camunda BPM 7.0-alpha7 released
camunda BPM 7.0.0-alpha7 is out now! The highlights of this new release are: In Cockpit we worked on the visualization of Process Instances: Incidents of a running process instance will be shown in the corresponding rendered process diagram. The former introduced Activity Instance Tree will be visualized as a tree. Now it is possible to select a BPMN element in the rendered process diagram or to select a activity instance within the activity instance tree. If a single BPMN Element is selected, the corresponding activity instances will also be selected in the tree (and vice versa). Variable instances of the process instance/activity instances will be shown in the view. In Cockpit you can switch between the configured process engines (multi-tenancy)….

Introducing an Activity Instance Model to the core Process Engine
(this post was originally part of the 7.0.0-alpha6 release blog post but later extracted into an own post). In 7.0.0-alpha6 we introduced the concept of activity instances and the activity instance tree to the core process engine. This post explains the motivation and gives some insight into the internal implementation. Why do we need an Activity Instance Tree? The activity instance tree contains a node for each activity that is currently active in the process instance. Some activity instances are scopes (such as Embedded Sub processes). Such scope activity instance may have child activity instances: So far so good. But is that not the execution tree provided by the process engine? To some extent yes, but not in all cases. There are…

PHP SDK for camunda BPM: new Incubation Project started
If you want to do BPM / Workflow and BPMN 2.0 in PHP then we have good news for you: as part of our camunda BPM polyglot initiative we started a new incubation project which aims at providing a PHP SDK for camunda BPM. This SDK will facilitate the development of PHP-based applications that use the camunda BPM middleware services. The project will provide a client library which authenticates against the REST Api and provide PHP developers with a native API for interacting with the process engine: While the camunda BPM project stays focused on Java as primary programming language, we believe that it is important to support developers that use other programming languages and give them access to the BPMN 2.0…

Extending Camunda Cockpit through Plugins
As we have seen in the past, it is impossible for Camunda Cockpit —our process monitoring tool— to satisfy all needs, out of the box. That is why we have long thought about providing it with an appropriate extension mechanism that empowers users to fit the tool to their very own monitoring needs. With the latest release of Camunda BPM a first version of a plugin system for Camunda Cockpit is finally here. So what is it about? Simply spoken it is about extending the cockpit GUI with custom views on everything that runs with Camunda BPM. Processes, process instances, deployments, tasks… you name it. That may be accomplished by providing backend services that execute custom queries against an engine…

Release early and release often. Today we bring you the next release of camunda BPM (7.0.0-alpha4). The Highlights are: First cut of new plugin API for camunda cockpit. Added message correlation to REST API. Support for shared process engine in IBM Websphere distribution (enterprise customers only). Read the full release notes in Jira. Message correlation in REST API With the previous release we added a message correlation method to the Java API. With this release we bring the new functionality to the REST API. (Read the docs). The API is pretty straight forward, just execute a POST to the /messageresource. Example: {"messageName" : "aMessage", "businessKey" : "aBusinessKey", "correlationKeys" : { "aVariable" : "aValue" }, "processVariables" : { "aVariable" : "aNewValue", "anotherVariable"…
