When using a formatted field with a text character, the user looses the typed-in
text then tabbing *OUT* of the formatted field box.

Here are the detailed steps to reproduce:
Start OO.o
File | New | XML Form Document (although problem exists in Text Document also)
View | Toolbars | Form Controls (toggle this toolbar to be viewable)
From the form controls toolbar, select Textbox and place it somewhere in the
document
From the form controls toolbar, select Formatted field and place it somewhere in
the document
Double click the formatted field to bring up the "Properties: Formatted Field"
window
To the right of the "Formatting" box is an ellipses button that you click to
bring up the "Number Format" window
In the "Categories" section of the "Number Format" window, click "User Defined"
In the "Format Code" section, type a valid code such as your help document
states: "#.# \m"
Add this custom format to the available list by clicking the Add checkmark.
Click the "OK" button in the "Number Format" window which brings you back to the
"Properties: Formatted Field" window
Close the "Properties: Formatted Field" by clicking on the X in the window
decoration
Toggle design mode off using the form controls toolbar
Type the number "1" in the text box
Press the tab keyboard button to move the focus into the formatted field box and
type "1"
Press the tab again which moves the cursor back into the text box.
Press tab a few more times and you will notice my "1. m" in my formatted field
box changes to ". m" simply by pressing tab a few times.

Comments:
I know the format specified #.# and I only typed a "1" but my "1" should never
disappear.  If I strictly obey the format rule and instead of typing "1" I
should type "1.1" into the formatted field, then the problem is not seen.  The
issue is not my typing "1" versus "1.1" but the tab key changing the values of
the field.
