问题 Im writing an inbound resource adapter with JCA for a legacy EIS. The EIS does not support XA transactions. The messages however form a conversation that exist of multiple messages.

问题 What order are child components created and mounted in?

For example, what is the creation and mounting order for the following component? <template> <div class='parent'> <child-1/> <child-2/> <child-3/> </div> </template> 回答1: I found this article to be especially helpful in explaining the order of parent/child lifecycle hooks execution. This
