I have a dialog where I have an image to upload/choose from repo.

The controlType is dam.

All works fine, except when a user ticks a radio button but do not actually 
upload a file NOR choose an image from the repo (internal link). In that case, 
I get a freemarker exception when calling [code]stkfn.getAsset(item, 
"image")[/code].

An obvious solution would be to check that the user actually uploaded an image 
OR chose an image from the repo. And insert this check before calling the 
method (mentioned above).

I have been looking around and tried a few things (see links below) but can't 
get this sorted. Any help is welcome, thanks in advance.
