A blank row is getting created under the last categorized column

I have created a discussion forum. In the view, I created the indentation for response documents. The view has three fields named ‘Date’(Categorized with twistie), Untitled(Categorized with twistie and show responses only option checked)(for indenting the response document with width as 1) and ‘Topic’(Categorized with twistie). The fields Untitled and ‘Topic’ are set to show the same ‘Comments’ field from the Document and Response to response forms.

The problem I am facing is a new blank row is getting created under the last categorized column in the view each time I am creating a new document. But this is not happening while I am creating a response.

What’s up?

N.B. My ‘Create new topic’ action formula is …

@Command([FileSave]);@SetTargetFrame(“DisBottom”);@Command([OpenPage];“ForumPage”)

and ‘Respond’ action formula is …

@Command([ComposeWithReference];“”;“Forum12”;“3+4+8”).

Looking forward. Thank you very much.
