[SOLVED] DomHelper Listener for Failure Error

[GordS]

I do not know if this possible as my research has turned up nothing. Here is my HTML code.

                var MergeDocument = function(){
                    PMID = currentRecord.data.PMID;
                    PEID = Ext.getCmp('DOCUMENT').getValue()
                    Ext.DomHelper.append(document.body, {
                        tag: 'iframe',
                        frameBorder: 0,
                        width: 0,
                        height: 0,
                        css: 'display:none;visibility:hidden;height:1px;',
                        src: 'vvcall.pgm?sid=' + sid + '&opt=' + opt + '&pgm=prmergesb&action=mergeDocument&PMID=' + PMID + '&PEID=' + PEID
                    });
                    Ext.getCmp('mergeWindow').hide();
                    parent.showMessage('', '<b><center>Your document will be available shortly<\/b><\/center>');
                };

Here is my RPG code.

         // If document created successfully
         // Then send the file to the browser
         // Else send error to the browser

         If Type = 'S';
           vvOut.download='Y';
           vvOut.file = %Char(Name) + '.docx';
           vvOut.contentType = 'application/x-download';
           vvout.binary='Y';
           vvOut_file(NewDoc:vvOut);
         Else;
           vvOut_toJsonPair('SUCCESS:0,MSG:' + %TrimR(Message));
         EndIf;

If my document creation fails how can I pick up the error message so it displays a proper message to the end user.

Thanks in advance

You could break the process into 2 steps. First use an ajax request to submit your request and params to merge the document and return 'success'. Check success returned - if the document merge fails then display a message, if 'success', then use the Ext.DomHelper code above to download the document.

Thanks for the help. Based on your response here is what my client side code looks like.

                function MergeDocument(){
                    Ext.Ajax.request({
                        url: 'vvcall.pgm',
                        params: {
                            action: 'mergeDoc',
                            pgm: 'PRMERGESB',
                            PMID: currentRecord.data.PMID,
                            PEID: Ext.getCmp('DOCUMENT').getValue()
                        },
                        success: function(response){
                            var check = response.responseText;
                            if (check) {
                                var data = Ext.util.JSON.decode(response.responseText);
                                if (data.SUCCESS == '1') {
                                    Ext.getCmp('mergeWindow').hide();
                                    parent.showMessage('', '<b><center>Your document will be available shortly<\/b><\/center>');
                                    Ext.DomHelper.append(document.body, {
                                        tag: 'iframe',
                                        frameBorder: 0,
                                        width: 0,
                                        height: 0,
                                        css: 'display:none;visibility:hidden;height:1px;',
                                        src: 'vvcall.pgm?sid=' + sid + '&opt=' + opt + '&pgm=prmergesb&action=downloadDoc&PATH=' + data.PATH + '&FILE=' + data.FILE
                                    });
                                }
                                else {
                                    Ext.getCmp(data.FLD).markInvalid(data.MSG);
                                    Ext.getCmp(data.FLD).focus();
                                }
                            }
                        },
                        failure: function(){
                            Ext.getBody().unmask();
                            Ext.Msg.alert('Failure', 'Failed to receive a response from server');
                        }
                    });
                };

Here is my RPG code for the merge part.

         // If document created successfully
         // Then send the file information to the browser
         // Else send error to the browser

         If Type = 'S';
           vvOut_toJsonPair('SUCCESS:1,FILE:' + %Char(Name) + '.docx,PATH:' +
             NewDoc);
         Else;
           vvOut_toJsonPair('SUCCESS:0,MSG:' + %TrimR(Message) +
             ',FLD:DOCUMENT');
         EndIf;

Here is my RPG code for the download part.

     **--------------------------------------------
     p DownloadDoc     b
     d DownloadDOc     pi

     D File            s            100a   varying
     D Path            s           5000a   varying
      /free

       Path=vvIn_char('PATH');
       File=vvIn_char('FILE');
       vvOut.download='Y';
       vvOut.file = File;
       vvOut.contentType = 'application/x-download';
       vvout.binary='Y';
       vvOut_file(Path:vvOut);

      /end-free
     p                 e

It works like a charm. Thanks for your help.
