g:sortableColumn generates wrong links when used with a controller with a specific mapping

[fuxx]

Hej!

The issue is known since 2017 and was not merged because of a missing test.
I create a pull-request with the required tests as requested in the original pull request made to grails core grails/grails-core#10839.

Original issue: grails/grails-core#10819
Related issue:

• https://github.com/grails-fields-plugin/grails-fields/issues/303
• g:sortableColumn generates wrong links grails-core#9400

the issue was reported before, but was closed because the issue was not described properly.

Fortunately it is very straightforward ...

Steps to Reproduce

1. Create a controller with a mapping like this: "/somepath/mycontroller/$action?/$id?" controller: 'mycontroller'
2. use sortable column tag on a GSP rendered by mycontroller: <g:sortableColumn property="prop" title="Title"/>

Expected Behaviour

The generated link should be "/somepath/mycontroller/index?sort=...".

Actual Behaviour

The link misses the "/somepath" part. Wrong URL: "/mycontroller/index?sort=...".

Environment Information

• Grails Version: 3.3.0
• JDK Version: 8

Fix

As described here, replace def namespace = attrs.namespace ? attrs.remove("namespace") : "" with def namespace = attrs.remove("namespace") in org.grails.plugins.web.taglib.UrlMappingTagLib#sortableColumn

Is here anything missing, are you in holidays or are you internally discussing about this one?
What is the current status?
