[TYPO3] RealURL: PostVars are either all mapped or none, how to change that?

[Andreas Förthner]

Hi,

I am configuring the RealURL Extension for my page. There I have some 
Parameters for my own extension. These parameters can be existant on any 
page, because the plugin could be everywhere. And it's also possible 
that there are just a few of these parameters. Just to make this clear: 
   I am linking to some records in the database those records could be 
associated to a subcategory or not, so the subcategory parameter is only 
  existant if the record is associated to one. Of course this shoul be 
the same in the URL.

What I did was the configuration of those parameters as fixedPostVars. 
This work so far very good, everything is mapped, but if there is one 
parameter missing the URL gets an //. Meaning if one of the parameters 
is there, all of the parameters defined are tried to get translated, if 
there is one missing in the original url I get an empty one, ending in a 
double slash.

I tried to do something like 'noMatch' => 'bypass' but that didn't work 
too, because then nothing got translated anymore.

How do I have to configure the Extension that a parameter gets 
translated if it's there and if it's not there it should just be ignored.

Did anyone of you achieve that behavior?

Thanks for any help!
