Subject [JXPath] Problem adding objects to an ArrayList Variable
Date Thu, 06 Feb 2003 11:52:23 GMT
Hi,

Attached is a small test program that simply defines a Context like this:

 Object o = new Object ();
 JXPathContext context = JXPathContext.newContext( o );
 context.getVariables().declareVariable("myList", new ArrayList() );

 FunctionLibrary library = new FunctionLibrary ();
 library.addFunctions( new ClassFunctions ( List.class, "list" ) );
 context.setFunctions( library );

The output from executing several XPath expressions on it is thus:

getValue("list:size($myList)") returns: 0

getValue("list:add($myList, 'hello')") returns: true

getValue("list:size($myList)") returns: 0

getValue("$myList") returns: []

I would expect the String 'hello' to be added to the list, and therefore the second call to
size should return 1.

Am I doing something wrong here?

Cheers,

Adam
