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.
