Multiple hidden form fileds gettting submitted, using checkbox decorator
------------------------------------------------------------------------

                 Key: DISPL-647
                 URL: http://jira.codehaus.org/browse/DISPL-647
             Project: DisplayTag
          Issue Type: Bug
          Components: Decorators
    Affects Versions: 1.2
            Reporter: Sonali K
         Attachments: DisplaySearch.JPG

I am using display tag with spring.

I have a search page where in the result display section I am using displaytg.
One of my requirement is to have a checkbox added as first column of the table 
and I am using CheckBoxDecorator for the same.
As per the instructions I have kept my display tag in the form tag and name of 
the form is passed in the form variable.

Now as per my design I enter search attributes which are text fields and hit 
search and the form gets submitted, every thing works fine first time I hit 
Search and results return, from next time all my input form fields start 
getting increased by number of times its getting submitted.

Like for second time one of the field SearchName is submitted as NewSearch, 
second time its NewSearch, NewSearch and third time NewSearch, NewSearch, 
NewSearch.

When I check my generated page I find out that the display tag keeps adding the 
Input hidden variable for each submission, as my code works just fine with out 
this form field adding to the display tag I am thinking it has some thing to do 
with display tag.

 
My displayTag Table
<display:table name="productList" id="productList"  sort="page" pagesize="10"  
export="true" requestURI="/searchcatalog/searchcatalog.htm" 
                                                decorator="checkboxDecorator"   
excludedParams="_chk" form="command">
 <display:column property="checkbox" media="html" />
