Hi,

I am looking for a solution to reset the properties of a session scope managed bean to the default values I specified in faces-config.xml (<managed-property>). I want to use this in a "reset to default" command button.

Any help would be appreciated!

Thank's and best regards
Klaus

Can't you just remove the session bean from scope. The next time it is referenced it will be recreated.

Thanks for advice. Your solution resolved parts of my problem.

My problem is, that the action which should reset the bean properties is an action on the bean which I want to reset

<h:commandButton value="#{msg.reset}" action="#{invocation.reset}" immediate="true" />

The action-code



did reset the bean-properties but obviously not the components (values) which were bound to the properties. So I had to reset the components to (otherwise the old values were displayed afer render response).

The code



did it finally. Im not sure if this is the way to do it.

I am also a bit confused about the relationship between bean-property-values and component values and wether a change of the one side affects the other side. Changing the bean property in code does not necessarily also changes the components value seen on the jsp-Page. Any explanation on this topic would be helpfull for me.

Thanks anyway!

Hi Klaus,

I had the same problem a while ago.
It turned out that the answer is supersimple: Just reset the attributes you want to refresh.
Or am I missing out something?
