Generating unique IDs inside dataTable

[Hussein Baghdadi]

Hi.
Inside my dataTable I have inputText components.
How to assign a unique ID for each inputText (so I can assign message component for each one of them)?
Thanks.

It happens automatically. The dataTable uses your ID as a model, but the full ID is decorated to make it unique.

In th case of JSF message components, things (again) are handled automatically. If you're generating your own message, it needs to be a property for the row of the model that your dataTable is displaying.

But this way I'm forced to:

<h:column>
  <f:facet name="header"/>
  <h:inputText id="po" />
  <h:message for="po" />
</h:column>

While I'm looking for:

<h:column>
  <f:facet name="header"/>
  <h:inputText id="po" />
</h:column>
<h:column>
  <f:facet name="header"/>
  <h:message for="po" />
</h:column>

In the later case, nothing is displayed.
