Could not save the copied build engine using RTC java api

Dear Team,

I am trying to create a build engine in RTC by using java api. I use the method ".copyEngine()", but the new build engine is failed to save. The error message mentions that the item which I am trying to save could not be found from RTC database. 
Could you give me some advice?  
Thank you very much!

My code is simple as below:  


String originalBuildId = "CI_BF_Agent_NO.2";

IBuildEngine originalBuildEngine = (IBuildEngine) cbe.getBuildEngine(originalBuildId).getWorkingCopy();

//IBuildEngine newEngine = BuildItemFactory.createBuildEngine();

IBuildEngine  newEngine = originalBuildEngine.copyEngine(); 



newEngine.setProcessArea(originalBuildEngine.getProcessArea());, null);

I basically don't know. But you an search the RTC SDK for IBuildEngine, find the interface, and search for IBuildEngine.copyEngine() and look at what they are doing. If you run an Eclipse Debug client, you can actually step through the build engine creation wizard, which also uses the copyEngine() method.

 Dear Ralph,

Thank you very much for your information. I will try it later.

in my copy project utility, I was never able to make copyEngine() work either.. I gave up and wrote my own copy functions..

now, in MOST cases, I was trying to copy across systems, so the copyEngine() function wouldn't have worked anyhow.

please check

also all the comments. I believe the key might be to fetch the complete refreshed engine before copying:

buildEngine = (IBuildEngine) getTeamRepository().itemManager()
                .fetchCompleteItem(buildEngine, IItemManager.REFRESH, null);

If this helps please mark the answer as accepted,

 Dear Arne,

I tried the "fetchCompleteItem" method, but it still failed and reported the same error.
The error message is as below:
[main] INFO  [com.cbm.commons.SysoutProgressMonitor] - ConnectedException in thread "main" CRJAZ0215E Could not find the item blew from (stateId: <unset>, itemId: [UUID _e2tr8Cn2EeaDBeT3ten9bw], origin: null, immutable: <unset>)  at
