Summary: PPR issue with IE Security "High" in Zone "Internet"
Key: TRINIDAD-2317
URL: https://issues.apache.org/jira/browse/TRINIDAD-2317
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components, Facelets
Affects Versions: 2.0.1-core
Environment: Windows XP/7, IE 8/9, Tomcat 6.0.30
Reporter: Volker Malzahn
After setting security level of zone "Internet" to "High" in "Internet
Options/Security" of Internet Explorer 8 or 9 PPR requests don't function
correctly: first PPR request of a page is successful, but all subsequent
requests of same page don't function. I don't use JSF AJAX requests but good
old Trinidad PPR (org.apache.myfaces.trinidadinternal.PPR_OVER_JSF_AJAX in
web.xml is off).
Strange is that although my server is added to "Trusted Sites", which should
overwrite IE's security settings of zone "Internet", it seems that this
overwriting isn't done completely. (That it does it party is apparent because
JavaScript in general functions.)
I have debugged a little and found out following:
When processing the answer of the first PPR request In
TrPage._handlePprResponseFragment the statement
"targetNode.parentNode.replaceChild(sourceNode, targetNode)" seems to cause
that all subsequent PPR requests don't start processing in IE: a breakpoint in
_submitPartialChange or formSubmit isn't reached. Same happens if I change the
code to explicitly add the new node and remove to old one. Adding a new node to
the DOM tree seems to be the critical point.
In a test I have replaced "targetNode.parentNode.replaceChild(sourceNode,
targetNode)" by "targetNode.outerHTML = sourceNode.outerHTML" if browser is IE,
and this seems to fix the issue for my webapp.
Wouldn't it be best to do this change (for IE) in Trinidad's JavaScript code?
Or do you know another solution for this issue?
Regards,
Volker
