Title: RE: [iText-questions] AroFields

The PDF is correct. A field may have several dictionaries with a parent-child relationship. The merged dictionary has all the fields that are valid for that particular widget. This dictionary is read-only, changes made to it won't go into the document. The flags can and should be put in the widget dictionary.

If it doesn't work, provide a small field example with this pdf.

Best Regards,

Paulo Soares

Thanks for the reply Paulo.

I have one more question. When I try and compare�merged and widget (see code below) they dont seem to match. (see Output below). A lot of the fields does not apperar in the widget and when i try and set the pdf as read-only the fields that doesn't appear in widget aren't set to read-only. I'm attatching the pdf if you want to look at it. Is it corrupt or not up to the PDFReference? I understand that just because a pdf is shown properly in acrobat doesn't mean it is as it should be... We get the pdfs from a third party so i can't have any influence on them more than delete and remake the problemfields ;-(

thanks for any help. The project is supposed to be finished tomorrow.....

Best regards

/Martin

Get the flags value from the merged array and set it in the widget.

I'm having trouble with setting Formfields as non scrollable and/or read only. I have an existing pdf with some formfields (multiline and singleline) that I want to set as non scrolable and if the pdf is marked as signed as read only as well. In the pdf (attached) the first multiline-field on the top left, with no borders around it (field-name=501),�is treated correctly but the second one on the top right (field-name=5)�is not. There are two more multilinefields further down the doc�(field-names=6 and 10) are that's�not working correctly either.�Does anyone have a clue?. Is the original pdf corrupt or am I doing something wrong here? (code below)

thanks for any help
