Re: [S2] ExecuteAndWait Interceptor // Only re-submit token parameters on refresh?

[Burton Rhodes]

Yes. I believe this is the case. Let me see if I can track down an example
that breaks. Right now I just have reports of this happening but I haven’t
been able to reproduce on my end yet.

Also, How would I include everything except the email body field with the
s:url tag?

Thanks,
Burton

Could you try including all except the email body field? I guess this
issue happens because the email body usually is too long to being
included inside url query string. To confirm, could you increase refresh
timeout to have time to right-click on your browser page then click view
source? I'm interested what is generated by "/> there when there is a
long email body posted!

Thanks in advance!

Re: Struts2 login action class seems to be reused

[Prasanth Pasala]

Finally we redeployed the code with an added check to make sure the instance 
variables populated by struts match the request parameters. With in few hours 
of deployments we got emails indicating that
the values populated into the instance variables don't match those in request 
parameters. Below you can see the difference between the instance variable and 
the values in the request object.  The code
is also updated to store the hash code of Login action for each login, so that 
we can see if the object is reused. Surprisingly the hash code doesn't match 
with any of the hash codes stored for
successful logins. When the emails are triggered there is only a GET request 
for the Login action (which should display the login page, on the user enters 
the username & password it is submitted via
POST). So I am wondering where did these values come from into the instance 
variables?

-
Struts data doesn't match that in request object.
Struts Data:
    Username: jsmith
    Action: Login
Request Data:
    Username: null
    Action: null

Object Hash: 1573857416

It seems you don't need to extend Struts textfiled as Struts already
supports both validations and formats. Just search "Struts regex
validation" and "Struts textfield format" :)

Unfortunately, it seems Struts doesn't have any further component for
more than two selects (3, 4, 5, ... n dependent selects). However, you
can use java-script as advised (Strut's doubleselect also generates
java-script for client). Or more harder but nicer and cleaner, you can
review current Strut's doubleselect implementation and see if you can
improve it to accept N sequentially dependent selects! Then you can try
a share/merge into Struts :)
