Parameter has already been declared
Someone here has an application where he's getting the following
exception:
Caused by: org.apache.hivemind.ApplicationRuntimeException: Parameter
onLoad has already been declared (at Annotation
@org.apache.tapestry.annotations.Parameter(cache=true, defaultValue=,
required=false, name=, aliases=) of public abstract java.lang.String
com.ifactory.sageeref.component.HeadContents.getOnLoad()). [Annotation
@org.apache.tapestry.annotations.Parameter(cache=true, defaultValue=,
required=false, name=, aliases=) of public abstract java.lang.String
com.ifactory.sageeref.component.HeadContents.getOnLoad()]
at
org.apache.tapestry.spec.ComponentSpecification.addParameterByName(ComponentSpecification.java:245)
at
org.apache.tapestry.spec.ComponentSpecification.addParameter(ComponentSpecification.java:227)
at
org.apache.tapestry.annotations.ParameterAnnotationWorker.performEnhancement(ParameterAnnotationWorker.java:68)
at
org.apache.tapestry.annotations.AnnotationEnhancementWorker.performMethodEnhancement(AnnotationEnhancementWorker.java:142)
... 93 more
He says that he only gets this when it runs in jetty and not when it
runs in tomcat although I haven verified that. Here's the page class
that it's complaining about:
public abstract class HeadContents extends BaseERefComponent {
public abstract String getStylesheet();
@Parameter
public abstract String getPageName();
// SEEMS TO BE COMPLAINING ABOUT THIS
@Parameter
public abstract String getOnLoad();
@Parameter
public abstract String[] getScriptFiles();
@Parameter
public abstract String[] getStylesheetFiles();
public String getPageTitle(){
...
}
}
Anyone have any suggestions as to what the problem could be? Thanks!

This also sounds like an old bug that hit people only when caching was
disabled. It's been fixed starting with 4.1.1.

try changing string[] to Collection<String> and see if this changes
anything, tapestry is probably able to coerce these values, isn't it?
Cheers,
