Dynamic Document Generator

Hi Raza

We are using the Appian version 21.3 and we have trouble converting DOCX and HTML to PDF when it contains Greek characters. They just appear like this ########. Is there a solution to that?

Hi Raza.mir,

We are using plugin version 1.8.6, where we encountered issue with smart service "DOCX from XHTML", this smart service is failing with below error. When i checked node duration it is almost running for 4 and half days.

"The amount of time allocated for the completion of an unattended activity was insufficient to allow the activity to complete."

FYI - Appian version - 21.2

The older version works as expected(1.8.2), could you please look into this.

Thanks

Raza Mir do you have any plans to update this plugin. We are waiting for your response.

FYI - PDF from EML doesn't seem to work. Based on the error and googling it seems like some sort of jar conflict, but I'm not too sure.

Any Update Raza Mir

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
