Install BPM via IntelliJ's market place issue

chatnattaphon.r · May 2, 2025, 4:35am

Hello,

I’m currently developing an application using the Jmix Framework in IntelliJ IDEA. I have registered for a Trial Enterprise License via https://my.jmix.io, and so far I’ve been able to create projects and follow tutorials without any issues.

However, when I try to install the BPM (Business Process Management) add-on through the Jmix Marketplace in IntelliJ, I encounter an error during the installation process. Here’s what I did:

Opened the Jmix Marketplace in IntelliJ
Selected the BPM add-on and clicked “Install”
Entered my email and password used on my.jmix.io
Copied the license key from my profile page and pasted it into the prompt

Then I received the following error:

Installation Error: License key is invalid, or requested add-on is not included into the license.

I have double-checked that my license is an Enterprise Trial and it is still valid.

My Questions:

What could be the cause of this issue?
How can I resolve it?
Is the BPM add-on not included in the Trial license, or does it require additional activation?

If I need to contact the support team directly, what is the proper channel and what additional information should I provide?

Thank you in advance for your help!

Hi Chatnattaphon,

Thank you for evaluating Jmix!

The BPM add-on, as well as the other commercial add-ons, are not available through the Jmix Marketplace if you don’t have a valid Enterprise license.

To evaluate the add-ons, please request the Enterprise Trial on the https://store.jmix.io/account page and download a sample project that includes all commercial add-ons as described here: Account, Billing, and Subscription Management :: Jmix Documentation

You will be able to test the add-ons while working in the sample project, or copy the provided file-based repository with add-on artifacts from the downloaded sample project to your own test project.

Please let us know if you need further assistance.

Regards,
Konstantin

Thank you for your response.

I have now downloaded the BPM add-ons project and followed the steps in this video: https://www.youtube.com/watch?v=6IOLG8E7ueI&t=125s.

However, when I reach the step where I log in as Alice and click Start Process, I encounter the following error:

PropertyNotFoundException: Cannot resolve identifier 'workspaceRequest'

I would appreciate any guidance on how to fix this issue.
Our company is currently exploring potential software platforms that could support and enhance our internal system development. We see strong potential in Jmix and are evaluating its BPM capabilities as part of our consideration.

Hi Chatnattaphon, thanks for you interest in Jmix BPM!
First of all, I prolonged your trial license for 1 month.
Second, The PropertyNotFoundException: Cannot resolve identifier 'workspaceRequest' error typically occurs when a property or variable used in a BPMN process or a related script cannot be found or resolved.
Ensure that the workspaceRequest variable is correctly defined and initialized in your BPMN process. This variable should be set as a process variable before it is used in any expressions or scripts.

we will assist you additionally starting Monday.

Hi Chatnattaphon,

Please provide the full stack trace of the error (you can find it if you click the Details button).

In general, I would recommend to start experimenting with the BPM add-on in the demo project which is downloaded when you request the Enterprise trial: GitHub - jmix-framework/jmix-commercial-addons-demo-2: Jmix Commercial Add-ons Demo · GitHub. It includes the business process similar to the one described in the video, and this process 100% works.

Regards,
Konstantin

Here are the details of the error I encountered:

org.flowable.common.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'workspaceRequest'
    at org.flowable.common.engine.impl.de.odysseus.el.tree.impl.ast.AstIdentifier.eval(AstIdentifier.java:97)
    ...
    at io.jmix.bpmflowui.view.inputdialogform.InputDialogStartProcessForm.startProcess(InputDialogStartProcessForm.java:68)

Question 1:

Is there any difference between the BPM project downloaded from GitHub and the one available via the Enterprise Trial download page?

Question 2:

I tried downloading the BPM project from GitHub, but I couldn’t run it. I received this message:

“It seems that your Jmix project import failed, and as a result, Jmix Studio is not available.”

Any suggestions or clarification would be greatly appreciated. Thank you!

krivopustov · May 13, 2025, 10:34am

There is no difference in semantics. But the archive downloaded from your Account page includes also the set of trial artifacts of the commercial add-ons. You can see them in the trial_repository folder.

The GitHub repository contains the source code of the same project, but it requires an active Enterprise subscription to work.

Please use the project downloaded from your Account page to evaluate the Jmix commercial add-ons. If you want to create your own project with the trial add-ons, take the trial_repository folder and configure build.gradle in your custom project the same way as in the downloaded one:

repositories {
    mavenCentral()
    maven {
        url 'https://global.repo.jmix.io/repository/public'
    }
    if (file('trial_repository').exists()) {
        maven {
            url "file://${project.projectDir}/trial_repository"
        }
    } else {
        maven {
            url = 'https://global.repo.jmix.io/repository/premium'
            credentials {
                username = rootProject['premiumRepoUser']
                password = rootProject['premiumRepoPass']
            }
        }
    }
}

Hello @chatnattaphon.r,

This error occurs when there is no process variable ‘workspaceRequest’.

The demo application on GitHub and the application that was made at the webinar are slightly different, at the webinar they showed a more simplified version.

In the first version, the required process variable is added in a special screen com.company.demo.view.workspacerequest.WorkspaceRequestDetailView when the process starts:

Code:

    private void startProcess(WorkspaceRequest workspaceRequest) {
        String businessKey = workspaceRequest.getDate().format(DateTimeFormatter.ISO_LOCAL_DATE) + " - "
                + workspaceRequest.getEmployee().getFirstName() + " "
                + workspaceRequest.getEmployee().getLastName();
        Map<String, Object> variables = ParamsMap.of(
                "date", workspaceRequest.getDate(),
                "employee", workspaceRequest.getEmployee(),
                "workspaceRequest", workspaceRequest);
        runtimeService.startProcessInstanceByKey("workspace-preparation", businessKey, variables);
        notifications.create("Process started")
                .withType(Notifications.Type.SUCCESS)
                .withPosition(Notification.Position.TOP_END)
                .show();
    }

And the webinar shows a simpler option using a standard screen with the following expression:

Since the GitHub project has a variable called “workspaceRequest”, the following expression is used

<conditionExpression xsi:type="tFormalExpression">${workspaceRequest.workType.name() == 'OFFICE'}</conditionExpression>

Try replacing ${workspaceRequest.workType.name() == 'OFFICE'} with ${workType.name() == 'OFFICE'}

Regards,
Nikita

I’ve tried modifying the code in both process-drafts and process , and then restarted the application, but I’m still encountering the same error.

Could you attach your project here?
You can zip it using Zip Project command.

chatnattaphon.r · May 19, 2025, 8:34am

Here is my code. I can’t upload through this blog because of the size. so I was uploaded to the google drive. — I’d be grateful for your assistance.

chatnattaphon.r · June 16, 2025, 1:59am

Just following up — has there been any progress on the issue we discussed? @krivopustov

shchienko · June 16, 2025, 12:58pm

Hello @chatnattaphon.r,

I ran your test project, everything is correct in the source files.

Your project has several processes, one of which was deployed from Studio without errors and works correctly.

The second one has a problem, it was probably made in the Runtime Modeler.

You can remove unnecessary processes from Runtime Modeler and restart the application to ensure correct operation.

PS: Your trial version of the project has expired, you can get a new one in your personal account

Regards,
Nikita
