You should never have put it in there, so definitely remove it. If you need to
set the reloadable attribute
I changed the package name. (by only removed the compay name), as I am not

Sorry about that.

Right there is a problem: the path attribute should be "", not &quo
And yes, both have the call.
I double checked, both trace log are exact the same.

How did you deploy you app as ROOT? It sounds like your app is deploying twice.
