multiple boolean checks in databinding

[springframework]

i need to code something that does this

enabled="{!Boolean(list.selectedIndex == -1 && list2.selectedIndex == -1)}"


i need the button only enabled when both lists have a selection.

my code gives an error though:
The entity name must immediately follow the '&' in the entity reference.

i searched on Yahoo and found the answer


either do:

Boolean(list.selectedIndex >= 0) && Boolean(list2.selectedIndex >= 0)

or switch your && statements to similar || statements

Also the "<" character isn't allowed

"<" checks must be converted to similar ">=" checks

Yeah, since it's XML, you have to encode certain entities to make it valid.
