Grails: g:link not applying params with dynamic/GString keys

I'm trying to create a link with a dynamic link like: 

<g:link action="${nextDashboardUriMap.nextAction}" params="${["$nextDashboardUriMap.queryStringId": "$entityId" ]}">
        ${entityName}
</g:link>

where nextDashboardUriMap.queryStringId contains xyz and entityId contains 12.

I was expecting url of the link to be http://website.com/controller/action?xyz=18 but <g:link/> consistently gives me http://website.com/controller/action?xyz.

I have tried replacing entityId with a string literal.

You don't need to use GStrings here, you can simply say

<g:link action="${nextDashboardUriMap.nextAction}"
        params="[(nextDashboardUriMap.queryStringId):entityId]">

It seems that it may be this bug: GRAILS-9774 - the value is lost if key in params map is of type GString. Converting the key to String should resolve your problem:

<g:link action="${nextDashboardUriMap.nextAction}"
params="${[("$nextDashboardUriMap.queryStringId".toString()): "$entityId" ]}">
(...)

how about

<%
     Map paramsMap = [:]
     paramsMap[nextDashboardUriMap.queryStringId] = entityId
%>
<g:link action="${nextDashboardUriMap.nextAction}" params="${paramsMap}" >${entityName}
</g:link>
