I have upgraded by website from magento ce 1.4.2 to magento ce 1.7.2, everything works fine but custom customer attributes in account edit page are not getting saved, I have added these attributes using my custom module.  

What can be the probable issue.   

I have done a little debugging that shows I am not getting my custom attributes in `$this->_attributes;` in `getAttributes()` method.  

Please let me know if anybody have any idea or someone faced any similar issue and what he/she have to fix it.
