In the 7.1.0.M2 release you will find the following main fixes & features:

  • Added support for bpmn embedded sub-processes in the Activiti Modeling Application and Activiti Cloud

  • Process diagram available from query service -> GET /query/admin/v1/process-instances/{processInstanceId}/diagram

  • Variable type validation at modeling time (default value is validated against type).

  • Added support for PROCESS_DEPLOYED and SIGNAL_RECEIVED events in notification service

  • Removal of RabbitMQ binder

You can also deploy our Example HELM charts using your favorite cloud platform (i.e. AWS, GCP, Azure...) or on-premise Kubernetes installation by following our Getting Started Guide

Known issues / Changes from 7.0.x

RabbitMQ binder

RabbitMQ binder has been removed as dependency of Activiti Cloud Starters (activiti-cloud-starter-runtime-bundle, activiti-cloud-starter-query, activiti-cloud-starter-audit, activiti-cloud-starter-connector).

Now, you need to add the dependency to the binder of your choice along side with related Activiti Cloud Starter. For instance, if you choose RabbitMQ binder you should add:

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-stream-rabbit</artifactId>
</dependency>

This will solve the following exception that you may be experimenting after moving to 7.1.0.M2:

org.springframework.context.ApplicationContextException: Failed to start bean 'outputBindingLifecycle'; nested exception is java.lang.IllegalArgumentException: A default binder has been requested, but there is no binder available

Connector names

As the connector names can be used to create pods on kubernetes, these names need to be validated against DNS-1123 conventions. The regex used in the kubernetes UI itself is "a-z0-9?"

Variable mappings

In release 7.1.0.M2 variable mappings have been updated to use names instead of UUIDs:

Before 7.1.0.M2:

"mappings": {
"Task_1spvopd": {
"inputs": {
"movieNameUUID": {
"type": "variable",
"value": "movieToRankUUID"
}
},
"outputs": {
"movieDescUUID": {
"type": "variable",
"value": "movieDescriptionUUID"
}

From 7.1.0.M2:

"mappings": {
"Task_1spvopd": {
"inputs": {
"movieName": {
"type": "variable",
"value": "movieToRank"
}
},
"outputs": {
"movieDesc": {
"type": "variable",
"value": "movieDescription"
}
}
}
}

If you're using variable mappings you need to replace process variable and connector input/output UUIDs by the respectif names. You can find names of process variables inside the extension file and names for connector inputs/outputs inside the connector definition file.

Helm Charts refactoring

All chart archives are moved to https://github.com/Activiti/activiti-cloud-helm-charts Full chart located at https://github.com/Activiti/activiti-cloud-full-chart

Now full chart has flat structure - application and infrastructure sub charts are removed. Common chart is a base chart for all charts and it is located at https://github.com/Activiti/activiti-cloud-common-chart. Charts for components located at component folders like:

In addition, some of the paths to services has changed:
