Http Unit and JSF Generated JavaScript

Question

Has anyone successfully tested generated JSF javascript with Http Unit? We are having an issue testing the onChange javascript event on a selectOneMenu.
Here is the JSF cod and generated HTML:
<h:selectOneMenu id="selectLaborCategory"
onchange="#{workordersearch.onchangeLc}"
value="#{workordersearch.selectedPc}">
<f:selectItems
value="#{workordersearch.profitCenters}" />
</h:selectOneMenu>
</h:panelGroup>
<select id="workordersearchForm:selectLaborCategory" name="workordersearchForm:selectLaborCategory" size="1" onchange="document.forms['workordersearchForm']['workordersearchForm:_idcl'].value='workordersearchForm:selectLaborCategory';document.forms['workordersearchForm']['badge'].value='48305';document.forms['workordersearchForm']['li'].value='add';document.forms['workordersearchForm']['start'].value='20040920';document.forms['workordersearchForm'].submit(); return false;">          <option value="-1" selected>Home labor category</option>
          <option value="2">Engineering</option>
          <option value="1">Flight test center</option>
          <option value="0">Not available</option>
          <option value="3">Other</option>
          <option value="4">PCS</option>
</select>
Event 'document.forms['workordersearchForm']['workordersearchForm:_idcl'].value='workordersearchForm:selectLaborCategory';document.forms['workordersearchForm']['badge'].value='97900';document.forms['workordersearchForm']['li'].value='add';document.forms['workordersearchForm']['start'].value='20040920';document.forms['workordersearchForm'].submit(); return false;' failed: org.mozilla.javascript.EvaluatorException: The undefined value has no properties.

Thank You,

Answer 1

I eventually found out what the problem is on this:
Within httpunit v1.5.4, there is a class called com.meterware.httpunit.WebForm$Scriptable implements NamedDelegate. The NamedDelegate provides the getName() method, which looks for the "name" attribute on the form tag.
JSF uses the id attribute instead. To fix this, modify WebForm$Scriptable to also implement IdentifiableDelegate. The IdentifiableDelegate provides the getID() method, which looks for the "id" attribute on the form tag.
public String getID()
return WebForm.this.getID();
Once this code is in place, the javascript cited above works fine.
