Unzip example_servicetask_1a.zip and example_servicetask_1a_support.zip respectively.

Build example_servicetask_1a_support.

cd example_servicetask_1a_support

mvn clean install

Build example_servicetask_1a.

cd example_servicetask_1a

mvn clean package // Build will succeed at this time because process1.bpmn is a file created using Business Central.

Open process1.bpmn using VSCode with BPMN Editor v0.25.0.

cd example_servicetask_1a

code src/main/resources/com/example/example_servicetask_1a/process1.bpmn

Once process1.bpmn file opened, save the file without modifying anything.

Build example_servicetask_1a again.

mvn clean package // Build will fail with the error (1) at this time.

Modify the 2nd line of process1.bpmn (starting with <bpmn2:definitions> element) like below. ..... (*1-1)

mvn clean package // Build will fail with the error (2) in question this time.

Actual result

Build ends up with failures.

Expected result

Build finishes successfully without any failures.

Component: VSCode BPMN Editor extension

Error description

Using BPMN Editor VSCode extention (0.25.0) for designing/editing processes, when we create a (Java) Service Task by reference to our product documentation [1] using the BPMN Editor, the bpmn file for the process causes a specific parser error in maven build.

I created a reproducer for the same error as the user encountered, and attached it in this JIRA.
Also, for the steps to reproduce the error, please see (*1) below.
By following the steps, you can see 2 issues/errors below, and (2) is the error actually reported by the user.

Error (1)

[ERROR] Node Info: id: name:

java.lang.NullPointerException

Error (2)

(*1) Steps to reproduce

I created the following 2 projects by following the documentation [1]. On Business Central, these projects can be run normally:

example_servicetask_1a.zip
- This contains a bpmn file (process1.bpmn) created using Business Central process designer.
example_servicetask_1a_support.zip
- This contains a Java class which ServiceTask calls.

To reproduce the errors (1) and (2), please follow the steps in jira's "Steps to Reproduce" section.

(4) Differences between the processes (2) and (*3):

The issue causing error (1):

    - xmlns:xsi="[http://www.w3.org/2001/XMLSchema-instance]" xmlns="[http://www.omg.org/bpmn20]"

in Line (*2-1) was modified to:

xmlns:xsi="xsi"

in Line (*3-1).

The issue causing error (2):

Lines at (*2-2) were removed in (*3), and also lines at (*2-4) were removed in (*3).

Possible root cause and notes

You can see the error (1) first after saving the bpmn file using BPMN Editor.
I think (1) is the issue reported in KOGITO-5714 Stunner - every process shows error messages during compilation.

We can avoid the error (1) by modifying the bpmn file like (*1-1), but every time we save the bpmn file, we need to modify it manually.

After avoiding the error (1) by modifying like (*1-1) manually, then you can see the error (2) in question.
Regarding (2), it looks for me like that inMessageRef and outMessageRef in bpmn2:operation are actually not used in (Java) Service Task. As far as I look at (*2), (*3), (*4), in BC process designer, however, both inMessageRef and outMessageRef remain in bpmn2:operation as dummy data so as to conform to the BPMN specification (inMessageRef must exist in bpmn2:operation). On the other hand, in BPMN Editor VSCode extension, neither inMessageRef nor outMessageRef are added in bpmn2:operation, so I am suspecting that the issue (2) is a bug in BPMN Editor VSCode extension.

Acceptance criteria

It is possible to successfully build the attached projects without failures.
