RE: Tag Iterate !!!
I have the same problem. It doesn't look like the iterate tag creates the
bean declared with the id attribute.

Based on what you are showing in your email, everything looks OK. I don't
think the problem is with the iterate tag. The message
"javax.servlet.ServletException: Cannot find bean client in scope null"
would have to be coming from bean:write which is looking for a bean called
client. It's looking in all scopes (null just means you didn't specify a
scope), so you don't need to add a scope. The iterate tag should put a bean
in the page scope with the name client.
Are you sure that it is the bean:write tag inside the iterate tag that is
causing the error or is there something else on the JSP that you aren't
showing? Try removing the bean:write from the iterate tag and replacing it
with some html.

Re: Tag Iterate !!!
Posted by Luis Olivares <ol...@infosphere.com>.
In fact, the Iterate Tag doesn't put such bean in any scope.
I have tried to use the Equals/NotEquals Tag inside an Iteration Tag and I
simply cannot look inside the property of my 'Iterated Bean' to do the
comparision.
I ended inserting a scriptlet and 'manually' defining the bean resulted from
the Iteration, something like this:
<%
String lastDepartment = "";
%>
<logic:iterate id="document" name="documents" scope="request" >
<bean:define id="department" name="document"
property="department" toScope="request" />
<logic:notEqual name="department" scope="request"
value="<%=lastDepartment%>">
Here I print a Title (DepartmentName) when the next
Iteration comes with a Different Department
<%
lastDepartment = department.toString();
%>
</logic:notEqual>
<br>
<bean:write name="document" property="title"
filter="true"/>: <bean:write name="document" property="description"
filter="true"/>:
</logic:iterate>
So I think each Iteration you get its in managed in Memory, not in any
scope.
Am I wrong? Is this the correct behavior of the Iterate Tag? Will this be
fixed?.
Regards.
