Hi all,
Is there a way to directly reference a complex Object attribute within a JavaBean on a
JSP via the struts-bean tag library?
I have had good luck placing ArrayList objects in the HttpSession, then referencing
them in a JSP:
Action subclass excerpt:
session.setAttribute("projects", projectsArrayList);
JSP excerpt:
<logic:present scope="session" name="projects">
...
<logic:iterate id="project" name="projects">
...
<bean:write name="project" property="name">
<bean:write name="project" property="lastModificationDate">
...
</logic:iterate>
...
</logic:present>
However, I would like to reference an ArrayList that exists within the
projectsArrayList object. I was hoping that perhaps I could do something like this:
fantasy JSP excerpt:
<logic:present scope="session" name="projects">
...
<logic:iterate id="project" name="projects">
...
<bean:write name="project" property="name">
<bean:write name="project" property="lastModificationDate">
...
</logic:iterate>
...
<logic:iterate id="teamMember" name="projects.teamMembers"> <!--FANTASY PART-->
...
<bean:write name="teamMember" property="firstName"> <!--FANTASY PART-->
<bean:write name="teamMember" property="lastName"> <!--FANTASY PART-->
...
</logic:iterate> <!--NEW PART-->
</logic:present>
Or, even better, with nested iterators:
<logic:present scope="session" name="projects">
...
<logic:iterate id="project" name="projects">
...
<bean:write name="project" property="name">
<bean:write name="project" property="lastModificationDate">
...
<logic:iterate id="teamMember" name="projects.teamMembers"> <!--FANTASY PART-->
...
<bean:write name="teamMember" property="firstName"> <!--FANTASY PART-->
<bean:write name="teamMember" property="lastName"> <!--FANTASY PART-->
...
</logic:iterate> <!--FANTASY PART-->
...
</logic:iterate>
</logic:present>
I currently get around this by placing two different Objects into the HttpSession,
then referencing them separately. This workaround is limiting me for newer
functionality, as I need something that keeps the class heirarchy intact.
Is there a way to do this? When I try to use "dot referencing" (projects.TeamMembers),
I get nothing rendered on the JSP page. Am I mangling the reference to a sub-object in
the struts-bean tag library? Is the fantasy code above actually valid?
Thanks in advance for any help.
