[TYPO3] real url doesn't substitute a variable ([ for %5B problem?)

[Rens Admiraal]

Hi all,

I start this new thread because my previous post was not describing  
enough, and when I take another look I see the problem is also not  
what I thought (Dmitry, thanks for your reminder!).

I thought I had a problem with my plugin, but that wasn't true, it  
turned out to be a configuration problem in Real_url and, it is  
solved. But, now I encounter the next problem.

I have made a menu using the user_menuFunc  class posted by Peter  
Klein on typo3wizard (http://www.typo3wizard.com/en/snippets/menus/ 
create-menus-using-data-from-other-tables-than-pages.html).

With additionalParams.wrap I add a variable to the URL with brackets  
in it. I want this to be substituted by real url (it should show the  
groupname). Unfortunately this doesn't work, and it gives urls like:
http://www.kunstboekwinkel.nl/nc/webshop/?tx_AmbitionWebshopFE_pi1% 
5Bpgroup%5D=6

What am I doing wrong?

TypoScript for menu:
page.includeLibs.usermenu = fileadmin/menuFunc.php

shop.mainmenu = HMENU
shop.mainmenu.special = userfunction
shop.mainmenu.special.userFunc = user_menuFunc->makeMenuArray
shop.mainmenu.special.userFunc.table = tx_AmbitionWebshopBE_groups
shop.mainmenu.special.userFunc.select.fields = pgroup AS pid, uid, title
shop.mainmenu.special.userFunc.select.where = pgroup=0
shop.mainmenu.special.userFunc.select.orderBy = sorting ASC
shop.mainmenu.1 = TMENU
shop.mainmenu.1 {
	wrap = <ul>|</ul>
	NO {
		doNotLinkIt = 0
		stdWrap.field = title
		stdWrap.typolink.parameter = 29
		stdWrap.typolink.additionalParams.field = uid
		stdWrap.typolink.additionalParams.wrap= &tx_AmbitionWebshopFE_pi1 
[pgroup]=|
		allWrap = <li>|</li>
	}
}
