Dynamic Document Generator

Hi Raza Mir(Author)

We are having issues with this plugin when generating a PDF doc form DOCX. This plugin is working whit out any issues until 21.2 Version. We recently upgraded one environment to Appian latest version 21.3. After this upgrade the PDF from Single DOCX (with Fonts) smart service is breaking when generating  document. The same DOCX document we will be able to convert in other environments(21.2). We are not sure what is the root cause. I see based on the documentation it supports until 20.4. Could you please update this plugin to support the latest versions. 

The following is the log error from the tomcat-stdOut.log

• Removed dependency on iText

Raza, we attempted to upgrade the plugin tot he newest version about 3 weeks ago and got the errors indicated in the below message.  We needed to have Appian revert our version back to the old version because we could not get the new version to work without an error.  Can you please respond to let us know if we have something configuring incorrectly or if you have a fix for the error.

We even had Appian increase the timeout hoping that would help evaluate the error but we still had the issue.

Thank you

We are using this plugin and the PDF from HTML smart service and are getting a timeout error and the PDFs are not getting created.  This has been working for at least a month and is now failing in all environments and just started yesterday.

This is part of the log error from the tomcat-stdOut.log

ERROR com.appiancorp.ps.xmlfo.ss.PdfFromHtml - The PDF generation took longer than 10 seconds

We are using this plug in and the PDF from HTML smart service and started receiving errors yesterday and today.  It has been working for at least a month and just started failing in all environments today.  Here is a section of our tomcar-stdOut.log. It does appear that  it is a timeout issue, there are 2 in about 100 that do get converted.

in addition to the above i am passing multiple font documents also

Hi Michael Chirlin  need some help. I am using this smart service to generate PDF in Arabic  language., For that I am using pdf from docx with fonts. I see that arabic characters are displayed as #### etc.  We are going with an approach like docx templates are created by client and Appian should  generate docx based on the given template and convert it to PDF.  Is there any other way that can be used to generate pdf in Arabic language/ utf-8 support

Hello.

I've deployed the plug-in, but cannot find the "DOCX from XHTML With Styling" smart service with in the process modeler.

How can I use the "DOCX from XHTML With Styling" smart service? Need Help ASAP.

Thanks
