Leonardo Uribe commented on MYFACES-3383: ----------------------------------------- I have checked the example provided, and unfortunately this is not going to work with the current strategy to resolve cc expressions. In few words, org.apache.myfaces.view.facelets.tag.TagAttributeImpl wraps every expression that resolve cc into a LocationValueExpression, and use the Location object to find the right instance. This hack has worked well so far but obviously fails in this case, because Location object is the same per composite component, and does not keep into account the position of the component in the tree, which is relevant in this case. This is a very, very rare use case. Solve this problem will not going to be easy. > Self nested Composite Component leads to EL Stack Overflow > ---------------------------------------------------------- > > Key: MYFACES-3383 > URL: https://issues.apache.org/jira/browse/MYFACES-3383 > Project: MyFaces Core > Issue Type: Bug > Affects Versions: 2.1.2 > Environment: Windows > Reporter: Michael Dietrich > Attachments: TestStackOverflow.war > > > If the same Composite Component is used inside itself, e.g. as child of an > ui:include that is included in the Composite Component, an StackOverflow > happens, if an EL Expression is refering CC interface attributes. > The use case is a CC to include a facelet, given by name. If the included > facelet uses the same CC to include another facelet, > "CompositeComponentELUtils.getCompositeComponentBasedOnLocation(..)" does > always find the same CC, which leads to an endless loop. > Please see the attached file for an example of the issue. -- This message is automatically generated by JIRA.
