Proposed patch: fix the Tag Library template registration id.

The template implementation for the groovy plugin expects the taglibrary template id to be 'TagLib':
http://hg.netbeans.org/main-silver/file/6b5ae20e6f7a/groovy.grailsproject/src/org/netbeans/modules/groovy/grailsproject/ui/TemplatesImpl.java#l70

However, the template was being registered as 'TagLibrary':
http://hg.netbeans.org/main-silver/file/6b5ae20e6f7a/groovy.grailsproject/src/org/netbeans/modules/groovy/grailsproject/ui/wizards/GrailsTemplates.java#l116

This patch fixes the registration id and changes the displayName label to the same value to maintain coherency.

Jiri: I'm adding you as CC so this can be integrated if you find that the proposed patch is OK.

Comment 4 Jiri Kovalsky 2015-09-23 21:30:51 UTC

I think the patch is safe hence I integrated it as http://hg.netbeans.org/core-main/rev/c7b7e5dd5c18. Thanks for the contribution Bruno!

Comment 5 Quality Engineering 2015-09-25 01:46:55 UTC

Integrated into 'main-silver', will be available in build *201509250002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
