WO.
<wo:WOString value = "$dg.selectedObject.companyName"/>
There is no key 'companyName' for the keypath 'dg.selectedObject'
in UserMain..
It was fine a yesterday... and the displayGroup is defined and
created with
dg = new ERXDisplayGroup<Contact>();
dg.setObjectArray(contactList);
does someone have a clue where I need to look? BTW, my app runs
fine. I just have this error (red X) that I would like to get rid of.
