Hi Team,
I have integrated esri with extjs-4.2. I am getting the map element in the proper size for the first time when the screen loads.However i am not getting the map element in the proper size when trying to reload the map element alone. The map element is getting reset to 400*400 automatically, which am not able to change. Please find below supportive screenshots with following code.
Here the piece of code intiating the Map in Extjs.
Ext.getCmp('dashboardcontainer').add(Ext.widget('mapPanel'));
