Issue with autosuggest on a numeric field

Question

I have a form with a CFINPUT that has autosuggest to a cfc.
The cfc runs a query against a varchar field that has only numeric
values. When the match is made and the lis is returned I get an
error (Bind failed for autosuggest CUSTOMER, bind value is not a 1D
array of strings). This only happens with fields that are all
numeric, if the field has any letters or symbols I do not have this
issue.
The data returned is coming back as numeric in scientific
notation (CFC invocation response: [5.159000038E9]) The data is
matching on the phone number and that is what is being returned.
It there a way to correct this issue? Code sample is below.
<cfinput type="text" name="CUSTOMER" size="10"
maxlength="10" value="#CUSTOMER#"
autosuggest="cfc:customerInfo.getCustomerSuggest({DSN},
{cfautosuggestvalue})">
here is the function from the CFC:
<cffunction name="getCustomerSuggest" access="remote"
returntype="array" output="false">
<cfargument name="argDB" type="string" required="yes">
<cfargument name="argCUSTOMER" type="string"
required="yes">
<cfset var myarray = ArrayNew(1)>
<cfquery name="cstInfo" datasource="#argDB#"
maxrows="25">
SELECT customer
FROM custFile
WHERE customer LIKE <cfqueryparam value="#argCUSTOMER#%"
cfsqltype="CF_SQL_VARCHAR">
</cfquery>
<cfloop query="cstInfo">
<cfset arrayAppend(myarray, '#customer# ')>
</cfloop>
<cfreturn myarray>
</cffunction>

Answer 1

I don't understand the actual results desired. But I would
make my cffunction returntype a string and get rid of the cfloop
that creates your array. One of my autosuggest cfcs is;
<cffunction name="getJobsearch" access="remote"
returnType="string" output="false">
<cfargument name="term" type="string"
required="false">
<cfset var Jqry = "">
<cfquery name="Jqry" datasource="taxsearchdb">
SELECT J.CompanyName + ' ' + J.CompanyCity + ' ' + C.State +
' ^' + cast(J.JobOrderNumber as varchar) as Jname
FROM jorder J, Companies C
WHERE J.CompanyNumber = C.CompanyRecordNumber and
J.CompanyName LIKE <cfqueryparam cfsqltype="cf_sql_var"
value="#trim(arguments.term)#%">
</cfquery>
<cfreturn ValueList(Jqry.Jname)>
</cffunction>
