Re: T5: help required: Context and PageLink

[Andy Pahne]

In your second example, "5" is interpreted as String.

In your first example, I am not sure. What type is 
listItem.metadata.metadataId? Maybe it is not long?

I have a PageLink thus:

<t:PageLink t:page="viewMetadata" t:context="listItem.metadata.metadataId">
  &gt;
</t:PageLink>


and code thus:

public void onActivate(long metadataId)
{
        System.out.println("METADATA ID = "+metadataId);
        this.metadata = repository.getMetaDataById(metadataId);
}


Although every time I click on the link I get taken to the correct page 
and the passed value is printed out correctly, I also get the following 
exception:

[ERROR] TapestryModule.RequestExceptionHandler Processing of request 
failed with uncaught exception: Exception in method 
dportal.pages.ViewMetadata.onActivate(long) (at ViewMetadata.java:20), 
parameter #1: Coercion of style.css to type java.lang.Long (via String 
--> Long) failed: For input string: "style.css"
org.apache.tapestry5.runtime.ComponentEventException: Exception in 
method dportal.pages.ViewMetadata.onActivate(long) (at 
ViewMetadata.java:20), parameter #1: Coercion of style.css to type 
java.lang.Long (via String --> Long) failed: For input string: "style.css"


This occurs even when hard-coding the value thus:

<t:PageLink t:page="viewMetadata" t:context="5">
  &gt;
</t:PageLink>


So, what have I done wrong?
