Subject: Clear load ID when assigning to a component
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=08d3b5a55fad7439b47fc93d8ba604cbeb7e19ca

Clear load ID when assigning to a component

This prevents an issue where reading the value of the entire variable
afterwards would incorrectly use the old cached load.
