Re: Need help with triggers

I had tried session.find(). But when I run my gfd I get an error message
saying it cannot find metadata. Both these classes belong to a module called
'crm'. i tried the following:

customerIndex = session.find(crm_metadata)
customerIndex = session.find(metadata)

I get the same error.

NameError: name 'crm_metadata' is not defined
NameError: name 'metadata' is not defined

Also while we are at this I had another query. How can I delete entries from
a detail class from an OnDelete trigger on the master class.
