Need Assistance With Fixing WW-4194
https://issues.apache.org/jira/browse/WW-4194
Please see the notes for WW-4194. I've not been able to figure out the
cause of the bug the user reported as I'm not too familiar with the
Component class and how the ValueStack object is created and provided to the
Component class constructor. I tried following the code for OgnlValueStack
but got a bit lost and I'm not sure I'm even on the right track.
What is also unusual about this bug is the findValue method correctly
returns null when used from within an Action class but does not work
correctly when used in a JSP that was generated by the component tag.
So any assistance in pointing me in the right direction for finding the code
that causes the bug described in WW-4194 would be great.

After unzipping the download create the .war file by using mvn -e clean
package
Then copy the .war file to Tomcat's webapps directory
Then go to: http://localhost:8080/Component_Tag_Struts2_Mvn/
Click on the link to Register
Complete the registration form and click submit
You will see two NOT NULL statements
The first NOT NULL statement should be NULL as the findValue statement in
the testcomponent.jsp (line 5) is being used to find an object that does not
exist in the ValueStack.

This can be related to WW-3990 but I cannot confirm it right now.

http://localhost:8080/thankyou.jsp is the right url? Accessing JSP
files directly isn't the best practise - if it worked, that was an
unexpected behaviour.
