[jira] Commented: (TAPESTRY-2079) Component class type is lost when
it is passed outside Tapestry application pages or components package
[ https://issues.apache.org/jira/browse/TAPESTRY-2079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12563443#action_12563443 ]
Priit Karu commented on TAPESTRY-2079:
--------------------------------------
It is the other way around. My components call code that are in the utility classes (and pass some parameters from the components).
How could i avoid code duplication if i can not pass classes from components to utility classes safely? Any ideas?

> 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;
> }
