CommandLink does not execute action if no javascript is allowed
---------------------------------------------------------------
Key: MYFACES-1692
URL: https://issues.apache.org/jira/browse/MYFACES-1692
Project: MyFaces Core
Issue Type: Bug
Components: General
Affects Versions: 1.2.0
Environment: Tomcat 6.0, javax.faces.STATE_SAVING_METHOD=server,
org.apache.myfaces.ALLOW_JAVASCRIPT=false
Reporter: Thomas Fischer
Situation:
The tag <h:commandLink action="#{someBean.someAction}"
value="submit"></h:commandLink> is used in a jsp page, which is visited by the
user. The user clicks on the link.
Expected behaviour:
The method someBean.someAction() should be called, and the navigation rule
which matches the outcome should determine the page to be displayed.
Wrong behaviour:
The method defined in action is not called and the same jsp page is rendered
again.
I did some debugging to find the reason of this problem. It seems to me that
the server does not recognize that the click on the link is a postback. In line
172 in org.apache.myfaces.renderkit.html.HtmlResponseStateManager, the HTTP
Parameter ResponseStateManager.VIEW_STATE_PARAM is checked for existence. If it
is there, the request is a callback, and if it is not there, the request is not
treated as postback. This parameter is not encoded in the link rendered by
h:commandLink, thus the request is not treated as a postback, and the page is
just rendered again.
If javaScript rendering is allowed, this works fine because the HTTP parameter
ResponseStateManager.VIEW_STATE_PARAM is rendered as a hidden input field, and
the javascript code does a form submit.
It seems to me that the problem could be solved by adding the parameter
ResponseStateManager.VIEW_STATE_PARAM to the generated link (but I did not
check it).
