SAPUI5: How to make an asynchronous OData .create() request?

[Former Member]

Hi,

In my sapui5 app, I have an animation made by progress indicator which is running while waiting for the response of an OData model .create() service. However, the animation stops after the request is sent.

Does anyone know how to make an async .create() OData request?

Thanks a lot!

My code look like this:

oODModel = new sap.ui.model.odata.ODataModel(myUrl);

oEntry = myNewDataEntry;

myAnimationIndicator.start();    //animation starts to run

var onSuccess = function(){myAnimationIndicator.stop();};

var onError = function(){myAnimationIndicator.stop();};

oODModel.create('myDataSet',oEntry, null, onSuccess, onError);

Hi ,

Please pass true in the call creat(sPath, oData, oContext?, fnSuccess?, fnError?, true) to make async request.

Thanks,

Hey,

You can give it a try with the below snippet which is working fine for me.

var onSuccess = function(){myAnimationIndicator.stop();};

var onError = function(){myAnimationIndicator.stop();};

var reqHeaders = {

                    context: this,// mention the context you want

                    success: onSuccess, // success call back method

                    error: onError, // error call back method

                    async: true // flage for async true

                };

// show the loader here

myAnimationIndicator.start();

oODModel = new sap.ui.model.odata.ODataModel(myUrl);

oEntry = myNewDataEntry;

oODModel.create('myDataSet',oEntry, reqHeaders );

Hi, I would like to ask a question about your solution.

What is context: this for? I am not very sure what the context is for and what object this is supposed to be.

According to the SAPUI5 documentation:

• [FEATURE] ODataModel: Support for asynchronous Create/Update/Remove

Was not released until Version 1.20

[former_member182372]

try to place odatamodel.create in

window.setTimeout(function() { <HERE> }, 100);

Hi there,

This issue still not solved. Anyone has ideas? Override create method or?

Thanks.

Why not update your UI5 version ?

Hi Sakthivel,

Could you kindly povide the link to the sapui5 version you mentioned? I cannot find 1.19.1, and your old link does not work either. The official one is 1.18 only?

Thanks a lot.

Hi Dong,

1.18 supports that feature, as you can see here: SAPUI5 SDK - Demo Kit

And download is available here: OpenUI5 - Download

Hi,

Now I have updated sapui5 to 1.18.10, but the progressindicator animation is still not running while waiting for the resp, though I set async for .create() req. Has anyone tried similar thing before?

The animation is started by calling a function, say, startIndicator(), which actually running in an infinite loop showing the moving progress bar. I wonder teh problem is due to the way how to start the indicator while sending the req.

Thanks.

Hi Dong,

I'm not sure if the parameter is for asynchronous request for the "real data", since it's called "bLoadMetadataAsync". I guess it's only for the metedata document to be loaded asynchrone - but maybe somebody else can say more.

Hi Ben,

Thanks for the tip. I will dig into it and hopefully someone else would come up with some ideas.

Hi,

try

oODModel.create('myDataSet',oEntry, null, onSuccess, onError,true); //true sets asyn

The last paramter is a boolean, which decides to be async or sync.

Hi Sakthivel,

Thanks for the quick reply. But I looked the API:

    creat(sPath, oData, oContext?, fnSuccess?, fnError?)

    Trigger a POST request to the odata service that was specified in the model constructor.

which does not seem to have a flag bAsync param. Anyway, I will have a quick try.

Hi Dong,

I'm referring to the UI5 1.19.1 Version. Here's the API

http://veui5infra.dhcp.wdf.sap.corp:8080/demokit/#docs/api/symbols/sap.ui.model.odata.ODataModel.htm...

Hi Sakthivel,

I am using SAPUI5 1.14.6, no wonder why the API is different. Thanks very much for the info.

By the way, can you paste the API lines of .creat() method? I cannot open the site now. Just want to see the details of the method.

Br,

Dong

P.S:

@SAP: I sincerely hope the latest changes of API can be reflected on the official website which we developers use serioesly. Thanks very much in advance!
