Dynamically add region at runtime

1-      Create a .jspx page based on your template as usual  and leave it blank until this time
2-      Create  all the bounded taskflows  that you wants and create the page fragments as usual.
3-      Create a java bean class called"DhamanJavaBean"
Package org.dhaman
import oracle.adf.controller.TaskFlowId;
public class DhamanJavaBean {
    private String taskFlowId = "/WEB-INF/emp-flow.xml#emp-flow";
    public DhamanJavaBean () {
        super();
    }
     public TaskFlowId getDynamicTaskFlowId() {
      return TaskFlowId.parse(taskFlowId);
  }
} 
At this moment the calss contains only one attribute " taskFlowId" and only one method " getDynamicTaskFlowId()"
1-      Double click the "adfc-conf.xml" unbound taskflow and click on overview tab to add a new managed ben as follow:
-          Name:          dhamaBean
-          Class :          org.dhaman .DhamanJavaBean
-          Scope:          pageflow

2-      Now return to the  ".jspx" page and click on "Bindins" tab at the button of the page to open the  page definition bindings page.
3-      Under executable click add and select "adf task flow bindings" and select "task flow"

1-      Click ok  - the dialog will appear
1-      Id: region   " or you can write any name you like"
2-      taskFlowId: #{pageFlowScope.dhamanBean.dynamicTaskFlowId}   " this is the the method in the managed bean that will return the taskflow Id"
3-      click ok and return to the source of the page " I mean the jsf source"
4-      add a region tag under the facetRef  like this

         
                     value="#{bindings.region.regionModel}"/>
          >




1-      save all
2-      go to DataBindings.cpx and click on it and go to the structure window
  
1-      you will  add a "definition factory" in the databindings structure by right click on the Databindings and select "insert inside databinding" and select definition factory.
2-      A new folder will be created as "definitionFactories"
3-      Right click on that folder and select "insert inside" and select factory

-          Namespace:    http://xmlns.oracle.com/adf/controller/binding
-          className:   oracle.adf.controller.internal.binding.TaskFlowBindingDefFactoryImpl

1-      save all
1-      for testing add a default value for the " taskFlowId" in the java class. The default value is the task flow file  name followed by "#" and taskflow id as show in the example
2-      now run the .jspx file

Another user has changed the row with primary key oracle.jbo.Key[12 ].

Try these solutions:  make sure that you check "refresh after insert" and refresh after update" for the primary key column in you entity object. in the application module tab Click the Properties tab and select jbo.locking.mode. Double click the “pessimistic”value next to the property to open the field editor and type “optimistic” over the value.Press enter. if error still exist then you must set "refresh after insert" and refresh after update" as true for all attributes in the entity object another way is to execute the View Object after the commit operation to bring back updated data to ViewObject. For this we need to override the  afterCommit()  of ViewObject class as follows:                  public void afterCommit(TransactionEvent){                         executeQuery();                       }              5- another way to solve this error is to overide the lock() method of the EntityImpl class       public void lock() {

Working With File Throgh WebUtill

-------------------------------------------------- Required Configuraion : By default the file transfer is disabled in webutil for a security measure. So, you have to enable File transfer configuration in webutil.cfg file. The webutil.cfg file is located in  forms\server. Open The webuil.cfg file and edit the following parameters : transfer.database.enabled=FALSE   Change To TRUE transfer.appsrv.enabled=FALSE       Change to TRUE WebUtil_File contains APIs to manipulate files and directories on the client. These Functions Or APIs are: Copy_File :  Copies a file Returns a Boolean to indicate success.  Syntax :   Webutil_File.Copy_File(SourceFileName in Varchar2 , Destination In Varchar2) Return Boolean  Example   Declare  vCopied Boolean;  Begin   vCopied :=  Webutil_File.Copy_File('C:\temp\mypic.jpg','X:\destination_folder');  If vCopied = true Then    Message('File copied Successfully');  Else   Message('Error in Copying File');  End if; Delete_File:
