parameter generic type not respected

[Paul Stanton <pa...@mapshed.com.au>]

Hi all,

I have a component with a parameter using a generic type eg:

public class MyComponent
{
     @Parameter
     private List<MyType> collectionParameter;
}

However I can set the parameter with a List of any generic type:

public class MyPage
{
     @Property
     private List<OtherType> otherCollection;
}

<t:myComponent collectionParameter="otherCollection" />

... and no exception is thrown.

Is this expected behaviour? Shouldn't the generic type be checked in 
this case?

Cheers, p.

Java generics are compile-time only.  They are lost at run-time,
Tapestry has no way to check this.
