6.5.1 Model Binding Expressions and Computed Expressions

"Note:

If the index() function is being invoked from a model binding expression  
or computed expression, it will be necessary to invoke rebuild manually.  
If the repeat index change occurs due to an implicit behavior such as a  
change to the focused control, then the rebuild (along with recalculate,  
revalidate and refresh) can be invoked from a handler for DOMFocusIn  
attached to the repeat or each repeat object."

Presumably it is worth us pointing out here that using indexref instead of  
index() solves this problem.
