Hi everyone,  
I have a document declared in my pool, and i want to get this document in a subprocess of this pool.  
I tried some weird things to do this with groovy scripts, but not really successful.  
Someone can explain me how to do this ?

Cheers.

PS: I’m working on Bonita 6.2.5

Hi Fabien.  
The most simply way to achive your goal is the following:

1. add a document instance in the main process. let’s call it “mainDoc”
2. add a document instance in sub.process. let’s call it “subDoc”
3. in the call activity add a task Long variable (docId) that will contain mainDoc ID. add this code to store the value in the variable default value  
  
apiAccessor.getProcessAPI().getLastDocument(processInstanceId, “mainDoc”).getId();  
4. add a Long variable in sub-process. (sub\_docId)
5. map the docId with sub\_docId using mapping feature in call activity
6. add an automatic task as first task in sub\_process that will get the mainDoc, create a new DocumentValue and assign it to subDoc. Let me exaplaine more in details:  
add a new operation in the automatic task.  
  
import org.bonitasoft.engine.bpm.document.Document;  
import org.bonitasoft.engine.bpm.document.DocumentValue;

Document doc=apiAccessor.getProcessAPI().getDocument(sub\_docId);  
DocumentValue docValue=new DocumentValue(apiAccessor.getProcessAPI().getDocumentContent(doc.getContentStorageId()), doc.getContentMimeType(), doc.getContentFileName());  
return docValue;  
  
use “Set document” as kind of operation and assign it to subDoc.

That’s all.  
Let me know if it solve your problem.  
Ciao

Bonjour,

Je travaille sur Bonita 6.2.5 , n’étant pas encore très avancée dans mon projet.

En effet, je ne vois pas comment définir un sélecteur d’acteur, comme dans Bonita 5.10, et de même je n’arrive pas à créer des acteurs.

Quelqu’un peut-il m’aider?

Merci d’avance.

Pardon, j’ai pas trouvé “Assigned to data”, j’ai seulement “Associé à la variable” ou “Associé a l’input du contrat”.  
et est ce que je suis le même démarche pour le fichier ou quoi?  
En fait dans le fichier ci\_joint: [https://www.dropbox.com/home?preview=url-1.0.bos](https://www.dropbox.com/home?preview=url-1.0.bos) un simple exemple que j’ai développé, est il possible de montrer ce que je demande sur mon exemple? ou donner moi un exemple que je le suivre? Merci pour votre aide.

Hello, gentlemens

I don’t understand where I do the assignment. I followed the instructions and doesn’t worked.  
When I tried to assign the script to the SubDoc appeared the message that the variables are incompatible.

Best Regards  
Mario Borges

You can get the working example here: [https://github.com/Bonitasoft-Community/parent-child-shared-document/releases](https://github.com/Bonitasoft-Community/parent-child-shared-document/releases)

Note that in your case issue is that return type of the Groovy script expression is set to java.lang.String instead of org.bonitasoft.engine.bpm.document.DocumentValue

I shared a solution that is compatible with Bonita BPM 7.1.5.

I would highly recommend to upgrade from version 6 to version 7 in order to benefit from v7 new features.

Une URL peut être traitée comme une donnée de type texte.

Si cette information est stockée dans une business data les deux pool doivent déclarer une référence à la business data. Dans le mapping des données (configurer sur la call activity) il faut utiliser l’option “Assigned to Data”.

“Associé à la variable” est l’option à utiliser. Si cela ne fonctionne pas je pourrais étudier votre exemple.
