Monitor collaborating executable BPMN 2.0 processes in cockpit
In a current customer project we faced the issue that there were two executable processes – independent of each other. So far – so normal. But these two processes had to sync status here and there – so they were clearly related, but not by using a Call Activity. BPMN 2.0 allows this by communication via messages as shown in the following example. But how to keep track of this in monitoring? We developed a small cockpit plugin to show the related process instances – see below. The process is in the area of IT infrastructure management, where changes are handled by multiple different change processes handled by different departments which are pretty autonomous. But actually for today’s post it is not…

Create a camunda BPM Process Application using Maven Archetype in 1 minute
For quite some time we already use Maven Archetypes in our camunda BPM training and at customer projects to create camunda BPM Process Applications – which are normally simple Maven projects.I created a 30 seconds survey to get feedback on archetypes. We currently have two archetypes available: war: Use on Servlet containers like Tomcat. ejb: Use on EJB containers like JBoss AS, WebSphere, Glassfish or WebLogic. You can find the full documentation online: Maven Archetypes (Project Templates).So you can start using it today. Give us feedback! We currently discuss how important archetypes are for our community and what types of archetypes we should provide (if any). Please take 30 seconds to fill in our survey. Thank you!

Synchronous vs. Asynchronous Service Invocations – BPMN Service Task (1)
The BPMN 2.0 Specification provides the Service Task activity allowing users to invoke some application service. In this Blogpost I want to explain the difference between a synchronous and an asynchronous service invocation in Camunda BPM. NOTE: this blogpost covers the topic at an abstract level. If you are looking for concrete, ready-to-use examples, have a look at our quickstart repository: quickstart on synchronous service invocations quickstart on asynchronous service invocations Synchronous Service Invocations Let’s start with synchronous service invocations. A synchronous service invocation follows the well-known Request/ Response Pattern: The process engine performs a synchronous request to a service and waits for a response. The characteristic property of this invocation pattern consists in the fact that the process engine…

camunda Modeler 2.2.0 released: Kepler support and modeling improvements
Today we are happy to announce the new release of the camunda Modeler. This version adds official support for Eclipse Kepler. On top of that it ships with the ability to change the type of tasks, events and gateways as well as a simplified connection of elements. Eclipse Kepler Support Kepler support is finally there. Head over to the downloads site and get a fresh version of the modeler, ready for Kepler. Morphing áka Changing Flow Node Types Morphing flow nodes to different types is something we are pretty exited about because it makes it a lot easier to change existing process models. Thanks to Roman, this feature is now available via the actions menu as two small gears for…

How to send an email when a usertask is assigned
“I don’t want to watch my camunda Tasklist all day. When there is something to do, I want to get an email containing a link that takes me directly to the respective task!” This is a typical statement by process participants (aka business users). There are numerous possible ways to implement such a requirement in your process application, e.g. using a service task: But this is not really appropriate, since it makes the process model rather verbose and therefore less valuable for business-IT-alignment. The more elegant way is to use a task listener: This very powerful concept is described in detail in the userguide, and the behavior we want is a perfect use case, so let’s see how it works!…

camunda BPM: Power to Embedded Taskforms
For everyone out there using embedded task forms in the camunda Tasklist there is great news: The forms are getting way more powerful. The upcoming alpha of camunda 7.1 introduces two extensions for embedded task forms: Client side form validation and form extensions via JavaScript. Form Validation Validation directives provided by AngularJS may now be attached to form fields to activate simple client-side validation constraints for them. The following form field will only accept one of the strings demo, john, mary or peter due to the defined pattern: <input form-field type="string" name="assignee" ng-pattern="/^(demo|john|mary|peter)$<span id="goog_340102718"><span id="goog_340102719">/"</span></span> /> If a user enters an invalid value in a form field the field will be marked as invalid. Additionally the complete task button will be disabled and the form may…
