    Default MVC Form submit changes to the server using direct proxy

    MVC Form submit changes to the server using direct proxy


    Hi to all,

    I'm developing an extjs application using MVC pattern.
    I have a form with a store defined like this

    Code:
    // The new DataWriter component.
    var writer = new Ext.data.JsonWriter({
                encode : false
            });
    
    
    Ext.define('AM.store.nwkview.NwkPanel1', {
                extend : 'Ext.data.DirectStore',
                requires : 'Ext.direct.*', // use ext-direct for binding
                /**
                 * The model of the data of the store
                 */
                model : 'AM.model.nwkview.NwkPanel1',
    
    
                autoLoad : true,
    
    
                constructor : function(config) {
                    config = config || {};
                    config.proxy = {
                        /* Accept direct methods */
                        type : 'direct',
                        extraParams: {'networkId':0},
                        paramOrder:['networkId'],
                        /* API interface */
                        api : {
    
    
                            read : NetworkView.getPanel1,
                            update : NetworkView.updateNwkConfig
                            // destroy : undefined
                        },
                        /* The reader and the writer */
                        reader : {
                            type : 'json',
                            root : 'result'
                        },
                        writer : writer,
                        paramsAsHash : false
                    };
    
    
                    this.callParent([config]);
                },
                
                load : function(record) {
                               ....
                               ....
                }
            });
    Now, Is it possible to call the store update function from the component's controller to submit it to the server side?
    This is the way I found in some documents across the web but store.sync() won't call the server method specified:

    Code:
              init : function() {
            console.log('init function in panel Controller has been called... ');
            this.control({
                'editpanel[store="nwkview.NwkPanel1"] >> tool[type="save"]' : {
                    click : function(th, e, eOpts) {
                        var store = this.getStore("nwkview.NwkPanel1");
                        debugger
                        store.sync();
                    }
                }
    
    
            });
        }
    My server method is the following:
    Code:
    @DirectFormPostMethod
        public void updateNwkConfig(Map<String, String> formParameters, 
      Map<String, FileItem> fileFields) throws Exception {
            
            WebContext context = WebContextManager.get();
            if(context==null)
                Utils.ERROR_WEBCONTEXT_NULL("Network View", "updateNwkLabel");
    
                  log.info("CALLED!");
    I tried also:

    Code:
    @DirectMethod
        public void updateNwkConfig(JsonElement newlabel) throws Exception {
            
            WebContext context = WebContextManager.get();
            if(context==null)
                Utils.ERROR_WEBCONTEXT_NULL("Network View", "updateNwkLabel");
    
                   log.info("CALLED!");
    }
    but this won't work too

    Any suggestions?

    Thanks for your help.

    The sync method is the correct means. Is there any actual changes in the store to send?
