IF you have multiple solutions inside one workspace and switch from one to the other in developer it throws an error about duplicate packages. Is there a workaround for this as its super irritating ? I thought the packages were loaded into the resources space on deployment so am not seeing why there would be a problem with one overwriting the other provided they were the same release.

Hi Gordon,

The packages are attached to a **single solution** (nothing to do with Resources project) so it’s likely that you have a collision somewhere having to do with multiple solutions in a given build path containing one or more of the same packages.

There are two ways a package can be associated to a solutions, and either can produce a collision

1. A zip file in the solutions _ng\_web\_packages_ folder. This is most common and the result of adding a package via the Servoy Package Manager
2. By project reference when running a package from source. This is NOT common

Please scan your build-path for multiple occurrences of the same packages.
