[pLog-svn] {dynamic} tags and plugins

[Ahmad Saleh]

Hi
I think the problem here is not in {dynamic} or in {include}, I think the
plugin object doesn't reach to the template because it's cached so if you
can assign plugin object to smarty before you check if the page is cached it
will work.

regards,
    Ahmad
