Re: __LINK_TARGET__ changed to _link_hidden_?
You could use the forceId attribute of the t:inputHidden component.
For instance:
<t:inputHidden id="myId" forceId="true" />
will render a input type="hidden" component with clientId 'myId'. So
you can use this id safely in your code...

Yes, that is..

Unfortunately, this isn't legal JSF.
You'd have to use h:commandLink instead of h:commandButton.
h:commandButton does not take f:param values.

Re: __LINK_TARGET__ changed to _link_hidden_?

So, your interest is to pass some values to the next page? Then it is
not necessary to use the inputHidden components. If you want, you can
pass the parameters with the command component and do whatever logic
you need with this parameters in the backing bean:
<h:commandButton value="Send"
actionListener="#{yourBean.doSomethingWithTheParams}" action="rBean">
<f:param name="raId" value="#{var.ra}"/>
<f:param name="rbId" value="#{var.rb}"/>
<f:param name="rcId" value="#{var.rc}"/>
</h:commandButton>
You can also use t:updateActionListener component to implement faster
a master-detail effect. See the example [1] to see how it works.

hmm.. not exactly. See:
...
<h:column>
<h:form>
<t:inputHidden id="raId" forceId="true" value="#{var.ra}"/>
<t:inputHidden id="rbId" forceId="true" value="#{var.rb}"/>
<t:inputHidden id="rcId" forceId="true" value="#{var.rc}"/>
<h:commandButton value="Send" action="rBean"/>
</h:form>
</h:column>
...
(ra, rb and rc comes from a database)
The last column of this table has buttons, on every row.
When clicked, this page must send the data (ra, rb and rc values) to
another page/servlet/class/etc..
On that class, the target that receive the request, I need get these values.
How to access "raId" or "rbId" or "rcId" on the java code to work with
its value (ra, rb or rc)?
Thanks,

Re: __LINK_TARGET__ changed to _link_hidden_?

I am not sure if I understand what you mean, but you can use
forceId/forceIdIndex also inside dataTables. The next snipped comes
from the myfaces examples [1]:
<t:dataTable value="#{forceIdBean.choices}" var="choice">
<h:column>
<t:inputText id="widget" value="#{choice}"
forceId="true" forceIdIndex="true"/>
</h:column>
</t:dataTable>
Then, you can access to your element using the id widget[x], where x
is the index...
Hope that helps,

Hi Bruno.
How to use this id on the code?
Suppose:
... <h:dataTable... var="users" ... <h:column> ...
<t:inputHidden id="myId" forceId="true" value="#{users.name}"/>
...
where "name" is coming from a database. How to use "myId" and its
value on a target page/bean?
Thanks a lot,
