Magento Grid Container Block not loading grid

Question

I just set up an admin module with a grid view using the module creator, and it works great, but now I need to add another grid view within the same module.

Answer 1

In the grid container block look at the values for $_blockGroup and $_controller. These are used by the container to find and load the grid block. If you really want to see what is going on look at the parent::_prepareLayout() method.

PS:
$_blockGroup is your module's name.
$_controller is the path to your grid block.

PPS:
If that's not enough put this in your .htaccess:

php_flag display_errors on
SetEnv MAGE_IS_DEVELOPER_MODE true

You should get a lot more information if the grid is having problems with it's collection's SQL or something.
