Build 6.0.29 (Probably applies to 5.4 also, but not tested)
Using Edit -> Stream Parameters... and then using the Browse button to find and load a valid XML file, displays the XML structure in the Match section of the dialog. Choosing the Path... button displays another dialog which shows the XML structure in the Path: section. Choosing any element in the path displays the correct "xa-input::" path expression and enables the Add Path button. However, selecting the Add Path button (for any expression, valid or not) results in an Error box with no message and a stack trace ending in a java.lang.NullPointerException.
There is no way to complete the instream elements to be added to the document, using the dialog; if you enter no path expression, an Information dialog is displayed (Please select a path or click on Cancel button.).
