#13 Cast exception org.eclipse.ui.views.navigator.ResourceSorter

[Martijn Rutten]

When opening the ODT perspective in Eclipse, I get the following exception from the OCaml Package Explorer:

java.lang.ClassCastException: org.eclipse.ui.views.navigator.ResourceSorter cannot be cast to org.eclipse.ui.views.navigator.ResourceComparator

ODT has not benn tested on Eclipse 3.3, since Eclipse 3.2.2 is the current official release of Eclipse.
I've got to check Eclipse backward compatibility before switching to Eclipse 3.3.

For the moment, you can use Eclipse 3.2.x.

Ok. Thanks for the quick response!

It may help to modify the text on the website under "installation notes", which says:
"If Eclipse is already installed, its version should be at least 3.2. If you don’t have any Eclipse distribution installed, please download the latest version (Eclipse is free)."

I read this as that 3.3 would also be supported...

I hoped I had time to test ODT on Eclipse 3.3... but I don't have so much time for the moment !
So I've just updated ODT website.

Thanks,

Manu

I've just passed ODT to Eclipse 3.3. This creates a compatibility break between ODT 1.1.2 and the future ODT release: those which use the next ODT release will have to use Eclipse 3.3.

I've updated the website and the plugins. The version to be used is 1.1.3.
