Cloves Almeida commented on JBSEAM-1855:
----------------------------------------

For those struggling with this issue, there's a workaround:

String id = event.getComponent().getParent().getClientId(FacesContext.getCurrentInstance());
FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, "your message", null);
FacesContext.getCurrentInstance().addMessage(id, msg);

I second that there should be a FacesMessages.addToControlByClientId, or at least be better documented.

> It is possible do add FacesMessages via the Seam functionality with FacesMessages.instance().addToControl. In the parameters you have to pass the component id. In the plain JSF way, you can add FacesMessages via FacesContext ... addMessage. In the JSF-way you have to pass the client-id.
> With normal input components you can use both ways. But when you work with datatables, you MUST work with the client-id, the Seam-way with using only the component-id does NOT work.
> Explanation: When using a datatable-tag, you only have one component. The renderer generates the various rows. In the component-tree there is yet only one component! If you want to add a FacesMessage to one row, you can only work with client-ids (because you have to include the row-index). 
> My wish: Please change FacesMessages.instance().addToControl. for using with client-ids.
