specifying dynamic value for logic:equal

[Srinivasarao Nandiwada <sr...@netscape.net>]

Hi,

Let me briefly explain the problem  - I am using a select box in edit 
page and wanted to use simple text corresponding to the selected value 
in view page. My select box consists of the following :

Label One   ---> value 1
Label Two   ---> value 2
Label Three ---> value 3

I am using html:select and html:options in edit page and it works great. 
  However, my form bean only stores the value of the property, and in 
the view page, I need to convert the value of the property back to 
label. How do I do this without using scriptlets? I thought of using 
logic:iterate and logic:equal tags, but logic:equal tag requires a 
constant value which does not work for me as my select box is generated 
from the values from database. I thought of creating another property 
corresponding to label in form bean, but is there any better solution to 
this?

Thanks,
nsr

In form bean get/setLinkSelectionOption. These are the values
as stored on DB.
User sees the labels.
============================================================
In jsp.
<html:select name="linkListForm" property="linkSelectionOption" >
	<html:options  collection="linkSelectionOptions"
		property="option"
		labelProperty="label" />
</html:select>&nbsp;&nbsp;

===========================================================
