How to handle absent Assignees

“I want usertasks to be reassigned if the assignee is currently absent. How would I do this in Camunda?” As always, there is plenty of possible approaches to handle this situation. One of them begin a Task Listener. I created a little snippet that demonstrates how this can work: Absence Manager Snippet on GitHub For those of you who don’t want to build and deploy this demo application right away, there is also a little screencast below. How to handle absent Assignees from camunda on Vimeo.

cockpit plugin store

We have Camunda Cockpit as a great tool for monitoring and operations. But roles and requirements for monitoring and operations always differ in our real-life projects – so we allow plugins for Cockpit. In the last 48 hours (on our Camunda hackdays) we implemented a “plugin store” for the existing community plugins – so everybody can much easier try out plugins or see what plugins exist. The plugin store scans various GitHub repositories and searches for plugin metadata. And we compiled a list of all default plugins included in the standard distribution (as most of the cockpit functionality is implemented as plugin). You can browse through all plugins easily: Try it out: https://camunda.org/plugins/ After collecting plugins you can: download the cockpit.war: In…

The highlights of this release are: CMMN Listener support Embedded Forms in Tasklist JSON support in Spin JSON to Java mapping with Spin Simple REST HTTP Connector See complete release notes in Jira. Download camunda BPM 7.2.0-alpha4 now. Add Listeners to your CMMN Case Definitions As the CMMN support of our platform steadily increases we started to add features known from our BPMN implementation. With this alpha release you can add camunda:caseExecutionListener to plan items and camunda:taskListener to human tasks: Case execution listener can be added for the following state transitions: close, complete, create, disable, enable, exit, manualStart, occur, parentResume, parentSuspend, parentTerminate, reactivate, re-enable, resume, start, suspend and…

Hello ${name}! – Templating with camunda BPM

As part of our scripting improvements we also addressed templating as a new feature of camunda BPM. With the new camunda BPM 7.2.0-alpha3 release it is now also possible to use FreeMarker or Apache Velocity templates inside your BPMN process. We integrated this template engines as JSR 223 compatible scripting engines. Therefore we create small wrappers for these template engines in our camunda-template-engines-jsr223 project. This has the advantage that we do not need new extension elements or attributes for the BPMN xml. Instead a template can be used everywhere a script can be used. This is especially useful for script tasks and input output mappings. If the template engine JSR 223 wrapper is part of your classpath you can use the name of…

News from the front-(end)

The front-end of the Camunda BPM platform has been under heavy development.The web-apps have been externalized and separated into different projects,which means that the “admin“, the “cockpit” and the upcoming “Tasklist” have their own repositories,and those projects are now relying on the “UI commons” and the “JavaScript SDK” libraries. The JavaScript SDK The actual JS SDK has already been implemented in the upcoming Tasklist and allows us to start processes and use their embedded forms (when they use one). The forms handling is also being re-written from scratch to be easier to use and less conflicting with the HTML you might have wrote to customize your user experience. New embedded form: What did change? Mostly, the attributes. An embedded form must have…

Embedded Case Management with CMMN in camunda BPM

In our latest alpha release we include a preview of the upcoming support for CMMN (Case Management Model and Notation) in camunda BPM. Time to have a look at CMMN and the way it is implemented in camunda BPM. What is CMMN? CMMN is an emerging OMG standard for (Adaptive) Case Management. Version 1.0 is freshly released and vendor adoption starts to take off. Trisotech already provides a Web-based Modeler for CMMN and we at camunda have the ambition to provide the first embedded, Open Source Runtime Engine for CMMN. CMMN allows modeling Cases. A case allows humans to do work in a more or less structured way in order to achieve something. Classic examples where case management is applied…

Scripting Everywhere in camunda BPM

With the last camunda BPM 7.2.0-alpha3 release we heavily extended the scripting support of the camunda BPM platform. We started to improve scripting support with the 7.2.0-alpha1 release and now we think we are done. It is now your turn to start using the different scripting languages and help us to polish this feature for our final release. To get an detailed overview of the scripting support please visit our user guide. Where can I use scripts? Everywhere but to be more specific you can use scripts as: Script tasks (of course) Execution listener Task listener Condition of sequence flows Input output mapping (added in 7.2.0-alpha2) The implementation of the scripting support in camunda BPM is designed to be independent…

The Case for Open Source Embedded Case Management

In camunda BPM we enhance our lightweight embedded BPMN Process Engine with case management features based on CMMN. CMMN is the new emerging industry standard for (Adaptive) Case Management (ACM) developed by the OMG (Object Management Group), the same consortium which is also behind the BPMN 2.0 standard. I believe that lightweight open source solutions based on open standards can make a difference in the case management space. This is why. The traditional “hard-coded” Approach Traditionally, case management applications were hard coded. If an enterprise needed an application for handling credit applications, it would call on to their Java Developers (or worse: their Cobol Mainframe Developers), there would be some kind of software specification document written and the developers would…

Advanced Asynchronous Continuations in camunda BPM

Asynchronous continuations are a a very powerful process engine feature. Up until now you could use asynchronous continuations in two ways: Before an activity. Asynchronous process instantiation using the async start event. (Added in 7.0). With camunda BPM 7.2.0-alpha3, Asynchronous continuations become even more powerful: You can now place an asynchronous continuation AFTER an activity. (HOT!) Asynchronous continuations are now supported on more BPMN 2.0 constructs, such as the Parallel Gateway. Why Asynchronous Continuations? Asynchronous continuations are break-points in the process execution. They are used as transaction boundaries and allow another thread than the currently active thread to continue execution. From a use case perspective Async is used for placing a safe-point before an activity such that…
