Issue
Exponare is running fine. But event logs have large number of warnings "A databind named XYZ has already been added to this layer ABC."

Cause
In an Exponare work-context, assume a layer has data-bind named "DB". If a global layer group is added to that work-context and a layer in that global group has a data-bind of same name "DB", then this warning is written to the log. Essentially, it is saying a data-bind of that name already exists for this layer. This is not a bug, but the intended design in order to help catch duplicate data-binds.
An example in Exponare sample data:
- Global layer "ParkLayer" has data-bind named "Parks auto-generated Data Bind.". This layer is part of global group "Global Group 1"

- In work-context "Work Context test1" the global group "Global Group 1" has been added. So layer "ParkLayer" is present. Additionally, the work-context has layer "Parks" (from the .mws file listed under Layer Settings") which also has data-bind named "Parks auto-generated Data Bind".

- So when Exponare loads Work Context test1, it comes across the two same-name data binds. When the second instance is encountered, a warning is written to the log "A databind named Parks auto-generated Data Bind. has already been added to this layer Parks ."

Resolution
UPDATED: June 30, 2017Renaming the global layer's data-bind from "Parks auto-generated Data Bind." to something else would resolve the warnings.
For example, the global layer's data-bind named "Parks auto-generated Data Bind." can be renamed to "Parks Global Data Bind"
