Howard M. Lewis Ship closed TAPESTRY-2079.
------------------------------------------
Resolution: Invalid
Assignee: Howard M. Lewis Ship
This is a known, documented and unavoidable side effect of the technology that
supports dynamic class reloading and class transformation.
Define an interface for the methods that are relevant to you utility code and
have the component class implement the interface. Make sure the interface is
not loaded by Tapestry's class loader, don't but it in the .pages, .components,
.mixins or .base sub-directory.
> Component class type is lost when it is passed outside Tapestry application
> pages or components package

>
> I obtain component container inside one component (e.g. call
> ComponentResources.getContainer()) and when i check the class type inside the
> same component method everything is ok but when i decide to pass the same
> component to an utility class that do the same there it fails.
> E.g. i have two methods inside my component class and the first one returns
> true, the second one false although the code should be the same for both
> (only different package/class):
> public boolean isInsideTestContainerLocally(){
> Component comp = resources.getContainer();
> return (comp instanceof TestContainer);
> }
>
> public boolean isInsideTestContainerWithCall(){
> Component comp = resources.getContainer();
> return Util.isInstanceOfTestContainer(comp);
> }
> ----->>----Util class contains the method---->----
> public static boolean isInstanceOfTestContainer(Component _comp){
> return _comp instanceof TestContainer;
> }
