# 20120825¶

• New module lino.modlib.vat.

• Discovered and fixed the following bug in lino.core.actions.ActionRequest:

A programmatic request (without HttpRequest) on a table with parameters didn’t fill default values into param_values.

This bug was discovered by the following code (in lino.modlib.ledger):

for jnl in Journal.objects.all():

• Another subtile bug fixed: lino.dd.inject_field() now does nothing when it is called for a Model whose app is not installed. Discovered by lino.modlib.accounts where it wouldn’t be intuitive to require the application developer to check whether products is installed before calling inject_field.
