Activiti Explorer & upload/download Attachement

Is it possible to create a bpm file to represent a process in which we can upload/download attachment in Activiti Explorer?
For example, in my bpm file, I have:

<activiti:formProperty id="textField" name="Input"   type="string" />
Activiti Explorer will display the above tag as a text field in the form for user to input.

How can I make Activiti Explorer let users upload/download attachment by modifying my bpm file?

Thank you,

Tan

You can add custom form-types to the explorer and the activiti-engine. This allows you to create any kind of control you want to display/fill in form-properties. Look in the codebase at UserFormType and org.activiti.explorer.ui.form.UserFormPropertyRenderer for an example. This call all be plugged in in the engine configuration (activiti-standalone-context.xml):

<br><bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration"><br>&nbsp;&nbsp; <property name="dataSource" ref="dataSource" /><br>&nbsp;&nbsp; <property name="transactionManager" ref="transactionManager" /><br>&nbsp;&nbsp; <property name="databaseSchemaUpdate" value="true" /><br>&nbsp;&nbsp; <property name="jobExecutorActivate" value="true" /><br>&nbsp;&nbsp;&nbsp; <property name="customFormTypes"><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <list><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.form.UserFormType"/><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.form.ProcessDefinitionFormType"/>&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </list><br>&nbsp;&nbsp;&nbsp; </property><br>&nbsp; </bean><br>
and explorer configuration (activiti-ui-context.xml):

<br> <!&ndash; Custom form property renderers can be plugged in here &ndash;><br>&nbsp; <bean id="formPropertyRendererManager" class="org.activiti.explorer.ui.form.FormPropertyRendererManager" lazy-init="true"><br>&nbsp;&nbsp;&nbsp; <!&ndash; Default renderer &ndash;><br>&nbsp;&nbsp;&nbsp; <property name="noTypePropertyRenderer"><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.ui.form.StringFormPropertyRenderer" /><br>&nbsp;&nbsp;&nbsp; </property><br>&nbsp;&nbsp;&nbsp; <!&ndash; Renderers by property type &ndash;><br>&nbsp;&nbsp;&nbsp; <property name="propertyRenderers"><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <list><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.ui.form.StringFormPropertyRenderer" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.ui.form.EnumFormPropertyRenderer" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.ui.form.LongFormPropertyRenderer" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.ui.form.DateFormPropertyRenderer" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.ui.form.UserFormPropertyRenderer" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.ui.form.BooleanFormPropertyRenderer" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bean class="org.activiti.explorer.ui.form.ProcessDefinitionFormPropertyRenderer" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </list><br>&nbsp;&nbsp;&nbsp; </property><br>&nbsp; </bean><br>
