Potentially embed app in PowerChart

[jmandel]

Need to assess whether this works because I haven't seen the approach documented, but in:
https://github.com/chb/smart_grails_proxy/blob/master/mpage/chb_smart_launch_bpcentiles.prg

Try replacing:

    row +1 "    APPLINK(100, "
    row +1 "        grails_proxy_url + "
    row +1 "        'initial_app='+initial_app + "
    row +1 "        '&record_id=' + record_id + "
    row +1 "        '&encounter_id=' + encounter_id + "
    row +1 "        '&cas_token=' + cas_token,"
    row +1 "        ''"
    row +1 "    );"

with:

    row +1 "    var redirect_to = grails_proxy_url + "
    row +1 "        'initial_app='+initial_app + "
    row +1 "        '&record_id=' + record_id + "
    row +1 "        '&encounter_id=' + encounter_id + "
    row +1 "        '&cas_token=' + cas_token; "

followed by one of:

    row +1 "    window.location = redirect_to;  "

    row +1 "     CCLNEWSESSIONWINDOW(redirect_to,  '_self', '', 1, 0);  "
