hi everyone,

I use jxpath to manage an ArrayList of bean, the
Context is created like: JXPathContext
context=JXPathContext.newContext(list);

When I want to delete some objects in the arraylist,
i used  context.removeall, but it doesn't work.
Before and after call of removeall, the value of
count is always 1.

context.getVariables().declareVariable("heure", _h);

System.out.println(context.getValue("count(/.[heureSelected=$heure])"));
 ====> 1.0
context.removePath("/.[heureSelected=$heure]");

System.out.println(context.getValue("count(/.[heureSelected=$heure])"));
====> 1.0

I tried too iterator.remove(), i got a exception.

Iterator<HeurePrescription> iter =
context.iterate("/.[heureSelected=$heure]");
 while(iter.hasNext()){
     iter.next();
     iter.remove();
 }

Any help is appreciated.

Thanks in advance

Are you using the JXPath 1.2 release?  There are
innumerable bugfixes in svn trunk.
