Hi friends,

When i inherit the code of account_voucher class it shows the error in following lines:

 res = super(account_voucher, self).fields_view_get(cr, uid, view_id=view_id, view_type=view_type, context=context, toolbar=toolbar, submenu=submenu)

In terminal it shows error like:

for key, val in sel:
ValueError: too many values to unpack

 

Post your full code and error log. This error is commonly raised when you have the wrong xml reference to the inherited form in your xml file.
