| <h1>XPath Expression Editor</h1> | |
| <p> | |
| 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 <strong>CTRL</strong> and | |
| <strong>SPACE</strong> 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: | |

| <h2>Note</h2> | |
| <p> | |
| 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. | |
