Hi Ted,
I don't do DisplayGroups, but I think the problem is that since
"selectedObject" could be any type, there is no way for the component
validator to know that password is valid.
I know with non-inline components, you simply add "//valid" after the
binding in the .wo file. I'm not sure how that is done with inline tags.
Last I can find (from Mike back in May 2008), it is supposed to work
like this: <wo:WOTextField value = "$userDG.selectedObject.password //
valid" size = "35" />

I have started an project to track contacts... It is a very simple
concept but I thought I would use it to learn something of
displayGroups.
Here is how I am using them now:
in my .java I create a definition with:
public ERXDisplayGroup<User> userDG;
and in the constructor:
userListEO = ERXEC.newEditingContext();
userList = User.fetchByLastName(userListEO);
userDG = new ERXDisplayGroup<User>();
userDG.setObjectArray(userList);
In my HTML I am doing this:
<wo:WOTextField value = "$userDG.selectedObject.password" size =
"35" />
I get an error: there is no key 'password' for keypath
'userDG.selectedObject' in AdminMain
userDG is of type User and User does indeed have a 'password'.
I notice there is a tab in Eclipse that says DisplayGroups but I am
doing nothing here.
The app runs just fine and does what I expect. Why do I get this
error?
BTW, I am using this same technique in a different component and I
get no error.
Ted
