This defines a field in an HTML form, server knows nothing about it.

This is evaluated on server before HTML page generated, browser knows
nothing about it.

JSTL hides the error, it does not blow up when it cannot find an object.

If you want to update HTML page without submitting it to the server,
then use some Javascript. If you submit form each time an operation is
changed, add an "operation" field to your form bean and use
<logic:equal name="${myFormBean.operation}" value="update">
when you re-render the HTML page.
