DHTMLXCONNECTORS is undefined in a Java object

Suite 7.0/6.0/5.0 and Optimus Suite 5.0
#1

I define in Coldfusion Server Settings > Mappings the “DHTMLXCONNECTORS” and their folder of connector.

I restarted the application server, but when I run the next code:

Documento sin título 
<cfset tree = createObject("component",request.dhtmlxConnectors["treegrid"]).init(request.dhtmlxConnectors["#datasource#"],request.dhtmlxConnectors["MySQL"])>
<cfset tree.render_table("indice_edicion","pk_indice_edicion","indicador","","fk_indice_edicion")>

And I get the Next error:

Element DHTMLXCONNECTORS is undefined in a Java object of type class [Ljava.lang.String;.

Thank you.
