Update an Entity in WD Application

Question

Hi All,
in my Web Dynpro Application I can create an entity in an existing entity service. I can do that with the following code:
AChangeDescriptionDB db = ChangeDescriptionDBServiceProxy.create();          
db.setProcessID(processID);
db.setTitle(actualTitle);
db.setType(wdContext.currentContextElement().getType() );
db.getAspect().sendChanges();
But how can I update or delete an entity?
Should be possible, but I dont found out a way?
Thanks in advance
Steve

Hi Steve,
Which code are you using? As far as I can understand from your reply, its
code  line 1:  <i>IAspect tempAspect = ChangeDescriptionDBServiceProxy.findUniqueKey(uniqueKey);</i>
  //This returns you only one record. So you do not use the iterator but directly get the first row as follows
code line 2:
<i>if(tempAspect!=null){
AChangeDescriptionDB db = (AChangeDescriptionDB) tempAspect.get(0);
}</i>
Can you please confirm if this code line 2 where you are typecasting is giving you the error? I am confused because you have mentioned 2 codes from 2 different scenarios, itr.next() for list and .getAspectRow(0) for single record. Or is it like both these cases throw error when you use them separately?
Here I have to mention that you must have added public part default of DC tc/col/api (compartment
SAP_JTECHS) in order to use the code for "IAspect".
Please let me know the error. Also, please mention the version of NW2004s that you are using.
