I've tried to modify the execute method of TilesPreProcessor from
...
if(uri == null)
{
log.debug("no uri computed, so pass to next command");
return false;
}
if(controller != null)
{
log.trace("Execute controller: " + controller);
controller.execute(tileContext, sacontext.getRequest(),
sacontext.getResponse(), sacontext.getContext());
}
...
To
...
if (controller != null) {
log.trace("Execute controller: " + controller);
controller.execute(tileContext,sacontext.getRequest(),sacontext.getRespo
nse(),sacontext.getContext());
}
if (uri == null) {
log.debug("no uri computed, so pass to next command");
sacontext.setForwardConfig( null );
return false;
}
...
So it execute the controller even if the uri is null, and after that if
the uri is null, it will put the ForwardConfig to null and return,
because is the end of the processing. It works for me, but I don't know
all the implications of this change.
