Looks like we have a small bug in org.talend.sdk.component.runtime.manager.configuration.ConfigurationMapper. The bug may be nondeterministic.
During the recursive handling of configuration the class incorrectly handles the level of recursive.
The current behavior is to clean all indexes of all levels when you exit the level of the array handling. Instead of that behavior it should clean only the indexes for the level that was handled and remain all above levels.
That's why when "mapper" tries to handle ${index} for the parameter that inside array (upper level) after the handling of the array parameter (inner level) "indexes" map is empty and the resolve is unsuccess.
Example:
(1)configuration.partitioning[${index}].rangePartitioning.columnName=int2Field
(2)configuration.partitioning[0].rangePartitioning.bounds[0].upperBound.bound=INCLUSIVE
The row (1) was handled after the (2) in the result "mapper" don't have information on how to substitute the "${index}".
Order of the nested parameters:
