AdvancedArBehavior conflict / error

[Nicolas400 (Nicolas Machado)]

Hi, I added AdvancedArBehavior to add some functionality to some models.

But I have this error when i try to export data to excel with EExcelView extension.

Fatal error: method_exists() [function.method-exists]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "CAdvancedArbehavior" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition in C:\xampp\htdocs\yii-1.1.12\framework\base\CComponent.php on line 558

If I remove the lines in the model, it works.

I want to know how can I fix this.

Best Regards.

PHP: 5.3.1
