The target attribute for WebLinks

Hey dudes,
im trying to open a WebLink with target=2 (the language reference tells me its “kTargetNewWindow (2) New window”) but this never works/worked for me.
I tried many possibilities but without a solution.
The language reference for the WebLink itself tells me “You can use the Target property to have the URL open in another browser window or tab.”
like i said before, it doesn’t work.
Is it just me or doesn’t it work?
Not even a Popblocker shows up, the link just loads on my current Webapp.
FYI: I try to visit the WebLink URL from a button
Anyone out there who is able to help me?:

Thanks in advance ~

nevermind… my problem is somewhere else.
