How to build a column containing a list of project components

Introduction

How to create a list column containing only the components of the containing issue project.

Solution

^{Assume you are creating a grid which contains a component column. This column should list all the}
^{components of the project which contains the surrounding issue.}

^{The configuration you can use is as follows}

col.icomponent=Component
col.icomponent.name=component
col.icomponent.type=list
col.icomponent.query=select cname, id from component c inner join project p on c.project = p.id on  where p.key = {0}
col.icomponent.query.parameters = project:key
col.icomponent.query.ds=jira
col.icomponent.required=true
col.icomponent.autocomplete=true
col.icomponent.width= 75

The project.key is initialized to the value of the project key of the contaiining issue.
This value is injected into the query using the col.icomponent.query.parameters parameter.
