AEM forms designer // Cannot import XSD - too many resolved schema nodes




I hope you are able to help me.

We are investigating the use of AEM forms (previously Adobe Livecycle) to populate data in dynamic pdf forms.

When creating the data connection and importing the XSD (XML Schema), following error appears:


The schema described by the selected root element cannot be read

as the number of resolved schema nodes exceeds the supported limit.

Please select a different root element of modify your XML Schema to decrease the schema size.


Unfortunately none of these suggestions are applicable to us.

I heard that there is a limit of 100,000 nodes. This is done for memory considerations. The limitation is a resolved node count not a direct 1 to 1 node in the schema.  There is a registry setting that will allow to increase this number.

Unfortunately I haven't yet found this setting.

Could you please assist me increasing this limit?

Thanks and best regards,

Can you provide a bit more information? e.g.

  • Where are you seeing this error? Workbench? Designer?
  • How many unique nodes are actually in your schema?
  • Is your schema well formed? [1]
  • Does it contain any recursive nodes? [2]
