[TYPO3] addQueryString = 1 produces doubled id

[Krystian Szymukowicz]

hi

I am trying to create link to language switch:

I set:
config.uniqueLinkVars = 1


10 = TEXT
10.value = English
10.typolink.parameter.data = TSFE:id
10.typolink.addQueryString = 1
10.typolink.additionalParams = &L=2


and I get:
http://[host]/index.php?id=288&L=2&id=288&tx_ttnews[tt_news]=74&tx_ttnews[backPid]=288&cHash=222b2f0ffb

so as you can see id=288 is doubled.

Seems like config.uniqueLinkVars = 1 works because
there is no doubled L, but it fails to get rid of the second id.

Have you any idea how to get rid of the doubled id?

thanks for any hint
