Issue Summary

Insight Confluence Macro configuration breaks when source schema has too many attributes

Steps to Reproduce

1. Create an object schema with huge amount of object types and many attributes for each object type.
2. In Confluence attempt to add the Insight Macro, configure it to target the above object schema and one of the object type.
3. Select at least one object (the bug is reproducible disregarding the number of objects selected in this step):
   
4. Clic on Next and observe that the page hang with no way to cancel the operation. browser just crash. It is expected to get here the ‘Select Attributes’ screen as next and the bug it is mainly related to all the attributes found in the schema because in this screen we do present a “tree” of all object types with their attributes.

The server is sending all this data correctly but it is the UI that have problem parsing it.

By looking at the HAR file we observe a huge waiting time in fact.

Note that it also happen with 1.6.6 and 1.6.1 versions.

Expected Results

The Select Attributes page need to appear in order to complete the Macro configuration.

Actual Results

The page hang with no response.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
