I get the following error when trying to use el to assign value to
collection attribute in struts's
html:options:
javax.servlet.ServletException: Cannot find bean under
name ...
However, it work when I do the following:
1) save the attrColorDTOList to a session:
session.setAttribute("attrColorDTOList"
jspHelper.getAttrList().getAttrColorDTOList())
2) In jsp:
<html:select property="color" >
<html:options collection="attrColorDTOList" property="ID"
labelProperty="shortDesc"/>
</html:select>
As you've discovered, the 'collection' attribute is the _name_ of the
collection, not the collection itself:
http://struts.apache.org/userGuide/struts-html.html#options
"The collection attribute is interpreted as the name of a JSP bean, in some
scope, that itself represents a collection of individual beans, one per
option value to be rendered."
If you can't get <html:options> to cooperate, scroll down the page and look
at <html:optionsCollection>. Sometimes it's easier to figure out what to
use for each attribute with that one.
