Can anyone tell me why sync does not send any json data to server ?

The problem is that you have only specified the transport.update method. You are creating a new item which uses transport.create instead of transport.update.

I am using Vb 2010 in designing my apps. I've connected my database with my application but I didn't use any code in the connection. I used Data source and Databinding property and when I save the data the database is always empty. Please help me with a solution.
Place a BindingNavigator component in your form and set it's binding source property to the same datasource of your other component.
I am new to eventBus() function in SAPUI5.
I am using eventBus.publish() in Table.view.js controller to publish data & have used eventBus.subscribe() in MainPage.view.js controller. It is working fine.
But while I try to implement eventBus.subscribe() in another controller ("Feed.view.js"), it is not working. Why is it so?
The cause of you problem is likely one of the following:
You are not using the same EventBus in all cases (e.g. in one case
you use the sap.ui.getCore().getEventBus(), and in another case you
use your component's oComponent.getEventBus())
You are not using the same channel
You are not using the same event ID
Please check this, and if it doesn't help post more of your code.
I've currently inherited an application which has numerous Kendo grids (and other controls) throughout, and I'm trying to fix an error which keeps cropping up now and again - specifically when the user is no longer authenticated.
I know what the solution is for a single instance of the control - return a flag to indicate authentication failed, and then detect this in the error handler and perform the authentication.
The problem is am I really going to have to handle this for every instance of a Kendo control I have? Is there not a global error handler I can hook into? Either for the data source itself (as I know this is used for all Kendo control data loading), or for the Grid specificially. I don't mind either way - just which one is a hook.
This would be a more straighforward short term solution than refactoring everything to specific error handlers, etc.
I assume you can attach a global error handler to $.ajax, which is used by the DataSource, you can check how to do it here:
http://api.jquery.com/category/ajax/global-ajax-event-handlers/
Or, you can take advanttage of that the configuration that is done in the DataSource is passed directly to the $.ajax:
http://docs.kendoui.com/api/framework/datasource#configuration-transport.read-ObjectStringFunction
For reference, someone from Telerik has provided a solution using just the DataSource. I haven't tested it, but I prefer the accepted answer above as it hooked into all Ajax on the site - not just ones that utilise the Kendo DataSource.

Is there a way in telerik openaccess to copy an object from one OpenAccessContext to another?
I tried the following (ugly) approach: Take an object of one context, serialize it, deserialize and then put it in another context.
I cannot believe that there is no build in method to just clone an object. Does anyone know a better way? (and i do not mean: copy using reflection)
You could use the Attach / Detach functionality of OpenAccess ORM to handle this scenario.
Have you used the old ObjectContainer approach, available in the Classic API or the latest OpenAccessContext.CreateDetachedCopy + OpenAccessContext.AttachCopy functionality? I am wondering which one has caused the troubles
Good day!
I used the Struts2 xml validation as instructed in this website.
The problem is when I clicked the submit button twice. The error message also appears twice...
My question is... how to clear the first error message before another action is processed to accommodate new set of error messages.
Thank you in advance.
If you are using the spring integration you have to define your bean as scope="prototype", then you get a new instance of your Action for every request.
The default scope for spring is singleton.
It's a good idea to do this for every Action.
Remove validate="true" from form tag.
There is a validator interceptor in the default stack. You just need to use that and using that is very simple. Just make a method in your action class by the name public void validate(). Within that validate() you can access the fields using their getters & then put the required validation onto them.
Also, with this implementation you would not have to worry about the multiple messages being shown, because it will show only the message what you set in the addFieldError method and removes any previously kept messages.
NOTE: Be sure to use getters of the variables in your validate(), because the variables in the action are not set at the time this interceptor is invoked.
Here is a link to a very nice tutorial.
http://www.vaannila.com/struts-2/struts-2-example/struts-2-validation-example-1.html
If you will keep validate=false, then validation xml will be called on submit action.
To clear messages on each submit click, if you are using table in your jsp then keep table outside of form. It will work.
