Hi Kaj,

I think this is the right solution for you needs.  Otherwise you have a
method, setData, that requires that another method, setMetaData, be called
first in order for it to function correctly.  However, you don't have any
way of ensuring this other than the implementation of details of code you
have no control over.  That is brittle design which should be avoided.

I try to avoid having anything in the set methods called by
takeValueFromRequest (other than a straight assignment) for this reason.
It is sometimes necessary to set a flag when a value is changed so that
processing can occur at a later stage - before invokeAction or
appendToResponse.


Chuck
