Question

<c:if test="${config.update and not config.caseUpdate}">
        <html:submit property="userComments" style="width:200px" styleId="addCommentsBtn">
               <bean:message key="button.update.case"/>
        </html:submit>
</c:if>

I am confusing about this working mechanism . Can you please explain on if condition.

Answer 1

this will execute

<html:submit property="userComments" style="width:200px" styleId="addCommentsBtn">
<bean:message key="button.update.case.with.comments"/>
</html:submit>


only when config.update will true and config.caseUpdate will false

example

<c:if test='condition'>
Generate some template text
</c:if>

if condition is true it will display template text.

if you want to display gender as male if condition is gender male then you can print male in c:if
