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('" + texto4.getClientId(facesContext) + "')");
Regards,
Volker
