Datagroup content listing to a html page with an iRule

Hi,

I was wondering if anyone has an idea why my datagroup content listing page made with an iRule broke when customers services were moved from a big ip platform running version 11.6.1 to 12.1.2 HF1. The setup was moved from /common to a customer specific /customer1 partition. Could this have any impact why this is not working? Should there be some pointer to the partition?

Here is the iRule with namings modified:

when HTTP_REQUEST {

if { ([IP::client_addr] equals "1.2.3.4" ) and ([HTTP::uri] starts_with "/lista/") } {
    set listaurl [string range [HTTP::uri] 7 end]
    set lista customer1_$listaurl
    if { [class exists $lista] } {
    set response "Customer 1 datagroup list - [clock format [clock seconds]]
" 
    set response "$response [class names $lista]"
    set response "$response 
"
    HTTP::respond 200 content $response "Content-Type" "text/html"
    }
    else {
        set response "Customer 1 datagroup list - [clock format [clock seconds]]
" 
        set response "Non existent datagroup name"
        set response "$response 
"
        HTTP::respond 200 content $response "Content-Type" "text/html"
    }
}

}

Any help is greatly appreciated!
