------------------------------------------
Summary: NB 11.2 NullPointerException - Enter key doesn't work in
PHP projects
Key: NETBEANS-3335
URL: https://issues.apache.org/jira/browse/NETBEANS-3335
Project: NetBeans
Issue Type: Bug
Components: php - Editor
Affects Versions: 11.2
Environment: Windows 10 64-bit, JDK 11.0.1 and 13.0.1
Reporter: Michal Koscielny
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 on
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.
