Odd. I know I've used instance methods in JXPath before. But I can't
say I tried to do so where the instance method was on a member item of
a collection.
One thing I can say is that I've had difficulties in the past with the
1.2 release where my object graphs contain a mixture of maps,
collections, and pojos.
Suggestion - try your test case with one of the JXPath nightly builds.
I had to do that because some fixes for traversing collections of
collections which contain maps, etc. The 1.2 release is quite old.

Hello,
Thanks for the tip - I tried that but unfortunatly it does not work, I
still get the same problem. The stack trace is now:
---
org.apache.commons.jxpath.JXPathException: Invalid XPath:
'.[1]/getQuestion(.[1], \'lastname\')'. Syntax error after: '.[1]/g'
org.apache.commons.jxpath.ri.Parser.parseExpression(Parser.java:60)
org.apache.commons.jxpath.ri.JXPathContextReferenceImpl.compileExpression(JXPathContextReferenceImpl.java:218)
org.apache.commons.jxpath.ri.JXPathContextReferenceImpl.getValue(JXPathContextReferenceImpl.java:247)

It is the same problem. Interestingly I did try putting a list into the
JXContext and calling size as follows:
List objValues = new ArrayList<String>();
objValues.add("test1");
objValues.add("test2");
JXPathContext objContext = JXPathContext.newContext(objValues);
System.out.println(objContext.getValue("size(.)"));
assertEquals("test1", objContext.getValue(".[1]"));
This works, it prints out 2 for the size of the list. I wonder if it is
because the method I am calling has parameters? In the meantime, I'm gonna
trawl trhough the testcases in the source to see if I can find an example.
Thanks for your assistance.
Cheers,
Neil
