[jira] [Updated] (JXPATH-177) Pipe in combination with variables
causes NullPointerException
[ https://issues.apache.org/jira/browse/JXPATH-177?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Martin Xarx updated JXPATH-177:
-------------------------------
Description:
xpath: name", result: ROOT name
xpath: /x/name", result: X name
xpath: $__root/x/name", result: X name
xpath: $__root/x/name|name, causes:

I'm using model created from java containers (Lists, Maps):
{
"name" : "ROOT name",
"x" : {
"name" : "X name"
}
}
The context is set to the root node. I'm using the following code:
JXPathContext xpathContext = JXPathContext.newContext(root);
Pointer p = contextContext.getPointer(xpath);
return p.getNode();
was:
xpath: name", result: ROOT name
xpath: /x/name", result: X name
xpath: $__root/x/name", result: X name
xpath: $__root/x/name|name
