Please see following excerpt from a thrown exception I currently try to fix but I'm confused where (JSF template/view) it origins from.

        at javax.faces.component.UIComponentBase.validateId(
        at javax.faces.component.UIComponentBase.setId(
        at com.sun.faces.facelets.tag.jsf.ComponentTagHandlerDelegateImpl.assignUniqueId(

It would be nice to have some message being added to that exception, like: Invalid id x/y$z or so then I can directly see where that exception comes from (one of my templates, of course).

JSF 2.3.5

@Quix0r Quix0r changed the title from UIComponentBase.validateId() thrown exception should contain some text to UIComponentBase.validateId() thrown exception should be more explanatory Jul 7, 2018

Any news here? I would really appreciate if this issue is quickly solved (and no big change, for sure). Maybe I can find some time to do it myself but no promise here.
