bottominfo has  to be > 1 length set when create form:

    bottominfo: '  '   // <=== at least one space.

if zero-length, e.g.

    bottominfo: ''    // <=== zero-length string, but sets it in DOM bottominfo.  If not in initilialize, then not in DOM, then never works.

For sake of community we post our find.

Bottominfo never displays message even when successful, e.g.

afterSubmit: function(response, postdata) {
    var ss = response.responseText.split(':');

    var tf = (ss[0] == '1') ? true : false;     $('.bottominfo').text(ss[1]);                                   <== We want "Item successfully created".  How???    var newid = (ss[2] != undefined) ? ss[2] : null;     return [tf, ss[1], newid];
  }

Another page in our app DID update .bottominfo on success.

We compare the two, and found no difference other than order of setting parameters prior to display form.

Debugging in browser showed no errors of any kind, working or non-working page.

We copy working page to non-working and just have to close this.

Sorry, we cannot debug it to find out our time must go on our app.

PROBLEM: DISPLAY MESSAGE ON FORM (FORM EDITING)  IF  *SUCCESS OR FAILURE*  IN SERVER RESPONSE.

Like doc says, if afterSubmit return true, message is NOT displayed.   WHY???  We MUST have message on form for success,

Maybe jQuery selector is wrong below?  

afterSubmit: function (resp, pdata) {

    var m = resp.responseText.split(':');

    $('bottominfo').text(m[1]);  // <=== PUT MESSAGE ON FORM *REGARDLESS* OF SUCCESS/FAILURE.

    return(m[0] == 'true' ? true : false, m[1], m[2] != undefined  ? m[2] : null);  // <== RETURN MESSAGE EVEN WHEN SUCCESS, BUT NEVER DISPLAYS (AS DOC SAYS IT WILL NOT IF RETURNING TRUE....AGAIN, WHY???)

}

Thanks in advance for help.
