> The following ui:repeat tag with those values of size and offset throw a FacesException
with the message: "iteration offset cannot be greater than collection size."
> <ui:repeat var="listing" value="#{myListings.listings}" size="19" offset="20">
> It appears that the method _validateAttributes() in the UIRepeat class performs the validation
incorrectly.  It seems to assume that the value of size is the size of the collection, rather
than the desired iteration size.  Here is the relevant code from _validateAttributes():
>         if ((size > -1) && (begin > size)) {
>             throw new FacesException ("iteration offset cannot be greater " +
>                 "than collection size");
>         }
> The exception is thrown in the above case because begin > size, where begin = offset
= 20.
