HtmlMessageRenderer evaluates value expressions of not rendered components
--------------------------------------------------------------------------
Key: TOMAHAWK-1494
URL: https://issues.apache.org/jira/browse/TOMAHAWK-1494
Project: MyFaces Tomahawk
Issue Type: Bug
Components: Message(s)
Affects Versions: 1.1.9
Environment: tomahawk12_1.1.9,
myfaces 1.2.8,
richfaces 3.3.3
jsp
Reporter: Michael Heinen
Priority: Critical
I produced a validation error in an inputText field. This field ha a
corresponding outputLabel component.
Now HtmlMessageRenderer creates a Map with all inputLabels, even if they are
not rendered at all.
This can result in exceptions because the value attribute of not rendered and
not initialized components is evaluated!
Sample content:
<t:div rendered="false">
<t:outputLabel id="abcabcLbl" for="abcabc" value="#{MyController.testme} "/>
<t:inputText id="abcabc" value="#{requestScope['test222']}"/>
</t:div>
Method MyController.getTestme() is called if messages are rendered although the
parent div component has attribute rendered=false
proposed fix:
if (root.isRendered())
should be added to method createOutputLabelMap.
Components should not be checked recursively if the root is not rendered at all.
