you can either create a component which renders those, usually inside your border (layout) component.

or, (quite dirty IMHO...) , use an xml entity...

or, create the components using an annotation in an interface and let your page classes implement the interface.

no. 1 is the *absolute* *preffered* one, but in some rare cases one could use 2 or 3.

I have several .page files that all look like:

<?xml version="1.0"?>
<!DOCTYPE page-specification PUBLIC "-//Apache Software Foundation//Tapestry Specification 4.0//EN" "http://jakarta.apache.org/tapestry/dtd/Tapestry_4_0.dtd";>
<page-specification>
   <!-- page-specific stuff goes here... -->

   <!-- here is the common stuff -->
   <property name="currField"/>

   <component id="errors" type="For">
     <binding name="source" value="beans.delegate.fieldTracking"/>
     <binding name="value" value="currField"/>
   </component>
     <component id="error" type="Delegator">
     <binding name="delegate" value="currField.errorRenderer"/>
   </component>
     <component id="isInError" type="If">
     <binding name="condition" value="currField.inError"/>
   </component>
</page-specification>

If I move the common stuff into a file (showErrors.txt), how can I then "include" it in each .page file?

As suggested elsewhere, I've already tried:

   <include xlink:href="showErrors.txt">

and also:

<page-specification xmlns:xi="http://www.w3.org/2001/XInclude";>
   ...
   <xi:include href="showErrors.txt" parse="text"/>

Neither of these worked.

There must be an easy way....
