 Back
The situation occurs on a user account login information retrieval.  An action
class takes an email address to retrieve the data. If the email address is
incorrect for various reasons, the same screen/page will be redisplayed.

Other than a pair of getter and setter for the email address, there is only one
method, called doIt, to do email address validation and data retrieval.

Here is the problem I can't comprehend. When I enter  some characters, which is
not in valid email format, the doIt method is executed and an error message is
shown on the screen. Then, I type in an valid email format, but not in the DB.
The doIt method MAY not be executed.

This situation occurs when I have the class in the event scope, or in the
conversation scope and have the begin annotation with join=true on the setEmail
method and the end annotation on the doIt method.

Can someone points me to a right direction for this problem, please?
