I made a module and has been registered too.. Its working completely fine until I wanted to create a custom grid...I have the below code written in the necessary files, but an exception is thrown that I have invalid block type specified. I ahve gone through it many times but I could not figure out the mistake.
/home/vhost/_default/magento1.9.2/app/code/local/Maven/Questionanswer/Block/Adminhtml/Questionanswer
<?php
class Maven_Questionanswer_Block_Adminhtml_Questionanswer_Question extends Mage_Adminhtml_Block_Widget_Grid_Container
{
public function __construct()
{
$this->_blockGroup = 'questionanswer';
$this->_controller = 'adminhtml_question';
$this->_headerText = Mage::helper('questionanswer')->__('questionanswer');
$this->_addButtonLabel = 'Add Question';
parent::__construct();
}
}
?>

$this->setCollection($collection);

I have also created a blank helper...where am I going wrong?
It seems your directory structure is not proper according to Grid block. Please follow below steps to fix your issue:
Step 1: Relocate your Grid.php file from:
/home/vhost/_default/magento1.9.2/app/code/local/Maven/Questionanswer/Block/Adminhtml/Questionanswer/Questionanswer
to
/home/vhost/_default/magento1.9.2/app/code/local/Maven/Questionanswer/Block/Adminhtml/Questionanswer/
Step 2: Change your grid class name from:
Maven_Questionanswer_Block_Adminhtml_Questionanswer_Questionanswer_Grid
to
Maven_Questionanswer_Block_Adminhtml_Questionanswer_Grid
Step 3: Clear your Magento cache and try to run load the grid page.
Updates:
Please change:
$this->getLayout()->createBlock('maven_questionanswer/adminhtml_questionanswer_questionanswer_grid')->toHtml());
With
$this->getLayout()->createBlock('questionanswer/adminhtml_questionanswer_questionanswer_grid')->toHtml());
As you declared your block as questionanswer rather than maven_questionanswer.
