Hi Simon,Yes, that was exactly the point. It's as easy as adding all the children, and at the end of the tree component creation, call to getClientId().Thanks a lot for your support.

I believe Volker's answer is exactly what you're looking for.
I have been implementing the dynamic creation of my tree component as you mentioned, i.e. adding all the components to their parents before calling getClientId().But it seems that there is something more to do, looking at the generated code:
input id=tablaEdicionPuntuaciones0_0:_id30_0:_input

Hi Enrique,
the '_0' is added by the datatable while rendering row 1 (index 0).
This is needed to generate uniqe ids over multiple rows.
Looks like you have nested datatables?
To get the '_0' you can call setRowIndex(0) on the datatable component,
but if your table contains more rows the ids
Well, the problem is that I'm creating the table in code using a DataModel for columns and a DataModel for rows, so at that time the row index is not known, is it?And as I assign the client ID at code, how can I know the row?

BTW: if i remember correct the generated row index is changed to ':0' in
svn.

If your component is a column in a table, and the table has 5 rows then
there will be 5 HTML tags generated for that component. Each needs a
distinct id according to the rules for HTML.

Hi Enrique!
But this is what Simon tries to show you.
Its possible to inject the other bean instance or to look it up through
the context.

Hi,
you can get the rendered 'htmlId' of a component by
component.getCientId(facesContext);
so you can do :
UIOutput texto5 = (HtmlOutputText) FacesUtils.getApplication()
.createComponent(HtmlOutputText.COMPONENT_TYPE);
texto5.getAttributes().put(onclick,
validate(' +
I tried that, but at the time of creating the component in code, texto4.getClientId(facesContext) returns exactly the same used before when texto4.setId(_input), so it doesn't help at all

Hi,you can get the rendered 'htmlId' of a component
See what is generated at runtime:input id=bodySubview:_id23:tablaEdicionPuntuaciones0_1:_id24_4_0:_input
name=bodySubview:_id23:tablaEdicionPuntuaciones0_1:_id24_4_0:_input type=
text value=12 onclick=myAlert(_input.value)
class=txt /And obviously, a component with _input ID does not exist,
After adding the component to the component tree the full id should
returned. The structure of the tree is needed to create this id.
This is what is done when rendering the 'htlmId' in the renderer.
Without the tree structue there is no way to find the resulting clientId.

So your answer means that there is no way to accomplish what I am trying, isn't it?Maybe using some kind of events, when the component is created to advise another one or so?2006/1/19, Volker Weber

I've misunderstood your question, method getClientId is what you want;
you just need to make sure the component is attached to the view tree
before calling that method.
ie:
UIOutput texto4 = createComponent(..);
No he says: You need to add the component to its parent
component before you can receive a
usefull clientId.
