@Gourav_Mukherjee, can you please check if all bundles on your server are active? Secondly, what is the AEM Forms version are you using?

@NirmalAEM , you can add the sign tags in text document fragments. When the final PDF is generated and sent to Adobe sign, it will honour the sign tags.

@Amreen1 are you designing a XDP?

@AnushaAt1 ,  In your AEM server start command you need to add the above optionjava -Djdk.xml.xpathExprGrpLimit=100 -Djdk.xml.xpathExprOpLimit=2000 <..other options..> -jar cq-quickstart.jar

@AnushaAt1 , please check the error.log file in crx-quickstart/logs folder of your AEM installation. If you see the exception specified in the origin then you are facing the same issue. You can solve this issue by setting the following JVM argument while starting AEM-Djdk.xml.xpathExprGrpLimit=100 -...

@namontemayor , you need to set this argument in JVM arguments while starting the AEM instance. 

@nileshpb you cannot edit XDP in the browser. You need to edit the XDP in AEM Forms Designer and then re-upload it to update the XDP in AEM.

@TalKe , can you please explain what do you mean by Correspondences? Which AEM Forms version you are working with?

@crich2784 What is the use case that you are working? What feature of AEM Forms you are trying to use?

@LYUAN A new version of the AEM Forms client SDK has been released. Please use the same.
