As the title suggests, is there any documentation on the FlexBuilder “expressions” tab, and what expressions it can accept?

As far as I can tell, it can show the value of variables, but that’s it: comparisons, function and method calls all fail:

Edit: this is specific to FB3 — Flex Builder. Apparently FB4 — Flash Builder — is slightly less incompetent.

    It depends if you’re using FlexBuilder 3 or FlashBuilder 4. FB 3 has pitiful expressions capability. You can basically access variables and their member properties, period. And not always all the member properties.

    FB 4 gives you the ability to evaluate real expressions, like

    getStyle("vertical-align")
getStyle("vertical-align") + "foo" 
parseInt(getStyle("padding-left"))

    etc.
