The Process Developer Disable Selection Failure extension allows an XPath query in the From clause of an assignment Copy operation to return an empty node set. If it does, the target node for the assignment is deleted. You can use this extension on a process-by-process basis or set a preference to include it in all processes. When you use the extension, an extension namespace and process attribute are added to the process as follows:
<bpel:extension mustUnderstand="yes" namespace=
The process extension is enabled during simulation in Process Developer and enabled for execution on the Process Server.
To enable or disable this extension for an individual process:
In the process' Properties view, select the All tab.
In the Disable Selection Failure row, select Yes or No from the pick arrow.
The extension is added to the Outline view, and its elements and attributes are added to the BPEL source code.
