It sounds to me like you're submitting the row object rather than the ID of the
object for which you want to operation upon.
The following example should work:
<display:table name="notifications" uid="tableListUid">
<display:column>
<s:form action="acknowledgeDocumentNotification">
<s:hidden name="documentId" value="%{#tableListUid.documentId}"/>
<s:submit key="button.submit"/>
</s:form>
</display:column>
</display:table>
The above code gets the document id from the uid specified and uses it as a
hidden value in the form submission. There are other neat way to avoid having a
form per row, but this is simple enough.
Your acknowledgeDocumentNotification action should then only receive the
documentId parameter with the row's document id as the only input value.
Thanks,
Chris

hi,
not sure if i understand what the problem is. You get all items of a list
posted when you submit your form? How does the html look like? What form
elements are generated by display?

Christoph
