  9. Thanks but that is not what I really want. The onbeforeunload event will trigger in any of the following scenarios: user refreshes page, user types in another URL in the location field, users clicks...
  10. I kind of feel bad about making this post, but I figure if anyone knows how to do this, someone using Ext will know. So here goes.

    Internally the store keeps a reference to the data put in the store, but also a reference to a single "filtered" version of the data which is a...

    Hello,
