Use a decorator:

It's worked great for me.

RE: logic:equal and EdHill Display taglib

[Jerome Jacobsen]

If you're trying to conditionally hyperlink the contents of a certain column
of the current row then you'll have to use a Decorator.  The current row of
the list is not exposed in a scripting variable or scoped variable.  For the
reason why see
http://edhill.its.uiowa.edu/display-examples-0.8/example-imp-objects.jsp

logic:equal and EdHill Display taglib

[Robert Taylor]

Greetings,

I'm currently using EdHills Display taglib to iterate over some search
results and render them
in a table. I would also like to hyper link the contents of a column if
certain conditions apply.
In short, I'm looking for a way to expose the iterator element so that I can
use the
.

Looking at the the code in appears that TableTag publishes the iterator
element to the
pageContext as an attribute named "smartRow" (see getHTMLData()).  This
becomes the default
name if a name is not supplied by ColumnTag. This implies that I should be
able to gain
data access to the "smartRow".

I tried stuff
and I keep getting an exception that says the following:

"javax.servlet.jsp.JspException: No bean found under attribute key smartRow"

I even tried a scriptlet to just print the contents of the element and I'm
getting an NullPointerException (because I call toString() on the object,
which
apparently is null)

Is there an easier way, or am I missing something?
Any advice would be appreciated.

robert

Re: Re: Problem with logic:equal and bean:define

[stephen.chambers]

Pawel,

I appreciate the suggestion, but I couldn't get it to work somehow. It keeps coming 
back with compile errors that java.lang.String is already defined. I put exactly the 
same bean:define tag, albeit with a different value outside and above the logic:equal 
tag.

Which struts are you using 1.0.2 or 1.1 b1?

Hi Stephen,
  If you are interested in why it is happening look at the .java file that is
created by jsp compiler. I've spent some time doing it but eventually I had given
up because there were too many lines of code to analyze. Nevertheless I'm sure
there is an important reason :-).
Despite I don't know why it is happening, I know how to solve the problem and
that is why I'm replying to your email. What you have to do is to define a bean
with the same name outside of any  tag. When you repeat  inside  tag bean's value just changes. And that is all. You can
then use bean as you want.
What you must remember is to keep the same classname of the bean in each
 statement. When you use "value" attribute it is done
automatically, assuming that the classname is java.lang.String. If you use
another attribute (name, property and so on) don't forget to add "type" attribute
as well.

Problem with logic:equal and bean:define

 All,

 When I use the bean:define tag inside a logic:equal, why doesn't the

 Code snippet below:

 
   
 

 Once outside of the logic tags, even out.print(myvar); results in null.

I have the following code

For some reason it is printing out both

Am I missing the point about the "logic:equal" and "logic:notEqual" tags, or
is there a reason this might be happening?

As the error message tells you, this is invalid nesting of tags.  In order
to change the destination of the submit, you will need to create some
JavaScript that does so on the client side, perhaps when the submit button
is presed.  (If you do this, be sure you use the same form bean on all of
the actions, or Struts is likely to get confused.)

Alternatively, you could have the  tag submit to a single
action, (say, "/commonSearch.do") which could then look at the title
property itself and then forward to either "/contractorSearch.do" or
"/supplierSearch.do" appropriately.

Re: logic:equal and nesting

[John Raley]

I run into this kind of thing a lot.  It's a constant reminder that the
tag syntax is not a substitute for the control structures we're used to
in programming languages...

It's ugly, but I would probably handle this with scripting vars:
<% String theAction = null; %>
<%
theAction="contractorSearch.do"; %>

<%
theAction="contractorSearch.do"; %>
