There is a logical bug:
Try to add a:
*IncludeViewResource model again: ${it}* at the end of the include.jsp. The
it is not the expected one. I would expect the one of IncludeViewResource
but as we've included the TwoResource class, the it has been overwritten by
it's model witch is the string 'TwoResource'
I can't think how could c:import work out of the box without named model.
I'll try to play with a jsp tag that will replace the model in each include.
That should work (I hope :-) ).
