How do I do this? How to get the selected rows or their data in a backing bean? Or would it be better to do it with <h:selectManyCheckbox> ? 回答1: Your best bet is to bind the h:selectBooleanCheckbox value with a Map<RowId, Boolean> property where RowId represents the type of the row identifier.

Here is the summary of what i've done. Model classes: @ManagedBean @RequestScoped public class

问题 Before asking this question, I visited many other related ones and tried to gather the maximum of information. But, what I found till now let me understand that there is no real/major difference between ui:repeat and h:dataTable , and that whenever we can use h:dataTable we can also use ui:repeat (sometimes one of them is a little complex than the other, but at the end we got same results). So, is there any use cases where the only choice is to use h:dataTable ? or the opposite (only choice
