Matt Benson commented on MYFACES-2552: -------------------------------------- Also, spec issue #745 is considered resolved at this point. We just need to address it when we do the JSF 2.2 implementation in MyFaces. > TagValueExpression.getType() returns null if the property in the managed bean > is null and the expression points to a facelets composite component attribute > ----------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: MYFACES-2552 > URL: https://issues.apache.org/jira/browse/MYFACES-2552 > Project: MyFaces Core > Issue Type: Bug > Components: JSR-314 > Affects Versions: 2.1.0 > Reporter: Jakob Korherr > Assignee: Jakob Korherr > Attachments: MYFACES-2552-spec-proposal.patch > > > if you have a facelets composite component with an attribute "test" that > points to a property in a managed bean (e.g. #{myBean.property}) which is > currently null and you refer to that attribute in the implementation via > #{cc.attrs.test} you can get the current value (null) or set a new value but > you cannot get the type of the property (e.g. String[]). However if the > property in the managed bean is non-null you can get the type. > For example: > <cc:interface name="mycomponent"> > <cc:attribute name="test" required="true"/> > </cc:interface> > <cc:implementation> > <h:selectManyListbox value="#{cc.attrs.test}"> > <f:selectItems value="#{some select items}"/> > </h:selectManyListbox> > </cc:implementation> > --> calling #{cc.attrs.test}.getType() will fail if #{cc.attrs.test} resolves > to null, but will work if #{cc.attrs.test} resolves to some valid value. > This currently results in a NullPointerException in > _SharedRendererUtils.getConvertedUISelectManyValue(). -- This message is automatically generated by JIRA.
