Let me describe the scenario:
(Have you looked at http://bugs.typo3.org/view.php?id=4176 ?)

Problem:
---------

You want to set a TS-value in the <typoScript>-Section based on a FCE
wich a user has inserted into the FCE via Backend Form. (i.e. 
color-properties for an
GifBuilder Object)

Normally you can use:
   "parameter.field = <some_fce_field_value>" inside <typoscript/> Tag

!!!BUT: This works only if parameter has stdWrap Properties... wich is not 
the case
for a lot of parameters. !!! So what to do now?. It's not possible out of 
the box.


So my solution solves this problem this way:
--------------------------------------------

Why not use the well known, already existing TV Constant Substitution,
wich would work for all kinds of TS-Parameters:

   "parameter = {$<some_fce_field_value>}"

The only thing that have to be added to TemplaVoila is a way
to access the current FCE field values with

<TypoScript_constants>
<[constant_name]>
value_from_fce_field
</[constant_name]>
</TypoScript_constants>

so that the values can be substituted into the typoscript code.

I hope it's clearer now.

Martin
