has anyone seen this issue with the paging repeater widget?

Hi there,

I have a repeater widget with the "size" set to 10 rows.

All works well with say 15 rows shown on two pages, 10 rows on the first
and 5 on the second.

However, if I have 11 rows, 10 on the first page and 1 on the second,
then if I edit the 11th row (first row on page 2) to not satisfy my
query i.e. there are now only 10 rows that apply, on refreshing the
page i get the following error.

Has anyone seen this before and would there be a patch for it? or
should I file this as a bug.

thx
Paul

I solved it by changing the getCustomPageWidgetValue function in
EnhancedRepeater.java to the following, but can't say its the best solution.

public int getCustomPageWidgetValue() {
if (this.customPageField.getValue() == null) {
return 0;
}
else {
return ((Integer)this.customPageField.getValue()).intValue();
}
}
