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; i<repeater.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.
