Issue 197: Un-initializing BPEL variables

Status: received
Date added: 12 Mar 2005
Categories: Data Handling
Date submitted: 11 March 2004
Submitter: Yaron Y. Goland
Description: Is it legal/possible to un-initialize a variable in BPEL? What happens, for example, if one tries to assign a static from value that is empty? Should we allow for from-spec to be empty and have that mean that the target is uninitialized?
Submitter’s proposal: Being able to un-initialize variables is a generically useful thing. It makes it clear when a variable doesn't contain a 'useful' value. So I think we should provide a way to un-initialize variables.
Changes: 12 Mar 2005 - new issue
