Hi,
I am new to WO and I am trying to create a new "Display Group
Component" or "Display Group Application". It is created okay and
it displays correctly in Safari, I can select the items that are
listed in the repeat field, but if I edit any of the items it
always changes the first item in the repeat list. Any help would
be appreciated.
WOD listing
SelectionList: WORepetition {item = user; list =
userDisplayGroup.displayedObjects; };
SelectObjectLink: WOHyperlink {action = selectObject; };
ObjectIdentifier: WOString {value = user.username; };
ModificationForm: WOForm {multipleSubmit = true; };
usernameField: WOTextField {value =
userDisplayGroup.selectedObject.username; };
firstnameField: WOTextField {value =
userDisplayGroup.selectedObject.firstname; };
lastnameField: WOTextField {value =
userDisplayGroup.selectedObject.lastname; };
You are trying to edit in the repetition?
Not editing in the repetition, selecting the hyperlink in the
repetition.
I am using the default behavior that creating a new "Display Group
Component" gives you by using an EOModel containing username,
firstname, lastname.
Shouldn't those the user.username etc instead of
userDisplayGroup.selectedObject.username?
I tried that and the selection from the repetition never fills out
the selection fields for editing.
