Thanks, this got me in the right direction. I can already create a
fieldValidator successfully. The thing is that I found to create it I need
to have a @InjectComponent("textFieldName") and the only way I know to do
this is inside a page Class.

I resolved this adding a fieldValidator to each of my "Field" object when I
render the page. My code is like this:

<t:loop source="fields" value="currentField" t:formstate="ITERATION">
            <t:if test="currentField.visible">
                <tr>
                    <td><label
for="currentField.fieldName">${currentField.fieldName}:</label>
                    </td>
                    <td><input type="text" t:type="TextField" t:id="field"
                        t:value="currentField.fieldValue"
t:validate="prop:currentField.fieldValidator"/></td>
                </tr>
            </t:if>
 </t:loop>


This works fine except when using InjectComponent I need to give it a
fieldId and since I use a loop I don't really know what the field ID's are
(except that they are ID_0, ID_1, etc..) . This is not critical but in a
presentation point of view it points the errors to the wrong field. Is there
any way to bind a fieldValidator to a field without using InjectComponent in
the page class?


Thanks in advance,
