Can't open editors with 6.1 and Eclipse 3.1

[jlweb58]

I just updated to Oxygen 6.1 in my Eclipse 3.1 installation. Until now I was using Oxygen 5.1 with Eclipse 3.1. Now Oxygen fails to open most XML files with the following stack trace:

I tried deleting the oxygen 5.0.0 and 5.1.0 directories from my eclipse plugin directory, but that made no difference.

I'm running Eclipse 3.1 GTK on SuSE Pro 9.0

Any idea what's causing this? It's quite strange, since Oxygen 5.1 worked with Eclipse 3.1 (except for occasional stability problems)

Hi,

You are not using oXygen, you are using XML Buddy, see the stacktrace, the exception is in the code of that plugin:

java.lang.NullPointerException
at com.objfac.xmleditor.partition.Partitioner.documentChanged2(Partitioner.java)

To make sure you open oXygen use the Open with... contextual action and choose oXygen XML Editor.


Best Regards,
George

Thank you, George, you were quite right - although I did open the XML files with oXygen, it seems XML Buddy was interfering. After closing Eclipse, deleting XML Buddy from my plugin directory and restarting, everything was OK.
