Re: Re[2]: Child context for Web App

Hi again, Pierre! I think i finally understood your problem, forget all i said about nested contexts :) PG> It seems to me that if you want to make relations between objects, they have to be in the same context. Not 100% sure, but i think so. For workaround, you need that localObject() method.

Re[2]: Child context for Web App

Hi Pierre, I haven't actually ever used the 'localObject' method. I mean you can work with nested context the same way as with parent (global) one, i.e: DataContext context = DataContext.createDataContext(); DataContext nested = context.createChildDataContext(); Dicrow d = (Dicrow)nested.newObj

Re: Child context for Web App

Hi Pierre! When you use nested contexts (http://cayenne.apache.org/doc/nested-datacontexts.html), you don't need to manually copy objects between contexts, it collapses to just calling one method. I think that's exactly what you need. Manually calling setObjectContext (and even worse, deprecat

ROP & lifecycle

Hello! I'm using ROP and i want every client to be notified every time persistent object is stored. I know Lifecycle listeners aren't avaliable via ROP, but i need some way to implement this. This may not actually be linked with Cayenne, maybe you could advice any technologies. Any hint would b

Where can i download modeler source code?

If it's unavaliable on web, can someone please email it to me?)

Expressions & objects state

Hi all, these are actually two separate questions. First is about expressions. Suppose i have two entities, A and B. A has pk 'aid' and fk (non-mandatory) 'bid'. B has pk 'bid'. I want to build two separate expressions for A like those (1) 'aid=1' and (2) 'bid=2'. Since 'aid' and 'bid' are not

Re: State of DataObjects (uncommitted but nonexistent on DB)

Hi Adrian, If i understood your message right, you're manually changing objects' state to COMMITED. Well, i too think this is not a good idea. What would i do in this cause is to make those still non-existing in DB objects using default constructor, so that they would bу TRANSIENT. After that (i

Re[3]: ROP: validation and callbacks

I've found the answer: it turns out that client 'ObjAttribute' descendant, 'ClientObjAttribute' needed validation information. I think it is a good idea to make those 'isMandatory' and 'getMaxLength' methods members of 'ObjAttribute' so that the same validation code would work on client and serv

Re[2]: ROP: validation and callbacks

AA> Answering one of the questions, this is correct - there is no AA> callbacks available on the client. AA> Andrus Understood. About my first question.. I tried to invoke manually validation (forSave) from CayenneDataObject to my client PersistentObject (i.e. to copy-paste the code). Still t

ROP: DataObjectUtils.objectForPK() doesn't work
