Although I consider myself a rather experienced JSF developer I still occasionally hit a strange bit of functionality which hit me as unexpected. Can anyone tell me if the following test case is expected behavior and if it is expected why is it? (FYI The test below functions the same in MyFaces and the JSF-RI so I imagine it is a spec question)
Given the following test case: ------------test.jsp------------- <%@ taglib uri="http://java.sun.com/jsf/html"; prefix="h" %> <%@ taglib uri="http://java.sun.com/jsf/core"; prefix="f"%> <f:view> <h:form> <h:dataTable value="#{test.values}" var="value"> <h:column> <h:message for="item"/> <h:inputText id="item" required="true" /><br/> </h:column> </h:dataTable> <h:inputText id="item2" /><br/> <br/> <h:commandButton value="Submit Me"/> </h:form> </f:view> -------------------Test.java------------------- import java.util.ArrayList; import java.util.List; public class Test { public List getValues() { List values = new ArrayList(4); values.add(null); values.add(null); values.add(null); values.add(null); return values; } } Basically, if you populate all of the inputText boxes and press "Submit Me" then the top 4 forget their value but the bottom one does not. If you only populate a subset of the top 4 boxes (invoking an invalid state for the table) then all the fields are remembered. However, once all fields are populated the components in the table forget their state again when submitted. All the while the bottom inputText that resides outside the dataTable remembers its state the whole time. Can anyone tell me why the dataTable does not remember the state of its children always like all other components? Mike
