Hi people,
I have a question, which I couldn't answer by reading the docs.
What happens, if the XPath uses '../' at the beginning to go back one step?
Will the parentContext be used to evaluate the XPath?
Here's my testcode (adapted from the original test code):
public void testRootHandling(){
if (!enabled){
return;
}
System.out.println("testing root handling start");
JXPathContext context = JXPathContext.newContext(bean);
JXPathContext nestedContext = JXPathContext.newContext(context,
bean.getNestedBean());
testGetValue(nestedContext, "/boolean", Boolean.FALSE);
System.out.println("accessing /boolean in nested context worked!");
testGetValue(nestedContext, "../boolean", Boolean.FALSE);
System.out.println("accessing ../boolean in nested context
worked!");
}
The corresponding output:
test.jxpath:
[echo] Running JXPath tests ...
[java] .testing root handling start
[java] accessing /boolean in nested context worked!
[java] E.....

It looks like it's possible to go back using '/' at the beginning, but using
'../' doesn't work. Has anyone got some advice?
I'm using commons-jxpath-1.0
I'm new to JXPath, so excuse me, if I understood something wrong or if
there's an obvious solution.
Mit freundlichen Gruessen,
