Magento override abstract block

Question

I need to override an abstract Block in Magento : app/code/core/Mage/Eav/Block/Adminhtml/Attribute/Edit/Options/Abstract.php

I need to add a function to this class similar as getOptionValues for a specific product type.

I tried to override by adding the same structure (folder creations and copy the Abstract.php file) in app/code/local/Mage/Eav/Block/Adminhtml/Attribute/Edit/Options/Abstract.php, but it seems not working.

Anyone can help me ? Am I missing something ? Do I need to create app/etc/modules XML or the app/code/local/Mage/Eav/etc XML ?

Thanks a lot !

In order to override the app/code/core/Mage/Eav/Block/Adminhtml/Attribute/Edit/Options/Abstract.php
abstract class, you need to place the file as: app/code/local/Mage/Eav/Block/Adminhtml/Attribute/Edit/Options/Abstract.php which means your local pool path for Abstract.php is correct.

The only thing that i doubt why it's not loading is:
may be Compiler is enabled for your store(be sure to check from System > Tools > Compilation > Status should be Disabled).

Additionally check your log files(var/log/*.log) if there are any errors.
I would refer the following article for configuring your magento for development / debug mode:

Hope this helps a bit. Regards
