Passing values between workflow tasks

Question

I have a problem with passing property values between tasks. For example, in a start task I have defined a property:

<type name="mcwm:submitStart">
        <parent>bpm:startTask</parent>
        <properties>
            <property name="mcwm:projectName">
                <title>Naziv projekta</title>
                <type>d:text</type>
                <mandatory>true</mandatory>
            </property>

In my share-config-custom.xml I show that property on the start page and that's ok.

...
<show id="mcwm:projectName"/>
...
<field id="mcwm:projectName" set="general" />
...

Now on my second form I want to show the same field with the value that has been entered in the start form. In the model I didn't specify again this property for the second task, I just wrote:

...
<type name="mcwm:preparationOfProjectCharter">
   <parent>bpm:workflowTask</parent>
</type>
...

And in the share-config-custom.xml, I copied the first form configuration for the second form with one little change in the force="true" attribute:

...
<show id="mcwm:projectName" force="true"/>
...
<field id="mcwm:projectName" set="general" />
...

Now the field is there in my second form, but the value that is entered on my first form isn't - do I have to do something else to accomplish that and pass property values between forms?

Yes, you need to do something extra. See the Workflowadministration Wiki.

You need to pass variables through the workflow-context, either via mapping as shown in the Wiki or through the context itself (at least for JBPM, and probably also for Activiti)
