Introduction
This page describes how to manage behavior of the application Id the mechanism of loading the right case with the right application in Blueriq so that it is possible to:
...
Processes are made unique in Blueriq by a so called ApplicationId application ID. This Id ID is an aggregation of the branch version and the project name and the branch version. For example:
Code Block | ||
---|---|---|
| ||
export-TestProject:1.0-Trunk |
where export-TestProject
is the project name and 1.0-Trunk
is the branch version.
In this article we will use the notation a:1
in the schema of <name>:<version>
. This ID . This Id is used to make sure to always address the correct case from a case list or work list. The same behavior applies using to message events.
So having an a unique identity is a good thing, but it also limits the way of deploying models and expanding an application using more than one projectsproject.
Requirements
By controlling the application ID behavior we are able to fulfil the following requirements:

Functional guideline
New properties are added to influence the behavior of models that normally make use of the application Id. Blueriq run time responds to four settings on three levels.
Settings
Loading an application
A case that has to be started triggers the application(s) that is/are needed to be able to run. Note that this implies that if there are a large number of applications available, it can take some time to determine which application is relevant.
Without options
Without any options the name and version of a case will be matched against the list of all applications. When there is an exact match, that application will be picked.
Settings
No additional settings are set.
Example
Cases | Applications | Comments | |
---|---|---|---|
a:1 | → | d:1 | case a:1 will trigger:
|
b:1 | b:1 | ||
c:1 | a:1 |
Ignore Options
You can configure an application to ignore certain parts of the application ID. You do this to be able to show cases from different applications in one list, or to be able to deploy an application from different branches.
The following ignore options will influence the behavior of matching applications with an application ID.

name and version | |
project | Ignores the |
project name part of the |
application ID. This can be used when multiple projects on the same branch share the same process model. | only version | This setting was introduced in Blueriq 9.8.5. | |
version | Ignores the version part of the application Id. This can be used when models are deployed from different branches. | only name | Typically for deploying from hot fix branches and different deployment strategies. |
all | Ignores version and project name from the application Id. This can be used when there are pages that wants to collect information from different projects. | nothing | Typically used in a dashboard for DCM applications. |
Example
In the following example we use all different kinds of settings to illustrate what their effect is.
Cases | Applications | Ignore | Comments | |
---|---|---|---|---|
a:1 | → | d:2 | all | case a:1 will trigger:
note that application b:1 will not be triggered, because they don't match on name and on version. |
b:1 | b:1 | none | ||
c:1 | a:3 | version | ||
d:1 | e:1 | project |
Applying the options
The options can be applied on different levels, as well as different components. They are specified in the

Levels
Level | Description | Comment |

Server
Global | The settings apply |
Project
...
to all applications | Default for all applications | |
Project | The settings apply to a specific project | These settings override the global setting |
It is possible to mix these settings, so a global setting and project settings. If for a project a project setting is defined, that one applies, otherwise the global applies.
Components
Component | Description | Comment |
---|---|---|
Process engine | Controls which part of the application |
ID is ignored by the process engine when |
handling message events. |
Process list | Controls which part of the application |
ID is ignored when displaying cases |
and tasks in |
lists (AQ_CaseList, AQ_WorkList, AQ_Timeline). For backward compatibility, when process list settings are not configured, the process engine settings apply. | This component was introduced in Blueriq 9.8.5. |
The settings are part of the aquima.properties for Java, or are part of the .Net configuration.
Rules
Rules for process engine
When handling message events, the Process Engine of an application A uses the following rules to determine which part of the application Id should be ignored:
- check the
process engine
setting for application A; if not configured then... - check the global
process engine
setting; if not configured then... - use
none
as default
Rules for process list
...
- check the the
process list
setting setting for application A; if not configured then... - check the global global
process list
setting setting; if not configured then... - check the the
process engine
setting setting for application A; if not configured then... - check the global global
process engine
setting setting; if not configured then... - use use
none
as as default
When handling timers and message events, the Process Engine of an application A uses the following rules to determine which part of the application Id should be ignored:
- check the
process engine
setting for application A; if not configured then... - check the global
process engine
setting; if not configured then... - use
none
as default
Aquima.properties
Java Runtime configuration is done in aquima properties:
Warning
If there is a deployment from a different version which is missing models compared to the current application, there is a possibility functionality won't work anymore. So ignoring versions can complicate things. For example a work list shows all tasks within a case ignoring version. But a task definition has been deleted and is not deployed from a new version. The task is still part of the process database, so it will show up in the work list because the version is ignored. Starting the task from the list will result in an error, because it cannot find its model definition.
Configuration
The configuration for the Runtime is applied to

.NET configuration
To configure ignore process version globally, add the processengine.appid_ignore
and processlist.appid_ignore
parameters to the aquima section as below:
Code Block |
---|
<aquima>
<properties>
<!-- Optional property to override the default value for ignoring the process version -->
<property name="processengine.appid_ignore" value="none" />
<property name="processlist.appid_ignore" value="none" />
</properties>
</aquima> |
To configure ignore process version per application, specify the application name and ignore mode as below in the webapplication
section:
Code Block |
---|
<applicationSettings>
<application name = "studio-RepositoryName1-ProjectName1" processEngineIgnoreMode="project" processListIgnoreMode="project" />
<application name = "studio-RepositoryName2-ProjectName2" processEngineIgnoreMode="version" processListIgnoreMode="version" />
<application name = "studio-RepositoryName3-ProjectName3" processEngineIgnoreMode="all" processListIgnoreMode="all" />
</applicationSettings> |
Work list and case list
...
app-id-ignore-modes.studio-RepositoryName3-ProjectName3 = all |
Example
Below an overview is given of the interaction between the different components.
Throw message event
The default behavior for throwing a message event is that it is thrown to the version and project of the corresponding application Id. So if we have a solution which consists of multiple projects, a broadcasted message should be broadcasted within the solution. It is possible that model wise the process is modeled in one module which is a library and imported in multiple projects. With the new settings it is possible to get the required behavior.
Warning
If there is a deployment from a different version which is missing models compared to the current application, there is a possibility functionality won't work anymore. So ignoring versions can complicate things. For example a work list shows all tasks within a case ignoring version. But a task definition has been deleted and is not deployed from a new version. The task is still part of the process database, so it will show up in the work list because the version is ignored. Starting the task from the list will result in an error, because it cannot find its model definition.
