XML editor throws error

[ertnutler]

When I open a pom.xml file in STS 2.2.1, it throws an error. Anybody seen or worked around this?

Hi,

can you please send over your complete error log?. The stacktrace you pasted is usually an follow-up error on something else during initialization.

Also please try again with a Sun JDK.

Hi,

I've got similar problems on my windows box with STS. I tried to integrate STS into an existing eclipse galileo installation but also to install a new full STS distribution (via zip-file and via installer). With every setup, I've experienced the same problems: every time i try to open an XML file an error box pops up (org/springframework/ide/eclipse/core/SpringCoreUtils) and then the pop up appears on nearly every click.

Plattform: Win XP, Sun JDK (1.5.0_14 and 1.5.0_15)

The error log contains a lot of NoClassDefFoundErrors which are mainly caused by a ClassCastException (see attached log file).

To work with grails projects, i had to set the GRAILS_HOME variable explicitely.
Otherwise I assume it would work, if I wouldn't get these error pop ups upon nearly every click.

I tried the same also on Mac OSX with the cocoa installer distribution and everything worked fine even without having to set the GRAILS_HOME variable explicitely.

Thanks in advance.

Tom,

I just yesterday fixed - or better implemented a work-around - for your problem. It is released to trunk and can be installed from the nightly update site.

Please update your copy of STS/Spring IDE from http://dist.springframework.org/snapshot/IDE/nightly

Please let me know if that fixes your issue.

Christian

Hi Christian,

I've just performed an update and this looks much better now. Thanks a lot for fixing and pointing me at the update!

Working with the suite including grails projects seems to work without problems.

The only difference to the OSX installation I discovered so far was the short cut for the grails console (CTRL+ALT+G) which does not work. As I saw in the log, there is a key binding conflict, but I can deal with this by myself.

Anyway, thanks for improving grails development that much.

Tom

Tom,

thanks for verifying that the change fixes the issue that you were seeing.

I'm aware of the key binding conflict. I haven't changed the binding yet because I simply can't find any good and non-conflicting combination. Any ideas?

Christian

[tom-01]

Christian,

sorry for the late reply. I see your trouble. The amount of already defined bindings is huge.

One combination, though not especially convenient, is Ctrl+Alt+Shift+G. At least this would keep realtion to 'G' for 'Grails' which definitely makes sense.

Regards,
tom

tom,

CTRL-SHIFT-ALT-G is what I went with now. Thanks for the suggestion.
