Forms calling Reports output issue RTF/PDF - strange issue

Question

Dear All,
I'm looking for a bit of help with a strange situation calling reports from Forms.
This problem I'm getting in both 11.1.1 and 11.1.2 of Forms/Reports. Client is WinXP/7 (issue appears on both), Weblogic server is Linux (SLES11 and Red Hat - issue on both)
So the issue is
1. calling a report with output as RTF (this works fine and we use OLE2 to open the report in Word)
2. Wihile in that form call the same report though change the output to be created as PDF in the cache and the report then opens in IE (this too works fine)
3. Now if we try and do number 1 again (still in the same form) and run the same report again and choose to generate as RTF and open in word, it erroneously generates the report in PDF format but with an .RTF extension on the file.
Of course most of the time people would not want to do this, but the client has identified this issue and classified it as a bug, so we need to fix it (and it doesn't happen in the Forms6i version it is migrated from).
I have tried to ensure that the parameter list is correctly deleted and re-created, which appears to be the case. I also tried to generate a new unique parameter list for every run, which made no difference to the problem.
If I choose to run a completely different report, the problem has reset itself. So the problem exists only when I've chosen the PDF output and then run the same report thereafter as RTF output to a file.
Code to prepare for the RTF option is:
Add_Parameter(pl_id,'destype',TEXT_PARAMETER,'FILE');
Add_Parameter(pl_id,'desname',TEXT_PARAMETER,l_temp_env||'/'|| p_report || '.rtf');
l_report_desname := l_temp_env||'/'|| p_report || '.rtf';
Add_Parameter(pl_id,'DESFORMAT',TEXT_PARAMETER,'RTF');
Add_Parameter(pl_id,'REPORT_DESFORMAT',TEXT_PARAMETER,'RTF');
Add_Parameter(pl_id,'mode',TEXT_PARAMETER,'BITMAP');
l_report := p_report;
Code used to prepare for PDF option is:
Add_Parameter(pl_id,'destype',TEXT_PARAMETER,'CACHE');
Add_Parameter(pl_id,'desname',TEXT_PARAMETER,'');
Add_Parameter(pl_id,'desformat',TEXT_PARAMETER,'PDF');
l_report := p_report;
Any ideas gratefully received.
cheers

Answer 1

So I delete the paramlist correctly, then the code is:
IF (p_display_method = 'W')
THEN
--WORD Format
     --delete file on client
     Delete_File('c:\temp'||'\'|| p_report || '.rtf');
     --delete file on app server
     host('rm '||l_temp_env||'/'|| p_report || '.rtf');
     Add_Parameter(pl_id,'REPORT_DESTYPE',TEXT_PARAMETER,'FILE');
     Add_Parameter(pl_id,'DESTYPE',TEXT_PARAMETER,'FILE');
     Add_Parameter(pl_id,'DESNAME',TEXT_PARAMETER,l_temp_env||'/'|| p_report || '.rtf');
     l_report_desname := l_temp_env||'/'|| p_report || '.rtf';
     Add_Parameter(pl_id,'DESFORMAT',TEXT_PARAMETER,'RTF');
     Add_Parameter(pl_id,'REPORT_DESFORMAT',TEXT_PARAMETER,'RTF');     
     Add_Parameter(pl_id,'MODE',TEXT_PARAMETER,'BITMAP');
     Add_Parameter(pl_id,'printjob',TEXT_PARAMETER,'no');
     l_report := p_report;
ELSIF (p_display_method = 'E')
THEN
--EXCEL format
     --delete file on client
     Delete_File('c:\temp'||'\'|| p_report || '.csv');
     Delete_File('c:\temp'||'\'|| p_report || '.xls');
     --delete file on app server
     host('rm '||l_temp_env||'/'|| p_report || '.csv');
     Delete_File(l_temp_env||'\'|| p_report || '.cvs');
     Delete_File(l_temp_env||'\'|| p_report || '.xls');
     Add_Parameter(pl_id,'destype',TEXT_PARAMETER,'FILE');
     Add_Parameter(pl_id,'desname',TEXT_PARAMETER,l_temp_env||'/'|| p_report || '.csv');
     Add_Parameter(pl_id,'desformat',TEXT_PARAMETER,'csv.prt');
     Add_Parameter(pl_id,'REPORT_DESFORMAT',TEXT_PARAMETER,'csv.prt');
     Add_Parameter(pl_id,'MODE',TEXT_PARAMETER,'character');
     Add_Parameter(pl_id,'printjob',TEXT_PARAMETER,'no');
     l_report := p_report || '_d';
ELSIF (p_display_method = 'P')
THEN
-- PDF Format
     Add_Parameter(pl_id,'destype',TEXT_PARAMETER,'CACHE');
     Add_Parameter(pl_id,'desname',TEXT_PARAMETER,l_temp_env||'/'|| p_report || '.pdf');
     Add_Parameter(pl_id,'DESFORMAT',TEXT_PARAMETER,'PDF');
     Add_Parameter(pl_id,'REPORT_DESFORMAT',TEXT_PARAMETER,'PDF');     
     l_report := p_report;
END IF;
So all of the above works fine when generating a report the first time you enter a form, but if you run a PDF output report then immediately in the same form generate the report again to a non-PDF format, it comes out in incorrectly in PDF format.
