I am using the Diana EAP #9805. In the Flex editors the completion seems to be broken for functions that are declared with the AS3 visbility (Namespace: http://adobe.com/AS3/2006/builtin). E.g. for Strings the only available completion is length, which is the only publich function that is not declared with the AS3 visibility. However functions like lastIndexOf or substring should also be listed in the completion.
Is this a known defect in #9805?
