Calling Customer Controls from POJOs

Hi,

 

I'm writing a web application (WLP 9.2) which has a
scheduler component to it. I'm trying to call a custom
control from a POJO that the scheduler calls. But whenever i
call a method on the control I always get a NPE, even though
all the correct annotations are present. All the necessary
control generated files are created, but it would just seem
at runtime that the JVM doesn't have any idea of this and
never instantiates the control.

 

Is there some 'hook' i'm missing, or can controls only be
called from within the beehive framework - pageflows and
other controls.

 

Thanks in advance.

Hi Anthony,

While it is possible to use some Beehive controls directly
from a POJO
it is not a use case we support.

If your custom control does not contain any 'Context'
annotations you
may be able to use it from a POJO.  You will need to
instantiate the
control using programmatic instantiation, see:

http://beehive.apache.o
rg/docs/1.0.2/controls/programming.html#Programmatic+Instant
iation

in the Beehive documentation.  You won't get any lifecycle
events or
have access to any resource from a control container context
when
using the control from within a pojo.
