How do I set the language of Input Control?

Ok so here is my Input Control

Note that the Info in the "Course Group" (Single Select Query) is in English

Here is the Query that gets the data in "Course Group"

• select distinct(cog.cog_id) id, concat(cd.cd_shortdescription, ' (', cn.cn_shortname, ' - ', cog.cog_org_be_id, ' - ', cd_code.cd_code, ')') coursegroup
  from es_exam_statistics_ft es, cg_classgroup cg, org_organisation org, cn_campusname cn
  , cog_coursegroup cog, cd_codedescription cd, cd_code
  where es.es_cg_id = cg.cg_id
  and es.es_cog_id = cog.cog_id
  and cog.cog_coursegroup_cd_id = cd.cd_id
  and cd.cd_id = cd_code.cd_id
  and org.org_be_id = cog.cog_org_be_id
  and org.org_campusid = cn.cn_campusid
  and cg.cg_startdate >= $P{startDate}  
  and cg.cg_enddate = $P{endDate}
  and cd.cd_language_id = 3
  and cn.cn_language_id = 3
  order by coursegroup

The problem comes with the lines i have Highlighted Red
Language Id's
2 = Afrikaans
3 =English

Now as you can see, the Query is hardcoded so that the language is always english, So if a user logs in, in a different language, the data in the input control will always be English

I tried replacing the 3 with "$P{REPORT_LOCALE}.getDisplayLanguage().equals("English") ? new Integer(3): new Integer(2)"
Which works in the XML of a Report, but doesn't work in the input Controls Query

How do I solve this Issue ?
