com.businessobjects.rebean.wi.DocumentInstanceImpl.setPrompts error

[Former Member]

I have code works in old version, as:

ReportEngine reportEngine = getReportEngine(session,  reportEngines);

DocumentInstance reDocInst = (DocumentInstance) reportEngine.openDocument(webiDoc.getID());

Prompts prompts = reDocInst.getPrompts();

for (int j = 0; j < prompts.getCount(); j++) {

                            Prompt prompt = prompts.getItem(j);

                            String promptName = prompt.getName();

                            String bindName = (String) promptMap.get(promptName);                           

                            String promptval = request.getParameter(bindName);

                            System.out.println("name="+promptName+  " value="+promptval + " Bind Name="+bindName);

                            String[] vals = null;

                            if (promptval.equals("CurrentMonth")) {

                                vals = new String[2];

                                vals[0] = "CurrentMTD";

                                vals[1] = "CurrentFut";

                                prompt.enterValues(vals);

                                PromptsUtil.populateWebiPrompts(prompts, webiDoc);

...

}

Since the  PromptsUtil.populateWebiPrompts can't used anymore, I code as:

ReportEngine reportEngine = getReportEngine(session,  reportEngines);

DocumentInstance reDocInst = (DocumentInstance) reportEngine.openDocument(webiDoc.getID());

Prompts prompts = reDocInst.getPrompts();

for (int j = 0; j < prompts.getCount(); j++) {

                            Prompt prompt = prompts.getItem(j);

                            String promptName = prompt.getName();

                            String bindName = (String) promptMap.get(promptName);                           

                            String promptval = request.getParameter(bindName);

                            System.out.println("name="+promptName+  " value="+promptval + " Bind Name="+bindName);

                            String[] vals = null;

                            if (promptval.equals("CurrentMonth")) {

                                vals = new String[2];

                                vals[0] = "CurrentMTD";

                                vals[1] = "CurrentFut";

                                prompt.enterValues(vals);

                                reDocInst.setPrompts();

                                reDocInst.save();

                         }

...

}

When I execute the code, I have:

If I removed the reDocInst.setPrompts();

then, I can execute the program, and remove me a report with no data.

I want to know where the problem cause this.  And, it is really difficult to find document about this kind issue of BO upgrade.

I really appreciate your help.

Thanks.

Or, I moved the

                                reDocInst.setPrompts();

                                reDocInst.save();

out of for loop, the report can generate, but, no data.
