So, what I tell bellow is with full respect to that. I'm NOT really "complaining" let's say I'm just voicing some concerns from users. This is the second Wicket application I migrate to Wicket 7.0 in last two of months. First application was for a customer and we encountered a few little "surprises", e.g. https://cwiki.apache.org/confluence/display/WICKET/Migration+to+Wicket+7.0#MigrationtoWicket7.0-org.apache.wicket.markup.html.panel.FeedbackPanelDonotsetCSSclassontheli >spanelementforafeedbackmessageWICKET-4831 IMHO changes like this bring no real value and just make migrations less "stable". Not to mention things like this https://ci.apache.org/projects/wicket/guide/7.x/guide/componentQueueing.html which might have made framework slower (according to certain post on list). I know that without changes there is no evolution. I'm just telling that maybe there is a need to make changes more gradually (e.g. deprecate things) and try to introduce features (if possible) in a way that they can be "switched off". Even on OS level there is a requirement note and sometimes API changes have > impact on applications and their complete compatibility. > IMHO users just expect things to work out of the box. More if they are just very satisfied with the version of the product they are using and the only reason they are actually migrating is just to not "fall behind". There was already something called Wicket 2.0 which was abandoned after a few months of development because, if I remember correctly, it broke too much previous version code base. As a user I would like not to experience something similar anymore. I haven't tried yet Wicket 8.x but I'm a bit afraid it might be a bit disruptive for some users/applications. I will want to try it ASAP and give my modest feedback. -- Regards - Ernesto Reinaldo Barreiro
