Tarun,

Do you have an onRecieveData function in your Labelwidget?

Here I would have my visiblelayerwidget:

startup: function(){
  this.inherited(arguments);
  // this is so you can catch any communication that occured before your widget started up
  this.fetchData();
  ...
},

onReceiveData: function(name, source, params) {
  if (params && params.target === "Labelwidget") {
    //do something with params.data
  }
},‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

hi robert,

Thanks for the support,i have doubt is it possible to use below method more than once in single widget?

this.publishData({
'target':"Labelwidget"
'data': currentWidget.publishObj
});

Example:

this.publishData({
'target':"Labelwidget"
'data': currentWidget.publishObj
});

this.publishData({
'target':"searchwidget"
'data': currentWidget.publishObjects
});

please check the above example ,if it is possible using publish data more than once in single widget please let me know

Tarun,

Not sure why you would want to since your data property can be an object with multiple properties (i.e. and object that has multiple objects). As far as I know yes you can call publishData as much as you want though.
