Use the Business Process Choreographer Explorer Details component
to display the properties of tasks, work items, activities, process instances,
and process templates.
Steps for this task
- Add the Details component to the JavaServer
Pages (JSP) file.
Add the bpe:details tag to
the <h:form> tag. The bpe:details tag
must contain a model attribute. You can add properties to the Details component
with the bpe:property tag. If the Details component
does not contain any properties, all of the properties of the object are displayed.
The following example shows how to add a Details component
to display some of the properties for a task instance.
<h:form>
<bpe:details model="#{TaskInstanceDetails}">
<bpe:property name="displayName" />
<bpe:property name="owner" />
<bpe:property name="kind" />
<bpe:property name="state" />
<bpe:property name="escalated" />
<bpe:property name="suspended" />
<bpe:property name="originator" />
<bpe:property name="activationTime" />
<bpe:property name="expirationTime" />
</bpe:details>
</h:form>
The model attribute refers to a managed bean, TaskInstanceDetails.
The bean provides the properties of the Java™ object.
- Configure the managed bean referred to in the bpe:details tag.
For the Details component, this managed bean must
be an instance of the com.ibm.bpe.jsf.handler.BPCDetailsHandler class.
This handler class wraps a Java object and exposes its public properties
to the details component.
The following example shows
how to add the TaskInstanceDetails managed bean to the
configuration file.
<managed-bean>
<managed-bean-name>TaskInstanceDetails</managed-bean-name>
<managed-bean-class>com.ibm.bpe.jsf.handler.BPCDetailsHandler</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>type</property-name>
<value>com.ibm.task.clientmodel.bean.TaskInstanceBean</value>
</managed-property>
</managed-bean>
The example shows that the TaskInstanceDetails bean
has a configurable type property. The value of the type property
specifies the bean class (com.ibm.task.clientmodel.bean.TaskInstanceBean),
the properties of which are shown in the rows of the displayed details.
Result
Your JSF application now contains a JavaServer page that displays
the details of the specified object, for example, the details of a task instance.
