Problem invoking weblog/mod.weblog twice in one plugin

For a plugin I’m working on, the weblog module needs to be run twice. But when I run it the second time, it ignores any value in the entry_id parameter. I’m setting that parameter using

$TMPL->tagparams['entry_id']

syntax. Is there perhaps another way to set it?

Update: As often happens, as soon as I post here, I find the solution that had stumped me up to then. Before the second second invocation:

$TMPL->tagparams="";

Rather simple…
