[Helma-user] "Invalid Prototype Name"

[Paul Alexandrow]

Hi List,

Currently debugging an huge application I did not write, I'm greateful
for any help on the following log message, which I'm not able to
reproduce, but, according to the customer, occurrs repeatedly:

Invalid prototype Name: email - using default

I already dug into Helma's source where that Message originates, but was
not able to fully understand how things work there (basically the
extensionMap in the DbMapping class) in the time I had available.

My first - and unfortunately only - guess was, that this might come from
a db entry with the _prototype column set to "email", while no prototype
"email" is defined. This was not the case.

Any help on how this log message can be triggered is highly appreciated
as it would supply me with valuable information about what to search for
in the application I'm sitting on.

TIA,
Paul
