If this is the case, does this mean that any form which is set to session scope in the struts-config.xml
file will have its reset() method called each time it is used by an action?Ie, If I have
<action path="/test1"
type="TestAction"
scope="session"
name="messageForm"
parameter="add"
</action>
<action path="/test2"
type="TestAction"
scope="session"
name="messageForm"
parameter="del"
</action>
And /test1 is called, the user enters data into the form and the data is saved in the messageForm bean which is saved. Later, the user
calls /test2, will the reset method in messageForm be called?
Cheers

If you have both of these actions defined as session scope, then I don't believe a new ActionForm would be created during the second action. If the mapping is session, then an ActionForm will be looked for in the session, which should have been put there on the previous action (along with the Vector data in it still).

Posted by Keith Bacon <ke...@yahoo.com>.
It will indeed be called.
Ted posted advice on how to deal with this a few weeks ago - try to find it in the archives.
Basically reset() needs to know which form was submitted so it can reset only the fields on it.
