Unanswered: Extjs3 to Ext4 migration
We are migrating MVC application from Extjs3 to Extjs4
Below are the steps we followed.
1) AddedExt JS 3 Compatibility Layer2)Added ext3-compat.js and ext3-core.compat.js files reference
3) Added Extjs4 reference
4) Removed the Extjs3 reference
5)Changed Ext3 grid(with paging toolbar) to Ext4
This results in the below output:
An Empty screen --The UI cannot be seen.
Exceptions thrown are :
1."Ext is not defined" in ext3-compat.js at
if (Ext.toolbar && Ext.toolbar.Toolbar)
2."Ext is not defined" in ext3-core-compat.js at
Ext.Compat = function() in ext3-core-compat.js
Could you please help to resolve this
