Bug ID: 62376
Summary: PropertyNotFoundException since 8.5.25
Product: Tomcat 8
Version: 8.5.x-trunk
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: EL
Assignee: dev@tomcat.apache.org
Reporter: msadow...@novomind.com
Target Milestone: ----
Upgrading from Tomcat 8.5.24 to 8.5.31 we encountered a lot of
PropertyNotFoundException's. I nailed it down to this change:
https://github.com/apache/tomcat/commit/b7ce5679b9e6a073dadbc31e6ecde12ad1e0ede8#diff-5dfeea95029bca0c6f37f20eeb4940a4
With this change you now compare the paramCount with the passed values which
didn't happen before.
I believe that line 186 should be: "if (m.isVarArgs() ...)" (no "!").
We only see these errors when using f:ajax or p:ajax wrapped by composite
components which define the listener as an attribute. Perhaps my issue in
Primefaces can help: https://github.com/primefaces/primefaces/issues/3659
When debugging this issue I also found, that Mojarra
(https://github.com/javaserverfaces/mojarra/blob/2.2.16/jsf-ri/src/main/java/com/sun/faces/facelets/tag/jsf/core/AjaxHandler.java#L460)
and Primefaces
(https://github.com/primefaces/primefaces/blob/master/src/main/java/org/primefaces/behavior/ajax/AjaxBehaviorListenerImpl.java#L64)
are expecting a "MethodNotFoundException" but a "PropertyNotFoundException" is
thrown because of
