> I find 2 Bugs in interactive.form, And I have resolved this 2 Bug. Here are the Code
> 1.	 I want make new Textbox in pdf. It always failed because the type flag  “COSName.FT,="Tx"” never be set in the constructor. 
> The PDTextbox can only be correct initialized from COSDictionary.( That is only initialized from exist pdf file) .
> I fixed this by add “getDictionary().setName(COSName.FT, "Tx");” in the constructor of PDTextbox. 
> Maybe it’s not right place, but works in my project. 
> public PDTextbox( PDAcroForm theAcroForm )
>     {
>         super( theAcroForm );
>         getDictionary().setName(COSName.FT, "Tx");
> }
> public PDTextbox( PDAcroForm theAcroForm, COSDictionary field)
>   {
>         super( theAcroForm, field);
>         getDictionary().setName(COSName.FT, "Tx");
>   }
> 2.	Same Bug in PDAnnotationWidget. Only the default constructor initialize the type flag  “COSName.SUBTYPE,= "Widget"”. 
> But the default constructor were never be used. So I must use the PDAnnotationWidget to initialize the new PDTextbox, like blow.
> PDAnnotationWidget Widget = new PDAnnotationWidget();
> PDTextbox textBox = new PDTextbox(acroForm,Widget.getDictionary());
> Otherwise I got an empty  PDAnnotationWidget from PDTextbox .getWidget().
> Something not correct in PDField .getWidget(). 
> If the the PDField create from user(not read from exist pdf file), the getWidget cannot get an correct initialized PDAnnotationWidget. The COSName.SUBTYPE will never be set.
> Maybe the similar Bug in the whole org.apache.pdfbox.pdmodel.interactive.form: the COSDictionary  of element are not initialized when user create it manually (Typical to insert new acroform  element).
> I hope  that I can give  something help  to this opensource Project.
> Could you check this and fix in next Version?
