Arranging list data

[Dave Mere]

Hi there,

I have a set of results returned to my jsp as a list of beans. Each bean contains one data field and the name of a thumbnail to find and display. The info needs to be displayed in a fixed table format, like so:

1 2 3 4 5
6 7 8 9 10

I can think of a few ways to acheieve this. For example, set an arbitary variable i to increment with each new record. When i = 6 add another <tr>.
Or, return the results as two sets of 5 and loop through the <logic:iterate> twice so I have two tables.

But both of these seem like applying sticking plasters to a problem that I should really solve! Can anyone suggest a better way of arranging these records in the above format?

Thanks, Dave

Oops - here's the code, formatted a little better . . .

<table border="1" width="200">
 <tr>
  <logic:iterate id="sumAlpine" indexId="alpid"
   type="org.kew.alpine.bo.SumAlpine" name="queryForm" property="results">
    <td>
 
     <html:link href="detailQuery.do" name="queryForm"
       property="searchTerms" paramId="alpkey" paramName="sumAlpine"
       paramProperty="alpkey"> 
 
      <img src="img/thumb/<c;out value="${sumAlpine.thumbnail}"/>.jpg">
 
     </html:link>  
 
    </td> 
  </logic:iterate> 
 </tr>
</table>

Dave: Don't sweat the small stuff. Either of your proposed solutions sounds fine to me. This is presentation logic since all you are doing is displaying data on the page. I would implement this in either the JSP or in my Action Form class.

One of my colleagues gave me the same answer. It works doesn't it? Then do it! Perhaps I'm starting to think too much.

If you want this to work for any number of entries (not just 10 or less) you might consider changing the logic to :

if ((currentIndex % 5) == 0)
... add a new row
