Who cares about Types? Querying with Numeric Variable Values
The final camunda 7.2 release is a stone’s throw away and ships a ton of new features. One of these is the typed variable value API. You may already know the plain-value-based API that exists since the process engine’s very first days. A variable can be set on an execution/task/… as follows: execution.setVariable(“var”, 42); Behind the scenes, the process engine performs some magic to squeeze numbers, booleans, or even complex Java objects into the database and return it from there on the next call: int myLuckyNumber = (Integer) execution.getVariable(“var”); With 7.2 (and the latest alpha), we introduce the typed value API. It is not a whole new API but rather of a gentle extension. Like before, the variable API is…

Job Suspension – Powerful Operations with Camunda BPM
This blogpost is about a very powerful feature in camunda BPM for operating critical processes which are in production. Given a core process which operates under high volume, almost any problem is critical in a way. The more options you have to deal with those problem the better. I am going to show you one of those options, namely job suspension. The Process Let’s say you have automated your order processing, i.e. the orders which are generated in your web shop. I will use a very simple example. New orders start a process in the backend, the delivery is scheduled and once the goods are delivered, the payment is scheduled. Let’s say your business is successful and you have…

Introducing Task Filters
With Camunda BPM 7.2.0-alpha5, we introduce Task Filters. Task filters are TaskQueries which can be saved to the database so that you can run them repeatedly. Creating a Filter using Java API At a Java API Level, a filter can be created as a regular task query: // create a taskQuery TaskQuery myTasksQuery = taskService.createTaskQuery().taskAssignee(“daniel.meyer”).active(); // save taskQuery as filter Filter myTasksFilter = filterService.newTaskFilter(“My Tasks”); myTasksFilter.setOwner(“daniel.meyer”); myTasksFilter.setQuery(myTasksQuery); String filterId = filterService.saveFilter(myTasksFilter); // execute the filter List<Task> tasks = filterService.listPage(filterId, 0, 20); If you want to share the filter with other users and for each user, make should return that particular user’s tasks, it is possible to use Expression Language in the task query: taskService.createTaskQuery().taskAssigneeExpression(“${ currentUser() }”).active(); The above example uses…

One of them begin a Task Listener.

camunda BPM Community Day 2014
Last Thursday we organized the 2nd camunda BPM community Day. After visiting Prague last year we went for the home game and invited the community to our Berlin offices. So we put all our desks and chairs and other stuff away to make room for the attendees. Around 65 people had registered and without doing an exact headcount, I suppose that more than 50 attended which Bernd described as “the biggest open source community day he ever attended”. Sandy Kemsley, who also attended, already published extensive summaries on the most of the talks so I am just going to link to them here: Australia Post at Camunda Community Day camunda Community Day technical presentations What’s Next In camunda – Wrapping…
