Tomcat 6.0, javax.faces.STATE_SAVING_METHOD=server, org.apache.myfaces.ALLOW_JAVASCRIPT=false
Description
Situation:
The tag <h:commandLink action="#
" 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).
