AgileTrack gets a nullpointerexception error on execution

The program runs fine on several computers, but on about a dozen we always get a java.lang.nullpinterexception at agiletrack.client.view.widgets.tray.issuepannel.isvalid(issuepanel.java:1573) every time we try to run the program. What gives? We have the latest and greatest Java version on the machine and other users can connect to the database just fine.

The error line number suggests that a text field widget is somehow not fully initialized, but I have not reproduced the error.

Could you provide more information about the error—what operating system is being used, and the specific Java version? Additional logging may also be found in the agiletrack directory in the file agiletrack.log or agiletrack-info.log. Please post any complete stack traces in those files.

Thanks.

Hello, the machines having the error are two workstations and a server. The workstations are clones, both running XP SP3, 64 bit edition with the latest version of Java (1.6). The server is running Windows Server 2003 R2 Enterprise edition, 32 bit. Below is the agiletrack-client.log and the agiletrack-info.log (there is no agiletrack.log in the program folder). I have successfully run the program using my Dell laptop, running XP SP3 64 bit edition. We are connecting to a SQL server and I've verified that the settings are correct on the nonfunctional workstations and server.

Thanks for the extra information. It turns out that this problem has come once before somewhat recently. I suspect something must have changed in recent Java releases which is causing the error to occur.

In the next release that is due to come out in the near future, the problem is fixed. Here is a link to a pre-release build that you can use.

http://agiletrack.net/agiletrack-client-1.2.2.zip

Just extract the contents into your agiletrack directory and things should work. I hope that helps.
