_xx.removeInstance(0) problem

Avatar

Former Community Member

I have a form that has 9 pages,

I want to dynamically remove the 1st page by clicking a button.

so I wrap the entire 1st page in a sub-form,

flowed,

min count  0,

initial count 1.

and the _xx.removeInstance(0) is in the click event of the button.

but when I click it, the 1st page got wiped clean, it doesn't remove the page, it just make the page blank.

Is there a way to get rid of the 1st page completely?

thanks

You removed the page but you did not remove the Master Page instance....I bekieve that is what the blank page is.

Lets validate that before we go down that path. Can you put a button on your Master Page (outside the content area) and add this javascript code to the click event of the button:

app.alert(this.somExpression)

Now run your form and remove the page as before. Is the button there? If so press it and let me know what is in the dialog box.

yes the button is there. 

the popup says:  xfa[0].form[0].DD[0].#pageSet[0].Page1[0].Button2[0]

Then that prooves that the master page is still there .....not sure if ths will work or not but lets try the command:

DD.pageSet.Page1.instanceManager.removeInstance(0)

The otehr thing you can try is instead of removing the instance of your initial page try changing its presence to hidden. This shoudl hide the page and the Master page and omit them from the layout.

it's the same result, I still got a blank page.

(setting the presence to hidden also leaves a blank page, same as before)

in the Javascript console, there's a message saying "DD" is not defined... but in the form designer Hierarchy, "DD" is the root of the form.
