It's not as easy as modifying the code the way I did, because if you use
the validation in a form, and the validation fails, it goes through the
tiles processor with and uri null, and because of the modifications it
fails coming back to the original screen.
So I've put the old code(in fact the normal code) and change the
include/forward code from:
...
if (doInclude) {
log.info("Tiles process complete; doInclude with " +
uri);
doInclude(sacontext, uri);
} else {
log.info("Tiles process complete; forward to " + uri);
doForward(sacontext, uri);
}
...
To
...
uri = uri.trim();
if (uri.length()>0)
{
if (doInclude) {
log.info("Tiles process complete; doInclude with " +
uri);
doInclude(sacontext, uri);
} else {
log.info("Tiles process complete; forward to " + uri);
doForward(sacontext, uri);
}
}
...
And put path = "" in the tiles-def.xml. Again I don't know the
implications, but at this moment it works for me.
