Protected methods on Seam components
Hi all,
If I have a protected method in some circumstances on a Seam component I get an error when the method is called via a cglib proxy.
I get this exception thrown out of the cglib MethodProxy class.
throw new IllegalArgumentException("Protected method: " + sig1);
The class structure involved..
@Scope( ScopeType.STATELESS )
public abstract class ScreenActionComponent
{
public abstract void execute( ScreenActionMetadata screenActionMetadata, ScreenActionContext screenActionContext );
public abstract ScreenActionMetadata[] getScreenActionMetadata( ScreenActionContext screenActionContext );
}
public abstract class SingleItemScreenAction extends ScreenActionComponent
{
public final void execute( ScreenActionMetadata screenActionMetadata, ScreenActionContext screenActionContext )
{
execute( screenActionContext );
}
public final ScreenActionMetadata[] getScreenActionMetadata( ScreenActionContext screenActionContext )
{
if ( isValidSelection( screenActionContext ) )
return new ScreenActionMetadata[]{ new DefaultScreenActionMetadata( getDisplay(), getTooltip(), getImage() ) };
else
return new ScreenActionMetadata[ 0 ];
}
protected abstract void execute( ScreenActionContext screenActionContext );
protected abstract boolean isValidSelection( ScreenActionContext screenActionContext );
protected abstract String getDisplay();
protected abstract String getTooltip();
protected abstract String getImage();
}
@Name( "deleteEntityScreenAction" )
public class DeleteEntityScreenAction extends SingleItemScreenAction
{
@In
private Session referenceSession;
public void execute( ScreenActionContext screenActionContext )
{
// TODO
}
public boolean isValidSelection( ScreenActionContext screenActionContext )
{
return !screenActionContext.getSelection().isEmpty();
}
protected final String getDisplay()
{
return "Delete";
}
protected final String getTooltip()
{
return "Logically deletes the selected items";
}
protected final String getImage()
{
// TODO:
return null;
}
}
Without the final modifiers on the DeleteEntityScreenAction getXXX methods I get the above exception when they are called from SingleItemScreenAction.getScreenActionMetadata(). But obviously with the final modifier I get no interception/bijection etc.
Wondered if this is a known limitation in cglib or not.
Cheers.
Mike.
