I don't know of one. It's common to make your own, eg. ShowError.html:
<span jwcid="$content$">
<span jwcid="@If"
condition="ognl:page.beans.validationDelegate.hasErrors">
<span class="error">
<span jwcid="@Delegator"
delegate="ognl:page.beans.validationDelegate.firstError">Error
Message</span>
</span>
</span>
</span>
and perhaps a more generalised message component, eg. ShowMessages.html:
<span jwcid="$content$">
<span jwcid="@If"
condition="ognl:page.beans.validationDelegate.hasErrors">
<span jwcid="@ShowError">--- Validation error message ---</span>
</span>
<span jwcid="@If" condition="ognl:page.warningMessage">
<span jwcid="@Insert" value="ognl:page.warningMessage"
class="warning">--- Warning message ---</span>
</span>
<span jwcid="@If" condition="ognl:page.infoMessage">
<span jwcid="@Insert" value="ognl:page.infoMessage"
class="info">--- Info message ---</span>
</span>
</span>
Don't forget to create ShowError.jwc and ShowMessages.html, both of
which would look like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE component-specification PUBLIC
"-//Apache Software Foundation//Tapestry Specification 4.0//EN"
"http://jakarta.apache.org/tapestry/dtd/Tapestry_4_0.dtd";>
<component-specification allow-informal-parameters="no">
</component-specification>
BTW, getters and setters for warningMessage and infoMessage are
typically put in a common superclass of your pages so that every page
can use them.

Dear all,
Is there any Message component in T4 for displaying messages on pages
upon success or failed process? Or should I use Insert component
instead?
Thanks in advance.
