    ListGrid onRecordClick - Uncaught JavaScript exception

    Hi,
    I am trying to assign a cell value to a TextItem during onRecordClick of a ListGrid.

    Getting the error - Uncaught JavaScript exception [error has no properties] in http://localhost:8888/com.mycompany.HelloWorld/sc/client/debug/debug.js, line 281 from GWT.

    Am I missing something here. Can anyone help in resolving the issue. Thanks in advance.

    Code is as follows
    EntryPoint
    Code:
    package com.mycompany.client;

import com.google.gwt.core.client.EntryPoint;
import com.mycompany.client.sampledata.countryXmlDS;

      grid.setDataSource(countryDS);

      final TextItem myText = new TextItem("Country");

      grid.addRecordClickHandler(new RecordClickHandler(){

    The source data is in xml, so there's no way to know that you want to map your xml data to the Country class. So you cant cast event.getRecord() to your Country class.

    Code:
     grid.addRecordClickHandler(new RecordClickHandler(){
		public void onRecordClick(RecordClickEvent event) {    	  
			Country Message = (Country) event.getRecord();					
			myText.setValue(Message.getCountry());		
		}		
      });
    You could change the above code to

    Code:
     grid.addRecordClickHandler(new RecordClickHandler(){
		public void onRecordClick(RecordClickEvent event) {    	  
			ListGridRecord Message = event.getRecord();					
			myText.setValue(Message.getAttribute("countryCode));		
		}		
      });
    or

    convert the ListGridRecord to your County class object

    ListGridRecord record = event.getRecord();
    Country countryRecord = new Country(record.getJsObj());

    and add a constructor Country(JavaScriptObject jsObj);

      It works now

      Smartgwt.dev,
      Thanks, changed to the below code and it works.

      Code:
       grid.addRecordClickHandler(new RecordClickHandler(){
		public void onRecordClick(RecordClickEvent event) {    	  
			ListGridRecord Message = event.getRecord();					
			myText.setValue(Message.getAttribute("countryCode));		
		}		
      });

        Cast a ListGridRecord to other Class on DataSource

        And why not cast ListGridRecord to other Class on DataSource from @Override of :

        Code:
        protected void transformResponse(DSResponse response, DSRequest request, Object data) {

	ListGridRecord lgrA[] = response.getData();
	Country lgrB[] = new Country[lgrA.length];

	for(int i=0; i<lgrA.length; i++) {
		ListGridRecord lgr = lgrA[i];

		lgrB[i] = new Country (lgr);
	}

	response.setData(lgrB);

}
        If your Country class extends ListGridRecord, you can cast you data as you try in your first post.

            Type mismatch: cannot convert from Record to ListGridRecord

            Hi,



            For TreeGrid, inside onRecordClick(), this command
            ListGridRecord record = event.getRecord();

            compile OK on SmartGWT 1.0 (release 391)
            but fail on SmartGWT 1.1 with error message:
            Type mismatch: cannot convert from Record to ListGridRecord

            Anyone has similar problem ?

              Simply change
              ListGridRecord record = event.getRecord();
              to
              ListGridRecord record = (ListGridRecord) event.getRecord();

              seem fix the issue.
