Hmm, that should not be possible, CreateObject will either throw an exception or return the instantiated class, it can not return NULL. You must miss something …
CreateObject('etemplate.etemplate') instantiate to old eTemplate class from the deprecated, and by default NOT installed
etemplate app. You either have to install it and it dependency the old API (
phpgwapi), or migrate to new Api\Etemplate class, which is mostly compatible.
I have no idea about that function, not aware it’s provided by either the old nor our current API.
Searching for it, I found only one reference to it’s name in the old translation-tools:
So it probably existed at some point in time, but not anymore.
