Hi,

Is there a way to check if a form is already loaded or not ?

Regards,

2

shouldn’t that be in History?

3 
if ("formName" in forms) {

}

but that would be true for any form in the solution, loaded or not, no?

if it helps you: the onShow event of a form has a boolean that indicates whether or not it’s the first time show after a load.

Don’t know if this information is too late for you (code-wise)

you’re right Patrick.

The code from Paul always returns true if the form exists.
It does not look at the “loaded state”

7

but it should be in the history stack…

Close,

The current form is loaded, but it is not in history,
but I can add that to my own check.

Thanks Patrick.

That code snippet I posted checks the forms array, which contains the actually loaded forms. If you want the full list of forms, you have to go through forms.allnames.

Note: the forms array is special, in the way that when you would do forms.nameOfNotYetLoadedForm, it automatically starts loading the previously not loaded form.

Hi Paul,

Has something changed ?

if (_inForm in forms)

Now returns forms that the user has not visited yet.

This is in 5.2.15

Hi Hans,

No, nothing should have changed. I haven’t tested this in 5.2.x, but in 7.x it still works as advertised.

I can’t realy believe it would’ve stopped working though. Are you sure you’re testing it ok?

Paul,

Thanks !
Will do some more testing and I’ll get back on this.
