Hi all

There is many times that i saw similar public api from ivy then i could not distinguish between them, i believe some of my co-workers has the same feeling. In this post i need your help to make it more clear.

Does they return the same result?

1/ Application:


2/ ProcessModel


3/ ProcessModels


4/ ProcessModelVersion


There is some more but first i stop here :)

Thanks in advance

We can write some small test processes to check it right? :D

Yes and no. If you do not understand it, I think we have to update the java-doc...

Yes, thanks. Actually i can create test and check for myself but can't do fo everyone. They need a clear documentation. This post here for them. They dont need to ask around everytime they use it. :)

First we have to separate between configuration and runtime data:

  • Configuration data are in the system database stored data, like Applications, Cases, Tasks, Users, etc.
  • Runtime data are not persistent and exists only at runtime, like the requests or sessions.

All API calls on the Ivy-Bean returns either configuration or runtime data related to the current execution context. E.g. the current executing request or the task of the current execution process.

The following APIs return runtime objects:

The following APIs return configuration objects:

Further calls on a configuration object returns always further configuration objects:

Hope this information will help. Don't hesitate to ask further question as comment. I will update the answer.

hi @Flavio Sadeghi ♦♦

Yes, i have another question, as you said "Case/Task lives always in the PMV the Case was started in". so for example i have a project A then i deploy it to PMV 1, i create some cases/tasks on this version.

Then i change implementation of Project A (i keep all task elements, just implement some new java class, new api, new logic). Now i deploy project A to PMV 2 (new version) and make it Active and Released.

Question: What happen if i start cases/task of PMV1 from released PMV (version 2)? which classes will be loaded?

I have some small test and i saw the old task will run on released PMV (PMV2), is it correct?

Hello @trungdv

How do you start a case/task of PMV1 from PMV2? I would argue that the the case/task is started in PMV1 and that classes of PMV2 are not visible in PMV1, since this would lead to conflicts, because classes exist in both PMVs, at least the class of the process itself... (except you have some application-wide caching , which is not allowed in such use cases)

If it should be possible, I would classify this as an bug. Of course, I would be happy for the test projecte to verify the behaviour.

hi @Flavio Sadeghi ♦♦

thanks a lot.

I just realize that somehow is a problem of deployment wizard tool, when i use it to deploy, it always deploy latest version on PMV1 (even i select PMV2 as the target). that's why i see the new logic on old cases.

So when i try with Deploy button on each PMV, it work as you said. alt text I'm using version 6.3.0, don't know whether this is an issue or not.

hi @trungdv

The deployment wizard decides on the basis of the project version (IvyProject -> Definitions -> Deployment -> Project Version) if a new PMV has to be created or an already existing PMV can be used. And yes, there were some fixes since 6.3...

hi @Flavio Sadeghi ♦♦ Continuous with PMV, i have a case as below:

In my app, we store the task in two places, when creating task, for the main data model, we store in our persistence (BusinessReposiroty) and we take out the id from there then store to Ivy Task.

Q1: When user open task, we have that id then load business data from Repository. this case will work.i guess it will load with classLoader of pmv which the task belong to. is it correct?

Q2: for the case we have that id then load directly data model from repo(not start from task), it could be an issue? any way to avoid it?
