form validation with onsubmit and js

Hello,

I'm trying to integrate a javascript file with a validation function with the ui-lib functions that generate forms. To do so i create my interface as follows:

    [snip]
    use WebminCore;
 
    my $js = "<script type='text/javascript' src='/virtualmin-myextension/validate.js' ></script>\n";
 
    print header("Mailboxes Configuration", null, undef, undef,0,0,undef, $js);
 
    [snip]
 
    print ui_form_start("","post",undef,
        "onSubmit=\"return check_form_valid()\");

the mailbox.js content is:

    function check_form_valid()
    {
        alert("hello");
        return false;
    }

the produced HTML code is like this:

    <head>
    [snip]
    <script type='text/javascript' src='/virtualmin-myextension/validate.js' ></script>
    [snip]
    </head>
    <body ...>
    [snip]
    <form class='ui_form' action='' method=post onSubmit="return check_form_valid()">

apparently the form validation does not happen (no alert is executed). on the contrary, if I build the form as: print ui_form_start("","post",undef, "onSubmit=\"return alert('something')\");

i can see the alert popup.

the js path seems to be correct, because in firefox i can see the source file and double click in the "src" link of the element "<script src="/virtualmin-myextension/validate.js' >" and it loads the correct file.

is it possible I'm missing something?

thanks in advance
