linq - itext XFA: InvalidCastException -


using itext7 , when trying load xfa form i'm getting:

system.invalidcastexception: 'unable cast object of type 'system.xml.linq.xtext' type 'system.xml.linq.xelement'.'

source code:

var pdfreader = new pdfreader(package.pdftemplate); pdfreader.setunethicalreading(true); using (var document = new pdfdocument(pdfreader, new pdfwriter(writems))) {     var acroform = pdfacroform.getacroform(document, true);     var xfa = acroform.getxfaform();     var dataxml = _datagenerator.generatexfaformdata(package);     xfa.fillxfaform(dataxml);     xfa.write(document); }

the exception thrown on line

var acroform = pdfacroform.getacroform(document, true);

sample pdf can seen here: https://programmcze-my.sharepoint.com/personal/nechanicky_programmcze_onmicrosoft_com/_layouts/15/guestaccess.aspx?docid=0c18710068a124a58a32e77ad53c4cbb9&authkey=aqvvbzlxnirrisljvt083xy

there indeed problem constructing xfaform not contain <xfa:datasets> entry.

the problem fixed in itext 7.0.5-snapshot version. repository sources , fix can found here.
