[TYPO3-english] Getting the UID of a FCE with Typoscript

[Morten Kjems]

Hi

I am setting up a flexible content element that displays a small gallery 
with four images. I am using shadowbox to generate a lightbox effect 
when an image is clicked.

I have defined a field that identifies that the images belong to the 
same gallery.

ATagParams = rel="shadowbox[{field:field_galleryname}]"

But I would rather have the gallery identified by the UID of the FCE. 
This way the gallery and shadowbox effect will work even if the user has 
not entered anything in the galleryname field.

Now how do I do that?

I have tried:

ATagParams = rel="shadowbox[{field:field_uid}]"

But it dos not work

Any suggestions?
