checking a empty list

Hi group!

I wonder if it's possible with a logic tag, to check if a List in a form is
empty.

This doesn't work, it just checks if the attachmentsList is null:
<logic:present name="document" property="attachmentsList">

Regards, 
Bernhard

Try this:

<bean:size id="size" name="document" property="attachmentsList"/>
<logic:equal name="size" value="0">
...
</logic:equal>

Best regads
