from = 1 to = #ArrayLen(cfcatch.tagContext)#>
<cfset sCurrent = #cfcatch.tagContext[i]#>
<br>#i#

Example2
The following example shows how to throw an exception from a component method:
<cfcomponent>
<cffunction name="getEmp">
<cfargument name="lastName" required="yes">
<cfquery name="empQuery" datasource="cfdocexamples" >
SELECT LASTNAME, FIRSTNAME, EMAIL
FROM
tblEmployees
WHERE LASTNAME LIKE '#arguments.lastName#'
</cfquery>
<cfif empQuery.recordcount LT 1>
<cfthrow
type="noQueryResult"
message="No results were found. Please try again.">
<cfelse>
<cfreturn empQuery>
</cfif>
</cffunction>
</cfcomponent>
