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.
