message for input text in table

[fabdib]

Hi to everyone,
i've a richfaces:dataTable with input text for colum for example:

<rich:dataTable id="posasList">
.......
<rich:column style="width: 70px">
<f:facet name="header">
<h:outputText styleClass="tableHeader" value="Head"/>
</f:facet>
<h:inputText id="posConiug"
value="#{posas.posConiug}"
styleClass="tableContent" >
<a:support event="onchange" ajaxSingle="true"/>
<a:support event="onblur" reRender="totParz0" />
<f:convertNumber integerOnly="true" />
<f:validateLongRange minimum="0"/>
</h:inputText>
</rich:column>

..........
</rich:dataTable>

So i want to show a message when the value of input text is <0 or is a character;

How i can do it?

Thanks,
Fabio
