You can import Microsoft InfoPath files (XSN) into LiveCycle Designer ES. During the conversion process, LiveCycle Designer ES extracts these components from the input file and uses them to create LiveCycle Designer ES XML elements:
LiveCycle Designer ES displays the file import options each time you import an InfoPath file.
If you want to be prompted for a view, select the Prompt To Select View During Conversion option. If the InfoPath file has only one view, a prompt will not display even if you select this option.
Note:
If you select the Import Print Settings option, the page size and orientation are taken from the InfoPath form and you do not have to select the page size and orientation.
Note:
LiveCycle Designer ES uses Microsoft Internet Explorer 5.0 or later to transfer data while importing an InfoPath file. If you do not have Internet Explorer installed, you cannot import an InfoPath file into LiveCycle Designer ES.
