GSP Editor NullPointerException

[onato]

The GSP editor has been broken ever since I updated last week. I have updated every day since hoping that the problem would be fixed but alas.

Here is my error...

Could not open the editor: Editor could not be initialized.

[Andrew Eisenberg]

@Schmettermann,

It looks like you are trying to open a gsp file in a non-Grails project. Is that right? This is something that we should be accounting for, but currently throws an exception.

[Andrew Eisenberg]

@onato,

It looks like your "grails-app/taglib" folder is not on the classpath. I can't be sure that's what it is and it does seem kind of odd since it should be on the classpath by default. Regardless, an NPE should not be thrown here. I will make a change so that the problem is handled gracefully with a log entry added to the error log.

[Andrew Eisenberg]

I will add both of these fixes to tonight's nightly build. Please try this out and let me know if it fixes your problem.

[Schmettermann]

Thanks Andrew!

You were right! In the Package Explorer I opened the context menue and clicked "Configure" | "Convert to Grails-Project". After that my GSP files were displayed perfectly! Thanks a lot!

Best regards from Berlin, Germany
