Magento Fatal error: Call to a member function setStoreId() on a non-object in /app/code/community/Magestore/Bannerslider/Block/Adminhtml/Bannerslider/Edit/Tab/Form.php on line 32

just comments below code:

Like as : //$model->setStoreId(Mage::app()->getStore(true)->getId());

 

Hope it will work.
