Invisible fields and nothing saved

I've been doing some work on the Webform Integration recently. If you would try out the dev version of Form Builder, you'll probably have much better results.

I'm running the dev version of form builder and I am running into a similar issue. I tried adding a hidden field and named it, but when I hit save nothing was there. If I bring the hidden field and place it, then hit save with the defaults, then go back and edit it, it seems to avoid this issue. However I then went to move the field up one position, above the other hidden field I had, then saved it, both of the hidden fields disappeared, and thetype of every precededing field got shifted. So if I had:

element 1 - hidden
element 2 - hidden
element 3 - grid
element 4 - textarea
element 5 - radio

After I tried moving element 2 to position one, both of the hidden elements (1 and 2) are now gone and my structure looks like:

element 3 - hidden
element 4 - grid
element 5 - textarea

So it seems like something is wrong with the save functionality with Form Builder and it's Webform integration.

I’m seeing a similar problem. I noticed in my case that fields only disappear when I give them a custom form key.

For example:

1. Add some radios, give them a form key
2. Add a second set of radios, give that a form key
3. Save, the first set of radios is gone.

I am also having troubles saving the form fields. Guess I will have to do it the old school way. This module is a great idea though.

I am experiencing the same issue. However when I turn off the form builder webform module and add a field to the same mode the core webform way, all the other fields appear back in the list under the "new component" row.

I still can't reproduce this issue. I'll need instructions on how to reproduce this problem from a clean install of Drupal.
