PHP editor behaviour

Hi all,

I'm using Netbeans-PHP platform and got some strange editor behaviour when working on laravel blade templates.

Sometimes when typing open curly brackets it is not possible to type any more brackets. Characters can't be deleted after an opened curly bracket, nevertheless the file is marked as changed, while trying this. While typing doesn't work, copy and pasting characters do.

See comments in screenshot for details. 

This behaviour is not always reproducible. Sometimes it helps closing and re-opening the file.

Tried to switch off auto bracket completion with no effect.

Never had this behaviour with previous Netbeans-IDE versions.

Please, provide exact steps to reproduce and attach a sample file or a sample project we can use to investigate. Also, it is always a good idea to attach the IDE log [1] once any error occurs.

Simply reopen this issue, thanks.

example file with mostly reproducible behaviour

Just updated PHP-Netbeans IDE from 8.1 to 8.2 on another system (x64/Win7Pro) instead of (x32/Win7Enterprise), mostly the same behaviour as described initially.

Open attached example file in PHP-Netabeans, go to nearly any line and try typing more than one { will not be possible

Go to lines 58, 66, 74, 82,  which already contains a template var statement {{ $ var }} . It's possible to type two {{ but afterwards it's not possible to type a - sign for a template comment i.e. {{-- this is a comment --}}

Type the -- anywhere else on the page, copy it, paste it after the {{ will work. But try to delete the pasted -- with backspace won't.

Thanks a lot.

I can see NPEs in the attached log - reassigning, please evaluate. Thanks.

Not sure where lexer belongs. Thanks.

I have also actually had this error myself in 8.1 and upgraded to 8.2 in the hopes it would resolve the problem, so the defect goes back a while.

Hi All, 

Recently switched from Netbeans PHP 8.1 to 8.2 version. When working with laravel template codes like {{ editor does not work as expected. After typing {{ braces, I unable to type other character and unable to Undo last typed charactes. I haven't faced this problem earlier 8.1 version. Please suggest me to solve this problem. 

Thanks to all

I can confirm this too. 

The problem can be easly reproduced when typing two curly brackets one after another in HTML DOM attribute's section and results in "A java.lang.IndexOutOfBoundsException exception has occurred." error.

I hope this can be fixed as soon as possible because it's impossible to work with PHP files that got HTML inside of them.

Okay, after doing a bit more of testing with a latest snapshot (Netbeans IDE Dev 201706110001) I have noticed that after deactivating "Knockout HTML Editor" an error is no more present in some of blade templates (but it's not being resolved completely). Also, there is a strange behaviour and it seems to be happening only when typing two sequel opening curly braces in HTML DOM attribute section - two open curly braces get auto-completed with a single closing curly brace e.g. <div class="{{}"> (this only happens if no error occures). I hope this helps.
Comment 12 CyberDyne 2017-06-12 05:40:15 UTC
A follow up - it seems disabling "Knockout HTML Editor" and "Angular JS Editor" plugins prevents from error occuring... also the strange auto-complete happens mostly on class or style DOM attributes, while it's not present on other HTML DOM attributes.

Just wanted to give a huge thank you to CyberDyne for finding the work around to this bug. I'm just in the process of getting to grips with Laravel and this bug certainly made the experience a lot more frustrating.

The bug also prevents a backspace input if the user inputs two instances of an open and closing curly brace {}{} and you try to delete the first closing curly brace such that the resulting text would become {{}

For what its worth you can also get around the bug by typing an opening curly brace followed by a space then the second, then go back and delete the space.

Thank you! I'm using NetBeans 8.2 on Windows 10 coding a Laravel PHP project with Blade templates (.blade.php files), and they were driving me crazy because pressing Enter would never add a new line. (Sort of like reported here:

After deactivating plugins "Knockout HTML Editor" and "Angular JS Editor" (and restarting NetBeans), it seems to work.
