How to store complex objects? I have an object in my list of children objects in which the object contains four lists of child objects, when the calling messengerist (person) object is not saved. help !!!!!!!!!!!!

I am calling pm.makePersistent (); But lists

@ententent private list & lt; Select Element Antity & gt; ChoosedElements = New ArrayList & lt; Selected Element Antity & gt; (); @ Personal listing of presentation & lt; PleasantElementEntity & gt; Pleasant Elements = New Arrestists & lt; PleasantElementEntity & gt; (); @ Presentation Private List & amp ;;; Unpleasant Element Antity & gt; Offensive Elements = New Array List & Lt; Unpleasant Element Antity & gt; (); @ Presentation Private List & amp; Set; List; SetIevilment Entity & gt; SetViewElements = New ArrayLight & lt; SetViewElementEntity & gt; ();

Not saved!

Example:

  @PrivacyPabile (table = "person", identity type = identity type, exception.) Public category personality {@PrimaryKey @ Persistent (Manuscript = ID Generator. Trent. Indi) Private Long Id; @Pententant Private List & amp; Offerment & gt; Offer = New Arrestist & lt; OfferIntity & gt; (); } @ PRECISION CAPABABLE (Table = "Offer", Ident Type = Identity Type. Application) Public Class Offerment {@ Prerequisitor's Present (Val Strategy = ID Generator. Strategy). Private key ID; @ententant private list & lieutenant; Selected Element Antity & gt; ChoosedElements = New ArrayList & lt; Selected Element Antity & gt; (); @ Personal listing of presentation & lt; PleasantElementEntity & gt; Pleasant Elements = New Arrestists & lt; PleasantElementEntity & gt; (); @ Presentation Private List & amp ;;; Unpleasant Element Antity & gt; Offensive Elements = New Array List & Lt; Unpleasant Element Antity & gt; (); @ Presentation Private List & amp; Set; List; SetIevilment Entity & gt; SetViewElements = New ArrayLight & lt; SetViewElementEntity & gt; (); } @ Press Capsule (Table = "Offer_Subends", Identity Type = Identity Type, Authorization) Public Class Choice Element Entity {@ Primikey @ Persistent (Wellstatistics = ID Generator.trazage.INTTTI) Private ID; @ Presentation Private string code; @ Prestige Private Text Semi Commands; } @ Press Capsule (table = "offer_seb", type identification type = identity), public category, happy elementary entry {@ premikey @ persistent (value strategy = id generator credit) private key ID; @ Presentation Private string code; @ Prestige Private Text Semi Commands; } @ PresenceCapple (Table = "Offer_Subends", type identity = type identity) public class unpleasant element entity {@ premiere @ persistent (value strategy = id generator.Tradent.indenti) private key ID; @ Presentation Private string code; @ Prestige Private Text Semi Commands; }  

• You can declare all sections in the object hierarchy @pressCAPABABLE
• Have you declared the list / object according to the variable set? I.e.:

   @ element (dependent = "true") private set tag = new hashset ();   

• Did you makePersistentAll (person) ?
• , check that your data is actually
• are you shutting down your handkerchief? I.e. pm.close () . Unless you turn off the handler, the data never stays, i.e.:

   // All objects are manupliated using a pm object unrestricted manager pm = PMF.instance (). GetPersistenceManager (); // do work // change pm.close ()
