How to specify more than 1 condition with && for a property in Flex

Question

I need to specify more than one condition for visibilty

visible="{data.allow && data.open}"

However, this gives the error "The entity name must immediately follow the '&' in the entity reference."

I could use a function, but I'd like to know if it is possible to do this directly with different syntax.

Answer 1

Because & is a special character in XML, you have to encode the & as &, so your expression would become visible="{data.allow && data.open}".
