Object expression getting coerced to String incorrectly

[glassfishrobot]

I'll attach the test war, but here are the details. Consider this page:

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

Where the bean and getter are like this: package com.sun.faces.component; import javax.faces.application.Application; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; import javax.faces.component.UICommand; import javax.faces.context.FacesContext; @ManagedBean(name="viewScopedBean") @ViewScoped public class ViewScopedComponentBindingBean { private UICommand button = null; public UICommand getCommandButton () { if (null == button) { FacesContext context = FacesContext.getCurrentInstance(); Application app = context.getApplication(); button = (UICommand) app.createComponent(context, "javax.faces.Command", "javax.faces.Button"); } return button; } } For some reason, the button is getting coerced into a String in AstCompositeExpression.getValue(): public Object getValue(EvaluationContext ctx) throws ELException { StringBuffer sb = new StringBuffer(16); Object obj = null; if (this.children != null) { for (int i = 0; i < this.children.length; i++) { obj = this.children[i].getValue(ctx); if (obj != null) { sb.append(obj); } } } return sb.toString(); } } I don't even know why AstCompositeExpression is getting into the picture, the expression does not appear to be a composite expression.
