Subject [jira] Created: (MYFACES-225) dataTable ArrayIndexOutOfBoundsException with input fields
Date Mon, 02 May 2005 08:30:21 GMT
dataTable ArrayIndexOutOfBoundsException with input fields
----------------------------------------------------------

         Key: MYFACES-225
         URL: http://issues.apache.org/jira/browse/MYFACES-225
     Project: MyFaces
        Type: Bug
 Environment: MyFaces-extentions 1.09, JSF RI 1.1_01, Tomcat 5.5.7, J2SDK 1.4.2_08
    Reporter: zpeedy


When I submit the form I get an ArrayIndexOutOfBoundsException. My guess the problem is that
the <x:inputText id="someInputText" required="true"/> doesn't render an unique Id.

== dataTable.jsp ==

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

<f:view>
<html>
<head>
</head>
<body>
  <h:form id="someForm">
    <x:dataTable id="someTable" var="item" value="#{applicationBean.someItems}">
      <h:column>
        <h:outputText id="someOutputText" value="#{item}" />
        <x:inputText id="someInputText" required="true"/>
        <h:message for="someInputText" />
      </h:column>
    </x:dataTable>
    <h:commandButton value="submit" action="#"/>
  </h:form>
</body>
</html>  
</f:view>

== ApplicationBean.java ==

public List getSomeItems()
{
    ArrayList list = new ArrayList(3);
    list.add("text1");
    list.add("text2");
    list.add("text3");
    return list;
}

== Exception stracktrace ==
