Hello -
In my quest to solve my many-to-many problem...
On my form I have a repeating list with two columns that is
dynamically generated.
Column a is name and column b has a popup of which I am trying to get
the selection.
What do I do to loop through the list to get the selected values upon
submittal?
Instead of binding the selection binding of the popup to an ivar, bind
it to a setter and getter method that do what you need to do.
For instance if the popup is going to allow you to reassign a
relationship: The getter should return the current relationship, the
setter should delete the existing one and create the new one.
So if you have a repetition of Users, with the popup showing companies.
User <<----> Company
Popup bindings:
list NSArray containing all companies
item userItem
selection selectedCompany
public Company selectedCompany() {
return userItem.company();
}
public void setSelectedCompany(Company value) {
if (userItem.company() != null) {
userItem.removeObjectFromBothSidesOfRelationshipWithKey(userItem.compan
y(), "company");
}
userItem.addObjectToBothSidesOfRelationshipWithKey(value, "company");
}
Y'know...
I just realized that this example is stupid...
You'd just bind userItem.company to the selection binding of the popup
and be done with it.
But the methodology is useful elsewhere I guess.
