Retrieving the contextual variable processInstanceId and parentProcessId from the UI.

Q&A
1

Hi everyone,
I’m currently trying to retrieve a business data object keyed by the processInstanceId via a filtered query. Unfortunately, I can’t figure how to  access the processInstanceId or the parentProcessId from the UI. 

Any thought

Thx
david

Hi David,

If your UI is a Task form you may use /API/bpm/userTask/:userTaskId and retrieve the rootCaseId and parentCaseId attributes (Documentation reference).

Good question.

I make it a point to create a separate column in database to store the Process Instance Id manually.

Have you tried the below API

../API/bdm/businessData/com.company.model.Table?q=find&p=0&c=100

thx Dibyajit,

I did too store the process Id , and it seems to retrieve the associated one , but it's a little bit magic.

Using the API is difficult , because i need to filter it . I try to do it , by storing the processInstanceId in a process's variable, trying to retrieve it via ../API/bpm/caseVariable?processId inspired by an example  fund under https://github.com/Bonitasoft-Community/process-variable-example/

You can write your own Custom JPQL inside the BDM queries. You can define the parameters and output.
By creating a JPQL , you can have your own filter conditions. JPQL can be accessed through REST API.

Saving the Process Instance Id in a Process variable is not good because then after the case is archived, you will lose access to process variable.

Below is another variation


../API/bdm/businessData/com.company.model.Table?q=findByPersistenceId&p=0&c=100&f=persistenceId={{persistenceId}}

If the case is still active , use the context variable to manage the data.
If the Case is archived , use the REST API to pull the Data.

thx again Dibyajit for your helpfull insights,

I got some difficulty getting the persistenceId  or storageId by looking at Rest Api Context | Bonitasoft Community without success.

I have to switch to another project  but hopefully will be back ASAP.

Thx All,

Perfect, I should have read the API more attentively angry

According to the advice , i can finally access to my entity , following is the screenshot of the variables inside the UI tool

Name         Value                                           Type

context      ../API/bpm/userTask/{{taskId}}/context          External API
entity       {{entityLink}}                                  External API
entityLink   return '../' + 
             $data.context.myAddressCondition_ref.link;      Javascript
storageId    return 
             $data.context.myAddressCondition_ref.storageId; Javascript
taskId       id                                              URL parameter

 

All the Best
