Auto Complete Item Field Freezes: Unable to Handle Large Data Input

    Asked on March 06, 2013 at 09:49 AM

    Hi there,

    I am having trouble when feeding the auto-fill field with more than 61,500 characters (UTF-8) - yes, it's quite a long list ;-)

    When leaving edit mode via clicking "my forms", then wanting to re-edit the form -

    the auto-fill field and every field below disappear.

    As long as I stay in edit mode - everything works fine - I can test and even fill out the form using the auto-fill function.

    Do you have any idea how to fix that? Do I do something wrong?

    Can you please try to clear your browser cache and I will clear your form cache in our end.

    Hi, I just cleared my Firefox cache. Boxes are still gone.


    I hope this is it since I tried before and the boxes were gone.

    It seemed that leaving the edit mode via "my forms" had a different effect on the auto-fill field than "save" in edit mode. Does that help?

    Can you please post the form link or form ID you are encountering this issue or does it happen to all of your forms?

    Hi there, I created two forms with 10-digit numbers in it:

    Please type in "1" to see all available auto-fill entries when scrolling down

    Running (all entries in place):

    Not Running (auto-fill entries disappear when exceeding 59560 characters) :

    What I found out so far: The one running has not been left via "my forms" yet and was just saved in edit mode (tab still open on my Firefox). When I close the tab reopen and try to edit the form it will get broken. So currently I cannot re-edit it once I closed the tab or my session runs out of time.

    Would love to get this fixed ;-) Thanks so far, Jan

    After testing, it seems that our Auto Complete field can not handle such large number of choices. I have tested on my end and it seems to freeze with such high number of choices.

    Is there any way that you can break down the options into more then one field?

    Hi, well I've tried to think about that but unfortunately I don't see a way.

    Users should enter a string that comes to their mind and the auto-fill function shows them the needed ID of a catalog. Like this...

    User Input:



    Hello my friend by Lonely Character (ID 765432)

    Hello my guest by Dark Nights (ID 666543)

    I was also able to replicate the same issue and have forwarded it our developers for further investigation.

    Since auto-fill works using javascript on the client side it is not possible to feed large number of items to it. We do not plan on re-implementing it at this point.
