Override constraints of bpm model

sversh71

Hello!

We have out of the box model "bpm:businessprocessmodel" and some constraints inside it.

        <constraint name="bpm:allowedStatus" type="LIST">
            <parameter name="allowedValues">
                <!–  TODO: Determine if status values can be mapped to human-readable strings –>
                <list>
                    <value>Not Yet Started</value>
                    <value>In Progress</value>
                    <value>On Hold</value>
                    <value>Cancelled</value>
                    <value>Completed</value>
                </list>
            </parameter>
        </constraint>

I'm working on solution for non english speaking users, so does anybody know how to override this constraint with localized values?
I know that it isn't possible to localize constraints with .properties file. So I need at least rewrite built-in values with my own.
Any ideas?

Solved.
If someone interesting I can explain

I'm pretty sure this problem has been raised many times and that no (good) solution was found.
Sharing your solution would definitely help many future users.

Thx

I don't think that my solution is good. It is suitable only for single language environment. I used the standard way to overwrite out of the box model with custom model.
In this case I do the following:
1. create context file or use an existing and copy there dictionaryBootstrap bean description from core-services-context.xml
Replace link to standard bpmModel.xml with custom bpmModel.xml

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>

    <!– Overwrite the existing models –>
    <bean id="dictionaryBootstrap" parent="dictionaryModelBootstrap" depends-on="resourceBundles">
        <property name="models">

2. Copy alfresco/model/bpmModel.xml to alfresco/extension/model/bpmModel.xml and change english language constraints values to localized.

        …….
        <constraint name="bpm:allowedStatus" type="LIST">
            <parameter name="allowedValues">
                <!–  TODO: Determine if status values can be mapped to human-readable strings –>
                <list>
                    <!– 
                    <value>Not Yet Started</value>
                    <value>In Progress</value>
                    <value>On Hold</value>
                    <value>Cancelled</value>
                    <value>Completed</value>
                     –>
                    <value>localized value 1</value>
                    <value>localized value 2</value>
                    <value>localized value 3</value>
                    <value>localized value 4</value>
                    <value>localized value 5</value>
                </list>
            </parameter>
        </constraint>
        …….
        <type name="bpm:task">
            <parent>cm:content</parent>
            <properties>
                ………..
                <property name="bpm:status">
                    <type>d:text</type>
                    <mandatory>true</mandatory>
                    <!– <default>Not Yet Started</default> –>
                    <default>localized value 1</default>
                    <constraints>
                        <constraint ref="bpm:allowedStatus" />
                    </constraints>
                </property>
            ……
            </properties>

That's all. If this solution has any potential weakness, please tell me

Tanks

jayjayecl

All Right, I did not understand it was suitable for only one language.

The potential weakness is when you'll want to upgrade your Alfresco platform.

I had to get to to the same result, and I prefered to create a new customStatus property in my workflowModel.xml instead of overriding the existing one.
