Inside the struts-exercise-taglib.war that comes with struts 1.1 you will
find a pratical example to solve your problem...
You should not do a logic:iterate inside html:select, insteat of
logic:iterate use the option:optionsCollection and pass your collection to
it...
look the jsp example ....
Vector options = new Vector();
options.add(new LabelValueBean("Label 0", "Value 0"));
options.add(new LabelValueBean("Label 1", "Value 1"));
options.add(new LabelValueBean("Label 2", "Value 2"));
options.add(new LabelValueBean("Label 3", "Value 3"));
options.add(new LabelValueBean("Label 4", "Value 4"));
options.add(new LabelValueBean("Label 5", "Value 5"));
options.add(new LabelValueBean("Label 6", "Value 6"));
options.add(new LabelValueBean("Label 7", "Value 7"));
options.add(new LabelValueBean("Label 8", "Value 8"));
options.add(new LabelValueBean("Label 9", "Value 9"));
pageContext.setAttribute("options", options);
<html:select property="collectionSelect" size="10" multiple="true">
<html:options collection="options" property="value"
labelProperty="label"/>
</html:select>
or
<jsp:useBean id="testbean" scope="session"
class="org.apache.struts.webapp.exercise.TestBean"/>
<html:select property="beanCollectionSelect" size="10"
multiple="true">
<html:optionsCollection name="testbean" property="beanCollection"/>
</html:select>

Assunto: html:select tag or logic:iterate
Hi all,
I am quite new to struts tag library and I need an advice.
In the HttpSession I have an object of type Collection, which stores
a list of MyObject.
MyOBject has two properties, description and id.
Out of this Collection of MyObject I must generate a selectable list
Which displays MyObject names, (wity MyObject.id as value)
I have tried to embed the html:select inside a logic:iterate, but my
editor (websphere studio)complaints for following code
<html:select property="defaultContainerType" multiple="no">
<logic:iterate collection="<%=
(Collection)session.getAttribute("CONTAINER_TYPES")%>" id="container">
<html:option value="<bean:write name="container"
property="type"/>">
<bean:write name="container"
property="description"/>
</html:option>
</logic:iterate>
</html:select>
the error is 'Attribute container has no value'
anyone has a suggestion on how to solve my problem?
Fact is that the Collection is stored in the session, not in a
JavaBean..
Thanks and regards
marco
