Failed to register / NullPointerException #92

Closed nmaas87 closed 3 years ago

nmaas87 commented 3 years ago

Hi there, I used the latest YAMCS Studio 1.5.0 and get following error(s) as soon as I open my displays in the Display Runner:

[09:08:12.967] Failed to register round.js. 
java.lang.NullPointerException

There are several in that style, but I just copied one...

I use serval js scripts with the "linked" / choose script file format in widgets. For example, the round.js has this content 

importPackage(Packages.org.csstudio.opibuilder.scriptUtil);
var number = PVUtil.getString(pvs[0]);
widget.setValue((Math.round(number * 100 )/100));

and does basically "round" the inputs / PVs. I got several of this NullPointerExceptions in the new studio version, the older rc1 did work without problems. All widgets that imply such script do not work anymore / no PVs are working, hence I cannot use the 1.5.0 and need to go back to the 1.4.0 rc1...

Could you look if you find an error and how to solve the issue?

Thank you very much!

Nico

Thanks for reporting. I will investigate and fix. There were pretty radical changes to the PV core, but we do want to remain compatible.

Workaround is probably similar to what I did in this commit: https://github.com/yamcs/yamcs-studio/commit/b93050a6190e9542d2c0c9fd4654a6f2878d0110

When I did that commit, I wasn't sure if it was an issue in my new code, or rather in that script, but I guess I know the answer to that now.

nmaas87 commented 3 years ago

Don't worry, stuff happens. Thats why we test and report to fix issues and get a more stable product :)

nmaas87 commented 3 years ago

I tried your work-aroud on my round.js

importPackage(Packages.org.csstudio.opibuilder.scriptUtil);

if (pvs[0].getValue() == null) {
    widget.setValue(0.0);
    widget.setPropertyValue("tooltip", "no value");
} else {
    var number = PVUtil.getString(pvs[0]);
    widget.setValue((Math.round(number * 100 )/100));
}

It did not work, still same error on 1.5.0.

This is on my todo list for the next release, but need to dedicate some time to it.

I have one reproduction case already, but want to make sure I cover also your particular reporting.

When I was first looking at your script, I was also making the reflection why you weren't just using a formula PV. But then I noticed that this does not support the round function yet... So I will add that in the next release too and then you should have the shorter alternative solution to just use a PV set to =round('/my/parameter'*100)/100

1.) Yes I have, here is a full snippet of one of those errors for round.js

2.) When I start Yamcs Studio 1.5.0, its already in the Display Runner mode and the errors popup. I am not yet connected at this moment to the Yamcs Server. And after connecting, the errors don't go away / i.e. the widgets which use the round.js do not work and don't show any telemetry at all, only right click on a widget, "Show PV info" gives Realtime data.

3.) round function: Thank you very much, that will be very useful and welcome :)! I thought about this as well, but did not wanted to make a fuzz about it ;)

OK, those traces exposed that the JavaScript engine is not working at all in v1.5.0. It comes from the change to bundle a minimal JRE. I pushed a fix for it for a release probably tomorrow (pending other work).

I should have noticed it earlier, but I usually test in development mode, and that workflow did not expose this particular problem.
