Mike,
If I understand you correctly, you have a bean that contains an arraylist which also contains an arraylist?....
If this is the case, I just resolved this issue myself. I have bean A that contains a ArrayList getOtherArrayList() method.... the other arraylist contains attributes of another bean (bean B).... and to further compound the issues... bean B contains an arraylist that contains a ArrayList with is attributes of yet another bean.
I needed to display all of the contents and it resulted in a nested iterate tag. If this is want you are wanting to do let me know and I can send you the example I used....

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.
