[EP-tech] Re: Can_call for nested config

OK - it looks like the can_call works OK, but actually calling (with some data) it doesn't.
Doing this:

if ( $repository->can_call( 'ethos', $institution, 'thesis_type_match' ) ){
	print "CAN CALL!\n";
	print $repository->call( 'ethos', $institution, 'thesis_type_match', 'some data' );
}

Results in:
CAN CALL!
Undefined or invalid function: ethos

Any clues?

Cheers,
John

Hi,

I've copied / pasted your example which just works on my local 3.3.9 
install.

Try debugging perl_lib/Repository.pm::can_call and see where it fails.
