DCT calling another DCT

System

Has anyone had sucess with a DCT calling another DCT - right now I have a DCT which does a cgi-callout and in the cgi is a redirect to another DCT - problem is:
1) when I close the second DCT I get an error 'a runtime error has occurred do you wish to debug Error: cannot assign to '0 3_x'
2) The second DCT has a browse button and I click it I get a "Method not found" error

I have a case open with support on this - but I thought maybe
someone new of a workaround

Thanks
