Error of boundary event is lost when converting to xml at DeploymentBuilderImpl.class

[despoina-kaz]

Describe the bug
I try to deploy a bpmn model that has an error for an error boundary event but when I try to get file back the model doesn’t have the error anymore.
I tried with this file also:

flowable-engine/modules/flowable-app-rest/src/main/resources/reviewSalesLead.bpmn20.xml

Line 11 in 3cc4d5e

<error id="notEnoughInfoError" errorCode="not_enough_info" />

I deploy my file like this:

Deployment deployment = repositoryService.createDeployment() .addBpmnModel(resourceName, model) .deploy();

and I am retrieving it like this:

repositoryService.getProcessModel(processDefinitionId)

I’ve noticed that inside DeploymentBuilderImpl.class here:

public DeploymentBuilder addBpmnModel(String resourceName, BpmnModel bpmnModel) { BpmnXMLConverter bpmnXMLConverter = new BpmnXMLConverter(); String bpmn20Xml = new String(bpmnXMLConverter.convertToXML(bpmnModel), StandardCharsets.UTF_8); addString(resourceName, bpmn20Xml); return this; }

My error is present at bpmn model but it’s not present at bpmn20Xml string.

Expected behavior
Error should be present when retrieving bpmn model

Code
Deployment deployment = repositoryService.createDeployment() .addBpmnModel(resourceName, model) .deploy();

Additional context
Flowable version: 7.1.0
used within Spring Boot app

The problem lies in this method:

bpmnXMLConverter.convertToXML(bpmnModel)

It doesn’t keep the error map.
I’ve checked the code of this method and it has the following:

DefinitionsRootExport.writeRootElement(model, xtw, encoding);
CollaborationExport.writePools(model, xtw);
DataStoreExport.writeDataStores(model, xtw);
SignalAndMessageDefinitionExport.writeSignalsAndMessages(model, xtw);
EscalationDefinitionExport.writeEscalations(model, xtw);

And ErrorExport should be added too
