Dynamic Document Generator

Hi

We have updated the plugin version from 1.8.5 to 1.87. After upgrade document generation workflows are breaking with thefollowing error.

com.appiancorp.suiteapi.common.exceptions.AppianRuntimeException: com.appiancorp.suiteapi.common.exceptions.AppianException: java.lang.NoClassDefFoundError: com/lowagie/text/DocumentException

Please fix this issue as it is impacting production deployment.

Hello,

We are planning to upgrade this plugin from 1.4.1 to latest version 1.8.7. 

DOCX from XHTML smart service is working in older deployed plugin but once we deploy new version 18.7. we are getting below error:

iText.jar exist in the older version (DynamicDocumentGen-1.4.1), however, missing in newer version(dynamic-document-generator-1.8.6 & dynamic-document-generator-1.8.7), which is required for generating docx.

We tried adding iText.jar in latest 1.8.7 version and it is working. 

Any plans to add back the iText.jar back in official release of this plugin?

As per release note of 1.8.6, "Removed dependency on iText", can you pelase suggest how can we get the DOCX to XHTML working back without iText.jar? 

Looks like it's an embedded svg and <instream-foreign-object/> that is the problem.   Again, it works in apache fop just not when that code is hosted in this plugin apparently.

I've run apache fop 2.5 locally against my xsl-fo and xml and I get my pdf with an embedded svg image but using the same xsl-fo and xml using Appian and this plugin results in a generic java error "An error occurred in executing an Activity Class."  Does this plugin handle embedded images?    

Can you confirm that the XslParameter CDT is available? Is it possible that you might have deleted the CDT?

Note that as of 21.4 Smart service plug-ins now load successfully if the related CDT has the same structure, even if the CDT has a different version number (e.g. it was imported in a package or deleted and recreated)

The error will go away as long as the XslParameter CDT exists. 

Do you know why the iText library is no longer bundled with this plugin?  The missing iText library has broken the 'DOCX from XHTML with Styling' Smart Service.  Can this library be added back to this plugin like it was for version prior to 1.8.6?  We have successfully fixed the broken smart service by creating a custom version of this plugin where the only change is adding iText 2.1.7.  Additionally, we've had success with the latest version of OpenPDF (https://github.com/LibrePDF/OpenPDF) which should serve as a sufficient substitute for iText, assuming that iText was removed due to changes in it's licensing

Post upgrading to 21.4  we are getting errors during the startup of the Dynamic Document Generator Plugin. Does anyone have faced similar issues?

Hi Raza, 

We are using the Docx from XHTML service under the latest version of this plug in, and as mentioned below we are receiving the following error message in the logs:

Is there a patch for this issue?

Hi,

We have requirement for converting hebrew language DOCX Document to PDF Document.
We have tried to convert using "PDF from Single DOCX (with Fonts)" Smart Service.
But Hebrew Language content is replaced with ### symbol in created PDF Document using this smart service.
So we created constant, added two hebrew ttf document ("NotoSansHebrew-VariableFont_wdth,wght.ttf","NotoSerifHebrew-VariableFont_wdth,wght.ttf") and added as Font Documents in that Smart Service.
But still we got the same PDF document with replaced ### symbol.

Could you please suggest, what kind of font document we need to upload for hebrew language to get original Hebrew Language PDF Document?
