Hi David,
Here is an example. In this example, homeDepartmentRoles is a String[],
representing all of the roles that a particular user has. The "roles"
collection in the <html:options> tag is a Collection of LabelValueBean
objects (see
http://jakarta.apache.org/struts/api/org/apache/struts/util/LabelValueBean.h
tml). The LabelValueBean objects in the collection represent ALL items in
the select list. To put it another way, the collection specified in the
<html:options> tag should have ALL items you want to display in your select
box, whereas the <html:select> "property" attribute is the array that stores
all items which will show up selected when the select box is displayed.
<html:select property="homeDepartmentRoles" multiple="true">
<html:options collection="roles" property="label"
labelProperty="value"/>
</html:select>
This can be done a number of different ways, but this is the best way that I
have found works for my needs.
HTH,
Justin
