So if emailId is null you construct a new one, but if it is not null and
findByEmail() fails, it is still null.
java.lang.IllegalArgumentException: attempt to create create event with null
entity
When i tried to debug it I am getting user object in prepare() function i.e.
user is not null but when i check the same value in update method it comes
out to be null
<s:hidden name="emailId" />
<s:if test="email==null">
<s:submit value="Register" />
</s:if>
This generates <input type="hidden" name="emailId" value=""/>, right?
So it'll submit a parameter &emailId=, which will result in emailId not
being null, but rather being the empty string. The prepare lookup
fails, so user is still null.
Try these two fixes:
> <s:if test="%{email == null}">
> <s:submit value="Register" />
> </s:if>
> <s:else>
> <s:hidden name="emailId" />
> <s:submit value="Update" />
