Problem using dataTable, selectOneMenu and selectBooleanCheckbox together

[Shawn Recinto]

Hey guys, I running into an issue when using a dataTable (tomahawk or core) with selectOneMenu and selectBooleanCheckbox, for some reason its values are getting “defaulted” or “lost” i.e. on a selectOneMenu bound to a value object from a collection in the backing bean, where I have verified that the value is set correctly up until the point it started rendering the table, some render process sets the value to empty string, similar with the selectBooleanCheckbox except the value always gets set to false.  I purposely set the values to “true” in the UI and placed an exception for the check box for anything that set it to false and here is the sample stack trace I get.  This occurs on the rendering phase of the life cycle i.e. Response phase

threw when something from the component when through its processUpdates cycle.   Here is some sample code:   “from the JSF page” <t:dataTable id="centerInstanceList" var="centerForm"       value="#{ formBean.formInstances}"       styleClass="detailsGrid"       headerClass="detailsHeader"       rowClasses="detailsOnRow,detailsOffRow"       rowCountVar="rowCount"       rowIndexVar="rowIndex">       …       <t:column   style="width:10%"> <f:facet name="header"> <h:outputText value="#{messages.form_center_list_empDoc}" /> </f:facet>             <t:selectOneMenu value="#{centerForm.docuId}">                   <f:selectItems value="#{formBean.documentSelectItems}" />             </t:selectOneMenu>       </t:column>       …       <t:column   style="width:5%"> <f:facet name="header"> <h:outputText value="#{messages.form_center_list_Sta}" /> </f:facet> <t:selectBooleanCheckbox value="#{centerForm.accessable}"/> </t:column> </t:dataTable>     My FormInstanceVO is a pojo except for my debug exception code snippets (from backing bean formBean.formInstances)   public Boolean getAccessable() {                         return this.accessable;             }             public void setAccessable(Boolean accessable) {                         if(Boolean.FALSE.equals(accessable)) {                                     IESRuntimeException e = new IESRuntimeException("This should not be false");                                     e.printStackTrace();                                     throw e;                         }                         this.accessable = accessable;             }     An interesting thing to note is that if I change any of these it a <h:inputText /> or an <h:outputText /> it correctly display the values that are in the VOs   Could someone help me figure out what I am missing? Why would the dataTable override the values that were preset in the value objects for a selectBooleanCheckbox or selectOneMenu?   I am using MyFaces 1.3 Facelets 1.1.11 hibernate-3.2.0.cr2 Spring Framework 1.2.8   Running on apache-tomcat-5.5.17   TIA   Regards, Shawn Recinto
