Problem in updating entity sevice record

Question

i am doing a POC for update through Web Dynpro
I have made an entity sergvice with a field as fname-short text- i create a record in it as  below and save its guid in a context varialbe
AFirstOne one = FirstOneServiceProxy.create();
one.setFname("hello");
one.getAspect().sendChanges();
wdContext.currentContextElement().setKey(one.getGuid());
Now i am trying to update the same record --
AFirstOne first = FirstOneServiceProxy.read
(wdContext.currentContextElement().getKey());
if (first ==null)
{  wdComponentAPI.getMessageManager().reportSuccess("null");
else
{  wdComponentAPI.getMessageManager().reportSuccess("not null");
wdComponentAPI.getMessageManager().reportSuccess(first.getGuid());
first.setFname("bye");
first.getAspect().sendChanges();
The not null and guid  is printed but the record is not updated  inn the table
Can anyone plaes suggest me the reason  for this?
What am i doing wrong ?

Hi
Data is Saved to database in two Steps.
Step 1 : call sendChanges() method on <entity>.getAspect()
Step 2 : call save method on ServiceFacade.
IServiceFacade  serviceFacade =
CAFServiceFactory.getServiceFacade(
<class Name>);
serviceFacade.save();
This will save the entty .
The Call to the "Save" Method  is missing in your Code.
