> I've just tried NetBeans 11.2 for PHP projects and this version appears to be 
> unusable for PHP due to lots of NPE errors, which in effect prevent the Enter 
> key from working in the editor. It looks like certain code structures trigger 
> the NPE's. So far I've come across them in js and tpl (Smarty) files. And I 
> have a way of reproducing the problem:
>  # Create a new PHP project or open an existing one.
>  # Create a new Smarty .tpl file (or open an existing one).
>  # In the editor paste this code:
> {code:java}
> <a {if $smarty.server.REQUEST_URI|strstr:"/new"}class="underline"{/if} 
> href="{url('new')}">{code}
>  # Try pressing Enter anywhere in the editor - an NPE comes up and the Enter 
> key does not work.
> There seem to be more code samples that trigger the error but for now I'm 
> reporting the first one that caught my attention. Here is the error:

> I'm using Windows 10 64-bit and the zipped Netbeans 11.2. I tried running onĀ 
> jdk 11.0.1 and 13.0.1 - didn't make any difference. The error occurs even on 
> fresh NetBeans installation (without importing previous settings) without any 
> plugins apart from the default PHP plugins available under the "PHP" checkbox 
> under Plugins/Installed tab.
> I don't know exactly when the bug first appeared since I skipped 11.1. I'm 
> now back to 11.0.
