CSIDE generating null pointer exceptions EVERY 10 SECONDS

Hi,

All of a sudden, CSIDE has just gone squirrelly and no restart I do will fix it. I have restarted, I have rebuild, built clean and nothing is working. I'm using the latest available JAR for CSDIE.

The error I'm getting is this:

Problems occurred when invoking code from plug-in: "org.eclipse.jface".

What on earth should I be looking for? Althought the build clean pushed source across, I get this error now EVERY...10...SECONDS, making it virtually impossible to code.

Thanks in advance.

PS, everything work working fine for days up until about 30 minutes ago.

Hi Hugh - the null pointer you're hitting looks to be resolved in 16.2.8 . As such upgrading (once the permissions are fixed - we aksed the KC team to get on this yesterday (it might already be done (I don't have visibility into permissions on the KC, and so cannot chack this myself))) should resolve.

In the interim: the error is coming from our code while it's parsing a function's signature ( i.e. public function void functionName(args...) ). So if this started recently: have a look through what you've changed since the issue began & see if there's anything funky in lines such as this.

If nothing jumps out, or rolling back your changes isn't an option: please feel free to send over your project & I'll see if I can figure out what is happening (alternately feel free to open a ticket with support).

All the best, Dave

Hi Hugh, as an immediate workaround you can also close the Outline View window directly right of the editor.

I got it to resolve partially (or at least occur less frequently) when I rebooted my server. I still see that null pointer. Looking forward to the new JAR. I did notice that it seemed to be associated with when I'm adding or altering a function prototype and am not yet complete.

Is this resolved in 16.2.8 or you still encounter the problem ?

Stephan_Baumann

That is exactly where it happens - and what is fixed with CSIDE 16.2.8. When you add a new function and add the arguments don't pause typing between argument type and name. I.e. when you start entering a new function and pause typing after something like this:

public function Void testFunction ( Integer

you get NPEs until you enter a name for that Integer parameter.

Or close the Outline View - the faulty code is about updating the Outline, if it is closed it doesn't get updated and the problem code is not called.
