Reading adf-config.xml entires...

If you want to read the adf-config.xml entries from Java code, try getting ADFConfig object from ADFContext and read the map of entries by passing specific name spaces. An example is copied below-
ADFContext aDFContext = ADFContext.getCurrent(); ADFConfig adfConfig= aDFContext.getADFConfig(); Map map= adfConfig.getConfigObject(""); Long rowLimit=(Long)map.get("jbo.row.limit");

An example for af:treeTable with af:inputComboboxListOfValues

Copying simple example for af:treeTable whose child column displays af:inputComboboxListOfValues component
<af:treeTable value="#{bindings.DepartmentsView2.treeModel}" var="node" selectionListener="#{bindings.DepartmentsView2.treeModel.makeCurrent}" rowSelection="single" id="tt1"> <f:facet name="nodeStamp"> <af:column id="c1"> <af:outputText value="#{node}" id="ot1"/> </af:column> </f:facet> <f:facet name="pathStamp"> <af:outputText value="#{node}" id="ot2"/> </f:facet> <af:column headerText="Manager ID" id="c10"> <af:inputComboboxListOfValues rendered="#{not empty node.EmployeeId}" id="managerIdId" …

Validating The Entity Collection When You Commit the Transaction

An example is shown below: /** * Validation method for Departments. */ public boolean validateDepartments(ArrayList ctxList) { Iterator iter = ctxList.iterator(); while (iter.hasNext()) { JboValidatorContext entValContext = (JboValidatorContext); DepartmentsImpl deptEO = (DepartmentsImpl)entValContext.getSource(); if (deptEO.getDepartmentName() == null) { // if Dept is null, throw error- this is just an example to illustrate the usage of this method return false; } } …
