Can anybody suggest
where I have made mistake? My application
uses own PropertyResolver. It gets values for JSF components from XML documents
by XPath expressions, thus it can’t predict actual data type (String,
Integer, Boolean) of the returned value and always return some object with
implemented toString() method. This mechanism worked perfectly with Sun RI, but,
when I switch to MyFaces, it has failed. For some reason, MyFaces JSF
components need values of the certain data type (for example, Boolean for h:selectBooleanCheckbox).
Why it doesn’t try to convert value to expected type as suggested in JSP
2.0 spec? Where I have mistaken? ______ With Best
Regards, From:
Hello, I have two problems with
MyFaces 1.1.1. 1). I have created page: . . . . <h:selectBooleanCheckbox
id="checkbox" value="#{Bean.prop}"/> . . . . It is uses managed bean: public class Bean { public
String getProp() {
return "true"; } } During page rendering, MyJSF
throws exception: “java.lang.IllegalArgumentException: Expected submitted
value of type Boolean”. However, by specification (JSF 1.1 spec: Section
5.1.3 and JSP 2.0 spec: Section 2.8.5), string "true" must be
converted to Boolean by Boolean.valueOf() method. 2). Page: . . . . <h:selectOneMenu
id="menu" value="#{Bean.prop}">
<f:selectItem itemValue="1" itemLabel="1"/>
<f:selectItem itemValue="2" itemLabel="2"/>
<f:selectItem itemValue="3" itemLabel="3"/> </h:selectOneMenu> . . . . This time following beans
used: public class Bean {
public Prop getProp() {
return new Prop();
} } public class Prop {
public String toString() {
return "2";
} } Page rendering fails with
exception: “java.lang.IllegalArgumentException: Value is no String and
component form_id:menu does not have a Converter”. By specification (JSF
1.1 spec: Section 5.1.3 and JSP 2.0 spec: Section 2.8.2), Prop object must be
converted to String by Prop.toString() method. With Sun JSF RI both these
examples works properly. Is this MyJSF bugs or I have made something wrong? ______ With Best Regards, |
