Please, need to solve this error "...it's not allowed in AJAX request or JS handler"

[Luis Devis]

Hi (again 😅

Ramdomly I get this message when running my application. 

... <br/>is refering a previous request,<br/>it's not allowed in AJAX request or JS handler.<br/>Use equivalent Public Property or Method instead.

No idea why this happens and even less on how to solve it.
I guess it is a common error for newbies like me so, please, don't ask me too technical questions as, probably, I will not be able to answer them.

No idea on what I'm doing wrong (not having done)

Thank so much for your help 🙂

Hello,

Perhaps because this "erroneous" code is not executed every time. The logic of your application implies this. 

Are you using JSInterface methods?

[Luis Devis]

Yes, but they should be called very time.

Is there a way to know which object or call causes the error in this line?

01:35:39.727||||[SERVER] Config Option: O310->cls:"unselectable"<br/>is refering a previous request,<br/>it's not allowed in AJAX request or JS handler.<br/>Use equivalent Public Property or Method instead. unit:System.SysUtils

 

The matter is : Why does it say is refering a previous request,? I got it at the very first moment

Where exactly?

[Luis Devis]

Internally by program , via calls to JSInterface.JSAssign(....

JSInterface.JSAssign

Can you try to use JSInterface.JSProperty ?

[Luis Devis]

I could if I know what to put in it 😅

Currently I apply these settings

pTitulo.JSInterface.JSCall('addCls', ['.myAlDerecha']);
lMarchar.JSInterface.JSCall('addCls', ['.myAlAbajo']);
Grid.JSInterface.JSConfig('bufferedRenderer', [False]);
SaldoPdte.JSInterface.JSCall('addCls', ['unselectable']);
bSaldoPdte.JSInterface.JSCall('addCls', ['borderedondo_5']);
bSaldoPdte.JSInterface.JSAssign('originalBGColor', [uniColor2Web(color)]
JSInterface.JSConfig('inputType', ['number']);

[Luis Devis]

All these calls are in the Main form (not module)

[Luis Devis]

anyway, I'm concerned on the part that say Config Option; O107->tabConfig: {id:"O107_id_tab"}
Is there a way to know what object/control is it talking about so I could check it directly?

In which event?

[Luis Devis]

After on create

 

[Sherzod]

procedure TMainForm.UniFormCreate(Sender: TObject);
begin
  // here? 
end;

 

[Luis Devis]

Yes

[Luis Devis]

Sherzod

Don`t know why but the Main form is created twice, I have the Mainform and a loginform.

All the errors happen just after FormCreate has been processed, no other event but the message happens

[Sherzod]

Hello, 

Can you make a simple testcase to reproduce? 

[Luis Devis]

Actually, no. Because don't know what put in it.
I should send the whole app as I don't know the origin of the problem. It seems that the modules are loaded (created) twice, but I do not call or create them

Maybe a simple test case would not make the error/message come up.

Hello,

There were no errors before, is this after the update or?

[picyka]

It's an old error, I can't say since when, it sleeps and sometimes appears, but I have no clue what could cause it.

[TobiS]

i got the same error sometimes. It appears when a form is opened and only for some users. Its not always the same user.

In the form i only shows a pdf file, that was created. Anyone found a working solution or even the source for this error?
