b:inputText null object not working till 3rd level #851

Tobias5 · 2017-08-29T08:24:13Z

Hi,
please see the following example:

<b:inputText id="terminologyId" value="#{allowedTerminologiesBean.terminologyToEdit.terminologyKey.terminologyId}"/>

The "terminologyToEdit" is null.

With h:inputText it is working fine. It also works if I remove the last field, but sure, that is not what I need:

<b:inputText id="terminologyId" value="#{allowedTerminologiesBean.terminologyToEdit.terminologyKey}"/>

But it seems to be dependent on the level of accessing fields.

The following exception is thrown:

BootsFaces tries to read the JSF303 annotations. That's only possible if the field is not null. Do you really need it to be null?

Tobias5 · 2017-08-30T07:49:13Z

Thanks for the information, that makes sense. So no bug but a feature?
I have to restructure my code to avoid that exception. I have a modal to edit/modify an existing object that was selected by the user. If there is no selected object, it's not displayed and the objects are null.

stephanrauh · 2017-08-30T18:04:42Z

I wouldn't call the bug a feature, but it's caused by a feature. Until now, we got away with it. If more people vote for avoiding the NPE, we'd certainly do so.

ggam · 2017-08-30T18:09:19Z

If EL can handle this, I think we should try to mimic it. I haven't read the EL spec thorougly but I think it specifically says it ignores those null pointer exceptions. So people might righfulu rely on it. I'd vote for fixing it too. El mié., 30 de agosto de 2017 20:04, Stephan Rauh <notifications@github.com> escribió:

As a side-effect of #846, I've been able to solve this ticket, too. I've uploaded a new developer snapshot of BootsFaces 1.2.0 to Maven Central. See #369 on how to get it.

Please test if your bug is fixed by this update and report back.

Thanks in advance!
