I have an iterate question as well, and nobody has responded to my first =
3 emails, so maybe I will try here:

I have a simiar issue that I can't resolve and was hoping you could =
help.
I have this logic iterate that does not print anything out even though =
there are 3 beans in my UserContact[]:

<bean:define id=3D"state" name=3D"contactListForm" =
property=3D"userContacts" />


    <logic:present scope=3D"request" name=3D"contactListForm" >
        <html:select property=3D"userContacts" >
        <html:option value=3D"" key=3D"form.select"/>
            <logic:iterate id=3D"contact" name=3D"contactListForm" =
property=3D"userContacts">
                <html:options value=3D'<bean:write name=3D"contact" =
property=3D"contactId" />'>
            </logic:iterate>
        </html:form>
    </logic:present>

    <logic:notPresent scope=3D"request" name=3D"contactListForm" >
        <b><font color=3D"red">NO CONTACTS CREATED YET. PLEASE CREATE AT =
LEAST ONE CONTACT!</font></b>
    </logic:notPresent>

Gandle,

 Thanks again for the reply, but I guess your code
tests if a property of a collection is not null. What
I need is really test if the collection object, that
is a DynaActionForm property, is null. Following is
the code where I use this:
=20
  <html:select property=3D"supplyList" multiple=3D"true"
size=3D"5" styleClass=3D"Campos" style=3D"width:150">
    <logic:present property=3D"supplyColl" >
       <html:optionsCollection property=3D"supplyColl"=20
value=3D"value" label=3D"label"/> =20
    </logic:present>=20
  </html:select>=20

  supplyColl is a collection of LabelValueBean.
=20
  Caroline
