There are two ways to handle an update to an attribute, and I think (if
I understood correctly) that you mentioned them both in your email:
=20
1) to re-read just before the value needs to be used and not to cache it
in an variable, or at least to re-read on a sufficiently frequent basis
in a thread, say, and update the cached variable
=20
2) to overwrite the sfReplaceAttribute method not only call the "super"
method, but also to look at the attribute to decide if some special
action needs to be taken - such as update a variable, or start a thread
to carry out some action, and so on.

Subject: [Smartfrog-support] Updating an attribute !


Hi,

I am wondering is it possible to update an attribute for an already
deployed component e.g. lets suppose in the component configuration I
have an attribute named "save" which is set to "false".=20

During the deployment process of component its being resolved, and the
value "false" is set to a local variable with in that component.

Then at later stage, if a user wants to update attribute "save" using
the managementConsole, and set its to "true".=20

Would following be the right approach to read the new value by simply
resolving the attributing again in a certain function to use the later
"save" value or the sfReplaceAttribute have to be called rather than
resolving the attibute!=20

Regards

Omer
