I have two association defined in aspect in my custom workflow model:

<aspect name="hxwf:multiassignaspect">
<associations>
<association name="hxwf:firstassignee">
<title>first assignee</title>
<source>
<mandatory>false</mandatory>
<many>false</many>
</source>
<target>
<class>cmerson</class>
<mandatory>true</mandatory>
<many>false</many>
</target>
</association>
<association name="hxwf:secondassignee">
<title>second assignee</title>
<source>
<mandatory>false</mandatory>
<many>false</many>
</source>
<target>
<class>cmerson</class>
<mandatory>true</mandatory>
<many>false</many>
</target>
</association>
</associations>

</aspect>

<sequenceFlow id="flow3" sourceRef="usertask2" targetRef="endevent1"></sequenceFlow>
<sequenceFlow id="flow4" sourceRef="startevent1" targetRef="usertask1"></sequenceFlow>
</process>

But the workflow haven't started and giving me the error as '' 

Unknown property used in expression: ${hxwf_firstassignee.properties.userName}

I need to assign the task to first assignee when initiator starts workflow , then it goes to second assignee. Please help me to achieve that. Thanks in advance

You can try using a task listener, attached to the complete event, and then in the javascript code, do something like:

execution.setVariable('firstassignee', task.getVariable('hxwf_firstassignee'));
execution.setVariable('secondassignee', task.getVariable('hxwf_secondassignee'));‍‍

Then, on the next task, you can have the variables firstassignee and secondassignee being used as expressions on the assignee property, like ${firstassignee.properties.userName} and ${secondassignee.properties.userName}
