How to call bean method when drag-drop the element using <p:pickList>?

Question

I am using primefaces 3.3 library for jsf based application.

I am using <p:pickList> to handle drag and drop the element from source to target and vide versa.

I want to call the jsf bean method when element transferring(by drag-drop ) from source to target and vice versa and handle some logical things there.

I follow the link PrimeFaces showcase for pickList to implement my functionality. This is the version 5.2.7.

In primefaces 5.2.7 it can be easily done by <p:ajax event="transfer" /> , but how can I achieve this using primafaces 3.3.

I try valueChangeListener attribute but it is not working. There is one attribute called onTransfer , but it is for clientSide callback.

This can be achieve by putting submit button. But I want to achieve it on drag and drop. So how can i do that ?

Thanks in advance.

First, you should consider an update of your primefaces version. Updates are not only provided for new features but also for bug fixes, improvements (performance, stability) etc.

Currently I cannot find the documentation for 3.3, but what you could try is using p:remoteCommand (its in the 3.5 documentation, so maybe available):

use onTransfer="submitToBean()" along with a p:remoteCommand that might look like this:

<p:remoteCommand 
   name="submitToBean" 
   action="#{myBean.doSomething}"
   process="idOfYourPickList" 
   partialSubmit="true" />

Then the onTransfer Event will call the javascript method submitToBean() which in turn will process your picklist and call the action method.
