Hi Suoza,

There are many option how to implement it. Some of them:

extend types used by activiti-explorer form renderer (example: org.activiti.explorer.ui.form.UserFormPropertyRenderer).
use related content as a task attachment in the explorer

Hi,

extend types used by activiti-explorer form renderer (example: org.activiti.explorer.ui.form.UserFormPropertyRenderer).

This example is a part of activiti-explorer source code.
(detailed description could be found in the activiti in action (10.4 Custom form types and external form rendering)

(/WEB-INF/activiti-ui-context.xml)


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

(/WEB-INF/activiti-standalone-context.xml)


  <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
   <property name="dataSource" ref="dataSource" />
   <property name="transactionManager" ref="transactionManager" />
   <property name="databaseSchemaUpdate" value="true" />
   <property name="jobExecutorActivate" value="true" />
    <property name="customFormTypes">
      <list>
        <bean class="org.activiti.explorer.form.UserFormType"/>
        <bean class="org.activiti.explorer.form.ProcessDefinitionFormType"/> 
        <bean class="org.activiti.explorer.form.MonthFormType"/>   
      </list>
    </property>
  </bean>

It shows how custom form types could be added to the activiti-explorer.

use related content as a task attachment in the explorer

Click on the task in the activiti-explorer.
On the user task form is the section "Related content" click on the (+) button on the right.
You should be able do add link or file to the task.

Regards
Martin

I committed a fix for this which should be in the next release. The Matching strategy throws a NPE when trying to match/open an editor that's not a BPMN process.
