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:
<html:select property="supplyList" multiple="true"
size="5" styleClass="Campos" style="width:150">
<logic:present property="supplyColl" >
<html:optionsCollection property="supplyColl"
value="value" label="label"/>
</logic:present>
</html:select>
supplyColl is a collection of LabelValueBean.
