Konrad,

This looks like a case where you are using a metadata-less repository ... if so you, should add the following method to your baseline class:

projectClass
  Smalltalk at: #'MetacelloCypressBaselineProject' ifPresent: [ :cl | ^ cl ].
  ^ super projectClass

This mod will cause packages to be unconditionally loaded ... Monticello does a definition comparison on package load so only changed definitions are loaded into the image ...

Hope this helps,

Dale

H Cyril,

Fetching, loading and post loads should leave a trace during the
execution in the Transcript.

Thanks, that helps to confirm that my postload is never executed when I
update a package + baseline in an image that already had an earlier
version loaded. Nothing at all is shown in the Transcript. Reloading the
package and/or the baseline package doesn't leave any trace either. And
if I add a dependency, then update the package again, the new dependency
is not loaded either.

Hypothesis: baseline changes have no effect for already installed packages.

When I load my modified package + baseline into a fresh image, lots of
actions are shown in the Transcript, including the execution of my
postload action. But in that situation, I don't actually need it.

Cheers,
  Konrad.
