Extend Features in Adobe Reader

[yoyo112673]

Hello,

I'm working on a form that has several dropdown lists fields wrapped individually into hidden subforms which become available (visible) once their assigned check boxes are selected. After testing the form, all works just fine. However, the issue I'm running into is actually coming up only after I Extend Features in Adobe Reader. The issue has to do with the dropdown items, in which I'm using a for loop to display my list of items very much in the same way as the "Purchase Order" form that comes with Adobe LiveCycle. The problem is that before extending the features in Adobe Reader, the dropdown list shows all my items populated in my for loop just as planned, however, once I extend the feature in Reader, all the list items appear twice i.e. item1, item2, item3, then, item1, item2, item3 again as if it "shadows" all the items.

When I noticed the issued in my form, I thought I had done something wrong, but after double checking I confirmed that the issued only occurred on the extended file and not on the original file. So, I decided to test it on the "Purchase Order" form by "Extending Features in Adobe Reader" and and the same thing occurred to the "Part No." items. You can check it out for yourselves!!

I'd appreciate any help you can give me to solve this issue.

Thank you!!

Hi,

If you look here you will see that some events "appear" to fire twice when the form is enabled: Event fired twice

I suspect that you have the script in an event like docReady or initialize.

You could move the script to the preOpen event of the dropdown. This fires just as the user is opening the dropdown.

Another possible solution would be to include the following line at the very top of your populating script for the dropdown:

this.clearItems(); 

This would clear the list when the event fires the second time in the Reader Enabled form and then just populate it again once.

Good luck,

Niall

Niall,

I actually have my script in the "change" event, and it reads "FruitsScript.getFood(xfa.event.newText, LabelSheets".

I moved it to the "preOpen" event and not only the event keeps firing twice, but I also don't get the second array to display anymore. (LabelSheets).

This is sort of what I have in my actual form. It is a table that expanded in which header 1 would be my items, and header 2 would display the value assigned in the second array.

Header 1	Header 2
Dropdown List (keeps Firing Twice)	"LabelSheets" (does not display value)

Thank you for your help, I really appreciate it!!!!!!

I forgot to mention. if I use the "this.clearItems();"  script; once I select one item from the dropdown list, it freezes it and I cannot open the list anymore.

Thank you!!!

Niall,

I spoke too soon. I changed my script to the preOpen event and now it creates a “shadow” list for every time I select an item on the list. So, the first time the list shows the original items, then, if I choose a different item, the list now displays twice as many, and then, if I choose a different item, then the list fires another set of items, and it keeps on growing….

I really appreciate your help!!!

Niall,

Please disregard the last two messages. The script "this.clearItems();" totally resolved the problem I was having with my form.

Thanks a LOT!!!!!
