ICEfacesでbeforePhaseが動作しない？
JSF1.2から
Chapter 11 Using JavaServer Faces Technology in JSP Pages
Visual Webを使いたくない（使えない）場合に便利そうな機能だと思いましたが、ICEFacesと合わせると動かないんですよね。同じように悩んでいる人を発見するも、解決策を見つけることはできませんでした。
ICEfacesでbeforePhaseが動作しない？
試したコードはこんな感じです。
<f:view beforePhase="#{Page1.hoge}">
public void hoge(PhaseEvent pe){
}すると、以下のエラーが吐かれます。

GlassFishだとあまり情報がありませんが、Tomcatだともうちょっと情報があり、MethodのところにValueを突っ込んでるみたいなエラーが書かれています。
何となく、com.icesoft.faces.webapp.parser.ELSetPropertiesRule.beginがイヤな感じなので、中を見てみます。
public void begin(Attributes attributes) throws Exception {
FacesContext facesContext = FacesContext.getCurrentInstance();
HashMap values = new HashMap();
Object top = digester.peek();
for (int i = 0; i < attributes.getLength(); i++) {
String name = attributes.getLocalName(i);
if ("".equals(name)) {
name = attributes.getQName(i);
}
String value = attributes.getValue(i);
//take a guess at the types of the JSF 1.2 tag members
//we are probably better off doing this reflectively
if (name != null) {
values.put(name, value);
if (("id".equals(name)) ||
("name".equals(name)) ||
("var".equals(name))) {
values.put(name, value);
} else if (top instanceof UIComponentTag) {
//must be a JSF 1.1 tag
values.put(name, value);
} else if ("action".equals(name)) {
values.put(name,
getMethodExpression( facesContext, name, value,
null ));
} else if ("validator".equals(name)) {
values.put(name,
getMethodExpression( facesContext, name, value,
null ));
} else if ("actionListener".equals(name)) {
values.put(name,
getMethodExpression(facesContext, name, value,
ActionEvent.class));
} else if ("valueChangeListener".equals(name)) {
values.put(name,
getMethodExpression(facesContext, name, value,
ValueChangeEvent.class));
} else {
values.put(name,
getValueExpression(facesContext, name, value));
}
if (top instanceof javax.faces.webapp.UIComponentELTag) {
//special case for
//com.sun.faces.taglib.jsf_core.ParameterTag
//and potentially others
if ("name".equals(name)) {
values.put(name,
getValueExpression(facesContext, name, value));
} else if ("locale".equals(name)) {
values.put(name,
getValueExpression(facesContext, name, value));
}
} else {
//reflection based code as mentioned above. More likely
//to be correct, but performance may not be as good,
//so only applying it in a specific case
if ("name".equals(name)) {
Method setNameMethod = null;
try {
setNameMethod = top.getClass().getMethod("setName",
new Class[] { ValueExpression.class } );
} catch (Exception e) { }
if (null != setNameMethod) {
values.put(name,
getValueExpression(facesContext, name, value));
}
}
}
}
}
BeanUtils.populate(top, values);
}beforePhaseにはメソッドを指定するはずなのですが、このコードからはbeforePhaseの場合にはvalueが渡されているような雰囲気です。これが原因かどうかはもっと突っ込まないとわからないようです。ちょっと手に負えませんね。
beforePhaseを使えばすぐわかるような現象だとは思うのですが、使っている人が少ないのでしょうか？
