CForms: Updating all instances of a widget in a repeater
Hi there,
I've got a repeater with two selection lists in; staffmemeber and staffrole.
Upon a value being changed on the staffrole or another selection list outside
of the repeater (department) the list of staff members change. I'm using an
on-changed-value on the staffrole repeater and that works fine but I'd also
like to change the list if the department is updated for all the rows in the
repeater using javascript on the department's on-changed-value event.
I tried something like:
var staff_list = event.source.parent.lookupWidget(stafflist).getChildren();
var staff_item = null;
var staff_member = null;
var staff_role = null;
while(staff_list.hasNext())
{
staff_item = staff_list.next();
staff_member = staff_item.lookupWidget(staffmember);
staff_role = staff_item.lookupWidget(staffrole);
//set a new staff member event
}
but I got stuck at the first hurdle. That is that it looks like stafflist
doesn't actually have any children (hasNext() returns false). It certainly
should have. If it does have children is it then possible to do the latter
logic of getting each child and looking up the components I want to get the
value of and change the values of?
Is there a different or better way that I should do this?
Thanks,
Gary

I think to get the rows from a Repeater you have to use getRow() rather
than getChildren(). I think I've used something like this in the past:
var repeater = ...
for(var i=0; irepeater.getSize(); i++) {
var row = repeater.getRow(i);
...
}
Hope that works
Actually the Javadoc for Repeater doesn't even look like it has a
getChildren() method, so I'm not sure why you weren't getting an error.
It seems odd that Repeater doesn't implement ContainerWidget; even its
Javadoc says it should. Interesting.

You are quite right; it isn't part of the class. I'll double check the code is
actually being called :D. Thanks for pointing me to the correct documentation.
For some reason I was looking at the container class.
Thanks again,
Gary
