Re: AssertionError at org.netbeans.api.visual.widget.Widget.addChild
Hi I will try again, I made an attempt to code, this but it also threw an
error, I need to turn on some debugging to see the variable state. I will
send you what I tried. Also, this feature is also platform dependent, it
does exist on MacOS and maybe neither on Linux. It exist on Windows
platform. I have verified on Windows and MacOS.

Hi Dev:
I will be able to check on that system later today, to see where I
receive the plugin from.

Strictly speaking, working with VisualLibrary off EDT thread might be
eventually valid - but then it's your responsibility to properly lock
between your manipulation thread and the EDT painting which uses the
same data strucures.
The Graphics Class View does not such locking and I am really not sure
if such locking is possible: the Visual Library itself registers e.g.
MouseListeners, ComponentListeners which runs in EDT, traverses widget
hierarchy and do not allow for any synchronization or locking.
So I think the assert I've added is obtrusive, but correct.
-S.

Where exactly did you get the Graphics Class View from? Plugins?
Looking at the recent history of Widget::addChild I think this is caused by
the added assertion to check it's being called on the EDT (which is line
218!). It looks like that plugin is adding widgets off the EDT? That's a
bug in the plugin not the Visual Library then.
Best wishes,

Hi Dev:
I reported this on

I changed the priority to Minor.

Re: AssertionError at org.netbeans.api.visual.widget.Widget.addChild
Posted by Efrem Mc <ef...@gmail.com>.
Okay, I am going to look at previous NB 7/8. I am not sure when it
was introduced in NB 8.x? The visual library is something I would
need to test independently as I think it works.
I need to learn and know how this feature should work. When I have a
really simple program created by GUI Builder with a view controls, I
initiate the popup, select Graphical View,
It threw this:

I just checked NB 8.2 and the feature is not there so this might be
new for NB 9.0. Maybe it was an addin plugin for NB 7/8?
Do you have a working sample? You should be able to reproduce it. I
created a Java App, created a new JFrame Form, added a few controls,
then tried Graphical View. I currently have build 406, and I switched
my default to JDK10, but it does with JDK8 as will. It is something
in the code. I attached a picture.
Please advise,

Am I missing something here? What's broken in the visual library? It looks
like the bug is in the code calling that, and the assertion error is
correctly being triggered?
