workflow issues

[kevin wu，修改在11 年前。]

Has anyone of you are familiar with Liferay workflow definition? I want to assign a task by user email ID, so I can do it like the following, but [e-mail] should be an input on UI page and then pass it to the workflow, how can I use a variable instead of [e-mail].

<task>
<name>Manager Approval</name>
<assignments>
<user>
<email-address>[e-mail]</email-address>
</user>
</assignments>
<transitions>
<transition>
<name>Reject</name>
<target>update</target>
<default>true</default>
</transition>
</transitions>
</task>
