Re: [p2-dev] combined UninstallAndInstallOperation

Hi Andrew,

What you are trying to do is not possible with the Operation API (operations can't be composed).
However achieving what you want is entirely possible using the planner API (e.g. ProfileChangeRequest). For example on how to use this API you can take a look at the computeProfileChangeRequest method in InstallOperation / UninstallOperation or in DirectorApplication#buildProvisioningRequest (in the bundle).
