Hi loeppky,

you can see your BrowseButton in action here: http://filetree.extjs.eu

I found some issues, don't know yet if it's because of my misconfiguration or bugs:

  1. BrowseButton doesn't open file dialog in Opera neither Winblow$ nor Linux version
  2. When it is in bbar (menu button at the top-left corner) it doesn't seem to work reliably in IE7 after adding several files - even after I've removed doctype
  3. Works perfect in Firefox

Issues 1 and 2 are of no importance for me as I force my users to use Firefox but they can matter for others.

You can download zip here.
