load of js libs on login page

Hi,

We do have a power edition purchased and i am trying to use the Network Performance module in order to begin loading(caching) the smartgwt libraries on login page.

This is what I have on my login.jsp:
<isomorphic:loadISC cacheOnly="true" modulesDir="modules/" skin="Enterprise"/>

And on accessing the login page it loads the required libraries with the corresponding version, e.g.: ISC_Core.js?isc_version=v8.3_2012-11-20.js

On the main html of the application however the .nocache.js file loads the libraries again, this time without the version.

Specifying the libraries separately like this:
<script src="xcrf/sc/modules/ISC_Core.js?isc_version=v8.3_2012-11-20.js"></script>

does not really help since the .nocache.js tries to load them again without the version.

Am I missing something, is there some sort of magical setting that I am missing?

Thanks
Stefan
