Re: [displaytag-user] Dynamic Column Creation

[jill j. <jil...@gm...>]

I am sorry, I think I conveyed my need differently. I do not need a
decorator.

My need is to create columns from database.

My need is 4 static columns but rest all columns coming fro database.

So I have build 2 beans for that.
bean1 -- name, value from database.

Bean 2 - 4 static columns + arraylist of bean1
in request i store arraylist of bean2.

my jsp code is this


<display:table name=3D"bean2" >
   <display:column property=3D"name"  title=3D"School Name" ></display:colu=
mn>

    <c:forEach var=3D"cl" items=3D"bean2.bean1">
      <display:column title=3D"${cl.title}" property=3D"${cl.value}"  />
    </c:forEach>

   <display:column property=3D"allocatedAmt"  format=3D"{0,number,0,000.00}=
 $"
title=3D"Total Allocated $" ></display:column>
   <display:column property=3D"totalOfAllPrograms"  format=3D"{0,number,0,0=
00.00}
$" title=3D"Current Total $" ></display:column>
   <display:column property=3D"difference"  format=3D"{0,number,0,000.00} $=
"
title=3D"Difference" ></display:column>
</display:table>





But with below code i get following error

Error looking up property "${cl.currYearExpenditure}" in object type bean2

So it is not gonig to bean1. it is looking for the object in bean2.



Any help will be appreciated.



Thanks and regards,

Jill.
