Hi,
I am using <logic:equal> tag to show a different display on a jsp page.If move on the next page and come back to the same page,I am getting the perfectly expected behavior.
Incase I change the value of the property in the <logic:equal> tag,can I reload the updated contents
or in other words,can anyone tell me how update the page once the value of the property in the <logic:equal> tag is changed.

Thanks
