Undefined index: ajax, while using ajaxvalidation, and the ajax form extension

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a GiixActiveForm
2. Enable ajax validation
3. Add the ajax form plugin or extension

What is the expected output?
The record is inserted or updated

What do you see instead?
A 500 error, saying Undefinde index ajax, in line 160 of GiixActiveForm

What version of giix are you using?
1.9.1

What is your stack (operating system, web server, DBMS, PHP version)?

Any relevant additional software (opcode cache etc)?

Please paste the stack trace and the error message.

Please attach your relevant source and configuration files and sql scripts.

Please provide any additional information below.
To solve this error, I just add one more condition in that if, which is "&& 
isset($_REQUEST['ajax'])" so it does not throws the error when note receiving 
the ajax parameter.
