UNCAUGHT_EXCEPTION CX_SXML_STATE_ERROR

Question

Hi All
I'm getting the following error when running my print form and see that the error is generated in the following macro xml_open_tag i_folder_name. The function module in which this happens is FPCOMP_FOLDER_BEGIN and I'm not sure how to deal with this error. When I 'Generate Preview Data' in SFP->LAYOUT->EDIT->Defaults, the XML is tip-top, but calling the form from my print program generates this error. Any suggestions? Thank you.

What happened?
    The exception 'CX_SXML_STATE_ERROR' was raised, but it was not caught anywhere
     along
    the call hierarchy.
    Since exceptions represent error situations and this error was not
    adequately responded to, the running ABAP program
     'CL_SXML_WRITER================CP' has to be
    terminated.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SXML_STATE_ERROR', was not caught
     in
    procedure "FPCOMP_FOLDER_BEGIN" "(FUNCTION)", nor was it propagated by a
     RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    Method 'IF_SXML_WRITER~OPEN_ELEMENT' cannot be called at this position in the
    XML stream

Hello,
if your form is working without the data and not with it, there is something malformed somewhere within:)) I can recommend you to experiment with your form context - one after another disable your context elements and find out which one causes the error.
I have experienced such problems when using certain DDIC types which were not processed correctly. I have never found the "right" solution, but I have found that if I replace the "bad" type with some other one which can hold the same information, it works and it is quick. That is what mattered the most for me.
Hope this helps a bit, Otto
