Hi @Jeeva-Rathinam ! Could you also provide please your xml config for rewrite?

[Jeeva-Rathinam]

@northdakota My : app\etc\modules\Eltrino_DiamanteDesk.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Eltrino_DiamanteDesk>
            <active>true</active>
            <codePool>community</codePool>
        </Eltrino_DiamanteDesk>
    </modules>
</config>

How can i solve the issue?

[northdakota]

As i understand you have created a new block file Eltrino/Diamantedesk/Block/Adminhtml/Sales/Order/Edit/Tab/Tickets.php for make it works you also should add your rewrite configuration to file app/code/community/Eltrino/DiamanteDesk/etc/config.xml where should describe your rewrite configuration. For example:

<blocks>
    <catalog><!-- alias of the block group you are rewriting -->
        <rewrite><!-- reserved tag: specify that you are rewriting something -->
             <class_name_here>YourNamespace_YourModule_Block_Your_New_Class_Here</class_name_here> <!-- tag: the rest of the alias of the class you are rewriting. value: the name of your class that rewrites the core class -->
        </rewrite>
    </catalog>
</blocks>

So i need make sure that this part of your code is correct.

Yes, app/code/community/Eltrino/DiamanteDesk/etc/config.xml (By Default) Here what i need to change...
