In script error it is showing error in ext-all.js. what may be the problem when showing "this[a] has no properties" in firefox script errors? please help me to complete this task.
A:
This usually happens when you refer to an object/widget which is not yet being rendered (But you suppose it to be).

A:
Use the ext-all-debug.js version of Ext to get a better error message. The Ext JS library ships with two files which contain the library (ext-all.js and ext-all-debug.js)
ext-all.js has been run through the YUI Compressor tool and has removed all whitespace, line breaks and comments. YUI compressor will also rename variable names to short versions like "a".
If you use ext-all-debug.js you will receive a better error message.
