Adrien,
Your example is so complex, I would advise extracting the simplest example
of the problem you face and sharing that. You may even solve your problem
in the process. It is a lot to ask volunteers more than you have to.
Tiddlywiki documents its own mechanisiums well. If you can find it in the
tiddlywiki.com documentation try looking inside tiddletwiki itself. For
example the title is displayed on tiddlers with
$:/core/ui/ViewTemplate/title and this will show the icon if it is
provided. Looking inside this tiddler we see it access the icon as follows
<$set name="foregroundColor" value={{!!color}}>
>>
<$transclude tiddler={{!!icon}}/>
Will this work for your problem?
Otherwise please restate the issue with a minimal case if at all possible.
Regards
Tony
