IW 15.5.5 PerformAfterAsyncProcessing(); formClass is not defined - ebob42 - 01-11-2024
With IntraWeb 15.5.4 (and .5) for an ISAPI.DLL we sometimes get a JavaScript console error (in FireFox F12) that says:
Error in processAjaxExecute when evaluating: PerformAfterAsyncProcessing(); formClass is not defined
The error can be trace to the IWBase_xxxx.js file.
This does not happen with IntraWeb 15.4.2. Any idea? We haven't changed anything else.
Note that it looks like everything on the page itself is still working, but I want to ensure everything is fine before we deploy this version.
Thanks in advance!
Groetjes, Bob Swart

Hi Dr. Bob,
I'll have a look. Did you ever get it in SA mode while debugging/developing?
Cheers

PerformAfterAsyncProcessing() is not a method part of IntraWeb codebase. Is this your parts of your own code or 3rd parties?
RE: IW 15.5.5 PerformAfterAsyncProcessing(); formClass is not defined - ebob42 - 01-12-2024
PerformAfterAsyncProcessing() is a JavaScript function of our own, it is called in the DoGenerateForm of our main base form (derived from TIWAppForm, and the parent for all our other intraweb forms.
Code:
procedure TIWCaiwBaseForm.DoGenerateForm(AStream: TIWRenderStream);
begin
inherited;
if WebApplication.IsCallBack then
WebApplication.CallBackResponse.AddJavaScriptToExecuteAsCDATA('PerformAfterAsyncProcessing();'#10);
end;If looks like the above JavaScript is now added before the formClass value itself is present.
'formClass' is a javascript variabele which is set in our $(document).ready( ) function, based on the value of IW_FormClass.
Code:
formClass = $("input[name=IW_FormClass]").val()IWForm.pas sends the IW_FormClass to the browser (line 821) in procedure TIWForm.DoGenerateForm:
Code:
Contents.AddHiddenField('IW_FormClass', Self.ClassName);So my guess is that AddJavaScriptToExecuteAsCDATA may end up in the resulting page in a slightly different order using IW 15.5.x compared to IW 15.4.2 ??

I'll try to simulate it here and see how it goes.

Hi again Dr. Bob,
I'm having a little trouble recreating it... more specifically, how to you trigger the DoGenerateForm() on Async? Do you force a reload or any other specific action? Are you swiching forms?
RE: IW 15.5.5 PerformAfterAsyncProcessing(); formClass is not defined - ebob42 - 01-16-2024
I see the message when we enter a new page, as soon as that page is being loaded (which almost sounds like an Async event is happening at that time, I'lll see if I can figure this out on our end as well - but like I said, the same applications runs without this message using IW 15.4.2).
RE: IW 15.5.5 PerformAfterAsyncProcessing(); formClass is not defined - ebob42 - 01-17-2024
We seem to have solved it on our end by adding some more code to the DoGenerateForm using AddToInitProd, sorry to waste your time on this.
