Typo3 tt_news add Parameter to URL - typo3

Question

how can i read out the current id from tt_news and add this as a parameter to the url
a small review of my TYPOSCRIPT
2 = TMENU
2 {
wrap = <ul class="naviMainLevel2"> | </ul>
NO {
wrapItemAndSub = <li> | </li>
}
ACT = 1
ACT {
wrapItemAndSub = <li class="active"> | </li>
#get current tt_news id add it to the menu
additionalParams.data = GP:tx_ttnews|tt_news
additionalParams.intval = 1
additionalParams.wrap = &tx_events_pi1[newsUid]=|
#returns only &tx_events_pi1[newsUid]=0
#maybe is it possible with RECORDS tt_news.mbl_newsevent, to get the id?
}
CUR = 1
CUR < .ACT
}
url should then look like this: www.example.com/news/news-tech?&tx_events_pi1[newsUid]=55
Updated:
i think this is a problem with the extension mbl_newsevent it shows only news with an registration option and a button with the current tt_news id...generated with this TS:
plugin.tt_news.mbl_newsevent {
registrationLink_typolink {
title.data = LLL:EXT:mbl_newsevent/locallang.xml:registerLinkLabel
parameter = {$powermail.plugin.pid}
parameter.override.field = tx_mblnewsevent_regurl
additionalParams.field = uid
additionalParams.intval = 1
additionalParams.wrap = &tx_powermail_pi1[eventUid]=|
#this returns the correct tt_news id for the button
}
}
i need the same way for my url....

Answer 1

If I understood correctly, you need to correct your code in a following way:
2 = TMENU
2 {
wrap = <ul class="naviMainLevel2"> | </ul>
NO {
wrapItemAndSub = <li> | </li>
}
ACT = 1
ACT {
wrapItemAndSub = <li class="active"> | </li>
#parameter.override.field = tt_news_id ||uid
# ^ you don't need this line, becasue you still need
# the current page id in url and it shouldn't be overriden
# by some other param
# next you need to get current tt_news uid from GET
# as you mentioned in your comment
additionalParams.data = GP:tx_ttnews|tt_news
additionalParams.intval = 1
additionalParams.wrap = &tx_events_pi1[newsUid]=|
}
CUR = 1
CUR < .ACT
}
