Internationalization in the Camunda BPM Tasklist

In an international open source project like ours, the users speak a huge variety of languages. When building our new Tasklist we had to address the question of how to deal with internationalization. Customizing Your Own Language In addition to the default language, we added the possibility to plugin your own language for all Tasklist texts, labels, dates and date formats. You can of course use multiple languages at a time, based on the browser settings of your users. To achieve this, you simply need to add your own language file(s) to your Tasklist, without even restarting the application. Read the documentation on how to customize your language settings. Existing Translations The great thing of having a community is that…

Cockpit and Deployments

The last days before I traveled to Hong Kong I built a cockpit plugin toshow and delete deployments. On my firstengagement, I thought about how to clean up my database from all thefailing process diagrams that I don’t need any more. I asked Bernd how toget rid of the old stuff. He deleted the H2 files from his computer.That’s a very fresh start. And he is now very fast in finding andinstalling the enterprise license key again. This could be done better in myopinion. On the next customer engagement Isaw a test system with version 168 of the process definition to test.Someone should clean up here. But how? Whatabout deleting the deployment with cascade=true? Who calls…

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…
