I am running into the same problem and need urgent help on this matter. I've been through these documents already and they are of no use. Do you have any solution to resolve the problem? How can we set the language otherwise?

I did find a solution. I'm currently using Adobe LiveCycle Designer ES 8.2 as an FYI.
(1) Create a blank form
(2) Pull over the "TEXT" Box
(3) Your "Layout" & "Object" tabs should appear on the right of your screen.
(4) In the "Object" tab, under Locale, click on the drop down box and select "English (USA)". I know it automatically defaults to it underneath, but you have to physically place it in the box.
I have found you have to do this for every item you put on your form whether it's a check box, Numeric Field, everything. If you have Adobe Pro 9 like me, a way to make sure you correctly placed the "English (USA)" in all the boxes, in Adobe Pro, complete the following steps:
Click on "Advanced" from the menu bar
It will run a full check to ensure your form is Section 508 compliant. Hope this helps.
