trouble with vvUtility_getSessVar or is it a bug?

[ThierryC]

I'm writing an app to do an upload from an Excel -sheet, in order to get in converted into the correct layout for transfering data in our finance application.

after the upload, i want to show progress messages to the user,

After my upload (with submit) from the Xls, i launch an Rpg-program (FISUPLOAD) and after the success from the upload i also launch Ajax-calls in to know get the state of the progress.. with this ajax call i call another RPG (GETPROGRES)..

in the first FISUPLOAD i'm setting the progress by:

  vvUtility_saveSessVar(
            'PROGRESS':
            OC
             +DQ+'success' +DQ+COLON +%trim(successText)         +COMMA
             +DQ+'msg'     +DQ+COLON +DQ+%trim(messagetext)+DQ   +COMMA
             +DQ+'progress'+DQ+COLON +%trim(%editc(percent:'Z'))
          + CC:
            vvSessId); 

and in the GETPROGRES i'm doing a:

 vvUtility_getSessVar('PROGRESS':progressMsg:vvSessid); 

however the progressMsg in the latter is always blank..
i can see the progress directly in the VVSESSVAR-file, and also when i do logging, i see that my sessid is also correct... nevertheless the value remains blank..

In my js-program i now do the Ajax-call, with a setTimeout.. i'm pretty sure this is not the right way, can you also assist on what the best way is to launch Ajax-calls for getting a progress-state... ?? thx in advance..

if (uploadForm.isValid()) {
    uploadForm.submit({
        url: '/valence/vvupload.pgm',
        waitMsg: 'Uploading file...',
        success: function(fp, o) {
            Valence.util.msg('File upload', o.result.msg,2000);
            Ext.MessageBox.show({
                title: 'Please wait',
                msg: 'Uploading to FIS...',
                progressText: 'Initializing...',
                width:300,
                progress:true,
                closable:false,
                animateTarget: 'uploadbtn'
            });

            var f = function(v){
                return function(){
                    console.log('Calling Ajax Request : ' +v);
                    Ext.Ajax.request({
                        url: 'vvcall.pgm',
                        params: {
                            pgm: 'GETPROGRES',
                            action: 'getProgress'
                        },
                        success: function(response) {
                            if (response.responseText) {
                                var data= Ext.util.JSON.decode(response.responseText);
                                
                                if (data.success) {
                                    if (data.progress>=99) {
                                        Ext.MessageBox.hide();
                                        Ext.example.msg('Done', 'Data was uploaded to FIS!');
                                    } else {
                                        Ext.MessageBox.updateProgress(data.progress/100, Math.round(data.progress)+'% completed', data.msg);
                                    }
                                } else {
                                    Ext.MessageBox.hide();
                                    Ext.Msg.show({
                                        title:'Error',
                                        message: data.msg,
                                        icon: Ext.Msg.ERROR,
                                        buttons: Ext.Msg.OK
                                    });
                                }
                            }
                        },
                        failure: function(response, opts) {
                            console.log('ajax request failed' + response.status);
                        }

                };

I think the issue is simple - the vvUtility_getSessVar returns a value, but you're not receiving it.

Try this instead:
ProgressMsg = vvUtility_getSessVar('PROGRESS':vvSessid);

hi Robert..

now i noticed.. stupid of me...

My other problem i've asked ...could you still help me on the way on how the best practice is for sending Ajax- calls to get the progress

i've now (taken from an example) the setTimeout in a for-loop from 1 to 13...
how can i launch the ajax-requests, and let them stop depending on the progress-state?

for(var i = 1; i < 13; i++){ 
                console.log(i); 
                setTimeout(f(i), i*500); 
            }

For your progress bar, instead of having a for loop submit function "f" 13 times, I would suggest you replace that with a single call to function "f", and then in your Ajax 'success' clause if progress<99 then do the setTimeout to submit "f" again after a short delay. You probably don't need that "return function()" line either.
