Unable to clear data from Simple Table

[Kanugula]

Hi there,

qooxdoo 0.7.3
IE 6, FF3

I have the following code for a qx.ui.table.model.Simple implementation.

this.getTable().getTableModel().setDataAsMapArray(result); //result is null in case of no data.

I refresh the data using a qooxdoo button which calls the above code.

Whenever there is no data, I still see the old data.

Do you know why?

<code>
    _loadData : function()
    {
  var rpc = new qx.io.remote.Rpc(this.getTable().getTableModel().getServiceUrl(), this.getRpcService());
                 
        this.info ('Loading row data');  
        that = this;
                               
        var _handler = function(result, exc) {
                if (exc == null) {
     if (result != null) {    
                        that.getTable().getTableModel().setDataAsMapArray(result);
             }
             else
             {
                 that.getTable().getTableModel().setDataAsMapArray(result); //this doesn't work
                                 //do some more
             }
                }
            else
            {      
                        that.info("Exception from the server: "+exc);
            }
        };
        rpc.callAsync(_handler, myMethod, mydata);    }
</code>

Thanks.
Kanugula.

Don't pass in null if there is no data, pass in an empty array.

this.getTable().getTableModel().setDataAsMapArray([]);

that will clear the data.
