Unable to easily replace asynchronous dispatchers because of package-private methods
------------------------------------------------------------------------------------
Key: JBSEAM-4408
URL: https://jira.jboss.org/jira/browse/JBSEAM-4408
Project: Seam
Issue Type: Feature Request
Components: Async
Affects Versions: 2.2.0.GA, 2.2.0.CR1, 2.1.2.GA, 2.1.2.CR2, 2.1.2.CR1, 2.1.1.GA
Reporter: Reid Pinchback
One of the benefits of Seam is that you can install your open components to replace the built-in ones provided by Seam.
I was attempting to replace the ThreadPoolDispatcher, when I encountered something that maybe should change in the Schedule and TimerSchedule API. Instances of those classes can be created, but the values in them cannot be accessed because their accessors are package-private. For example:
public class Schedule implements Serializable {
private Long duration;
...
Long getDuration()
{
return duration;
}
...
}
Since the member variables are private, you can't create subclasses of Schedule or TimerSchedule to get at them, and because the accessors are package-private, you can't get at them that way. Similarly any subclass of AbstractDispatcher in a different package can't access those values for determining the appropriate values for scheduled futures.
The only work-arounds at present are pretty grungy - either creating a subclass of TimerSchedule that keeps shadow copies of the member variables, or placing the application-specific dispatcher code in a package whose name mimics the Seam package structure. Neither is a show-stopper, but not really a good solution for a framework that is intentionally attempting to make itself extensible.
I'd recommend making the Schedule and TimerSchedule accessors public.

EntityQuery can't be used in PAGE Scope
---------------------------------------
Key: JBSEAM-2514
URL: http://jira.jboss.com/jira/browse/JBSEAM-2514
Project: JBoss Seam
Issue Type: Feature Request
Components: Framework
Affects Versions: 2.0.0.GA
Environment: Seam 2.0.0.GA, JBoss AS 4.2.2.GA

The EntityHome is not able to operate in PAGE scope and the documentation says nothing about compatible scopes and framework classes.
It throws an exeption:

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2301) JBoss EL bug handling overloaded methods with varargs mixed in

JBoss EL bug handling overloaded methods with varargs mixed in
--------------------------------------------------------------
Key: JBSEAM-2301
URL: http://jira.jboss.com/jira/browse/JBSEAM-2301
Project: JBoss Seam
Issue Type: Bug
Components: EL
Affects Versions: 2.0.0.GA
Reporter: Matthew Lieder
Doing facesMessages.add("Message") from an EL expression doesn't work, complaining about the String class not being compatible with the FacesMessage class. The problem is caused by a combination of two things:
1. There are two FacesMessages.add(...) that can accept one parameter: add(FacesMessage facesMessage) and add(String messageTemplate, Object... params)
2. The FacesMessages.add(...) that accepts a String as the first parameter can optionally accept additional parameters through a vararg
If only one of those was the case, it'd work fine. However, having both at the same time triggers the error.
