Hi Nicolas, let me try to clear up some of that fog :) when installing certain features which depend on each other in the same "run" you might end up with a "race-condition" as the required feature isn't installed as it would usually be installed in the same run. One example for this is if you have bundles using the wrap: URL-Handler, those require the wrap-feature to be installed prior to the using feature. To navigate around this, you need to declare your own feature to be dependent on the other feature with a prerequisite.
Now concerning your blueprint bundles, those need to have the blueprint feature installed prior to your own bundle. So in that case you either can set your own bundles start level much higher then the blueprint one and hope that this works out or also set the prerequisite flag on this feature set. regards, Achim 2016-02-19 20:17 GMT+01:00 Nicolas Brasey <[email protected]>: > Hi Achim, > > Thanks a lot for your comment, even if I still don't fully understand what > was wrong, I finally got it to work.
