XPath Expression Editor

The XPath expression editor provides context-sensitive assistance in the form of pop-up proposals. The light bulb icon indicates that content assist is available by pressing the CTRL and SPACE keys simultaneously. The editor will display appropriate help information based on what it knows about variables currently in-scope for the selected activity. An example is seen in the figure below:

Note

The BPEL 2.0 specification provides for the definition of an XPath language version at the process level, as well as the activity level (for those activities that make use of XPath). However, only XPath 1.0 is supported by the BPEL Designer and the JBoss Riftsaw runtime engine at this time.
