        name="Ata"

    </extensionElements>

1. Extend the AbstractFormType class and override it's methods as shown in this example TextAreaFormType.java

2. Activiti Explorer is implemented in Vaadin so the form field also has to be implemented using Vaadin. Here you can find sample implementation

3. Add a custom form type to the process engine configuration in applicationContext.xml applicationContext.xml

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="customFormTypes">
<list>
<ref bean="userFormType"/>
<ref bean="textAreaFormType"/>
</list>
</property>
</bean>
<bean id="userFormType" class="org.activiti.explorer.form.UserFormType"/>
<bean id="textAreaFormType" class="org.bpmnwithactiviti.explorer.form.TextAreaFormType"/>
