Hi,
Looks like this is a Seam, rather than ECM question. Basically, the
error message is saying that nothing is bound to any Seam context under
the name "myFileManager". You need to create one by some means, or have
Seam create it for you automatically. The Seam documentation should
help. Maybe all you need is to use the @AutoCreate annotation, but this
all depends on your own case.
Regards,
Sean
