Hello all.
I want displaytag to create a dynamic link for me. Currently, the only
way that I can do this is to use a decorator. However, I would prefer
using the struts-like approach.
The situation is this: I have a collection of classes, where each class
has two attributes, id and description. I want to show the description
in a table, and hyperlink it using the id, something like this:
<a href="MyAction.do?index=45">This is the Description</a>
Therefore, I have the following table definition:
<display:table
list="${MyForm.collection}"
sort="list"
requestURI="MyAction.do"
>
<display:column
property="description"
sortable="true"
title="The Description"
href="MyAction.do"
paramId="index"
/>
</display:table>
Now, the above definition creates the following cell entry:
<a href="MyAction.do?index=This is the description">This is the
description</a>
If I add a paramName attribute like this to the display:column:
<display:column
...
paramName="id"
it looks for an attribute in the current scope, whose name is 'id'.
This isn't what I was expecting. I was hoping that it was going to find
the parameter of the current ROW, and put it's value into the request.
So, to summarize, how do I use the struts-like dynamic link generator to
create a URL based on the current row, where if I have a class with
attributes:
description="this is the description"
id=45
the resulting URL is:
<a href="MyAction.do?index=45">This is the Description</a>
Thanks
