[TYPO3-english] Check with Typoscript if Templavoila "Link field" is set

Thanks for the long write up, Loek :)

After trying to wrap my head around the practicalities of your suggestions, I played a bit around with Templavoila, and ended up with something much simpler and maintainable (I think). In Templavoila I simply created an additional "Not mapped" field (field_readonlinelinkfield) - and made this of type "Link field".

In my TS I then just simply do this (with your override trick):

lib.readonlinelink = TEXT
lib.readonlinelink.value = {$readonlinelinktext.da}
lib.readonlinelink.typolink {
         parameter.data = getIndpEnv:TYPO3_REQUEST_URL
         parameter.override.field = field_readonlinelinkfield
         title = {$readonlinelinktext.da}
} 

And it works! Thank you so much for your efforts :)
