It doesn't reload the collection in datatable[upgrade from rf3.3.3 to rf4.1]

Hi guys,

I met an issue about the collection refresh.

When I delete one row and then go to the same page, the model collection doesn't refresh.

Firstly, I like to show my code:

This is the datatable code:

<rich:dataTable id="itemList" width="100%" rows="#{groupsBean.pageSize}" value="#{groupsBean.groupList}" var="group" rowClasses="tb_row_1,tb_row_2">

  ...

</rich:dataTable>

This is the java code, this class is a viewscoped one:

@ManagedBean

@ViewScoped

public class GroupsBean extends DirectoryBean {

  private ArrayList<Group> groupList;

...

  protected void freshList() {

...

       groupList = groupHandler.getAllGroup(memberId, getPageIndex(), pageSize);

...

  }

I have to change the code as the below, it will work well:

          protected void freshList() {

...

               ArrayList<Group> list = groupHandler.getAllGroup(memberId, getPageIndex(), pageSize);

               groupList.clear();

               groupList.addAll(list);

...

          }

I suppose, it's jsf2 mechanism of the page state.

Do you have some idea to solve this issue?

Thanks,

Eric Han

I found getGroupList(groupsBean.groupList) is invoked earlier than freshList invoked.

I expect flow is:

delete->freshList->getGroupList

It's so wiered, why page getting invoked firstly? It doesn't keep to the six lifecycle.

This is the request processing lifecycle log:

show list page:

--->Before RENDER_RESPONSE 6

fresh list.

get group list.

<---After RENDER_RESPONSE 6

do delete:

--->Before RESTORE_VIEW 1

<---After RESTORE_VIEW 1

--->Before APPLY_REQUEST_VALUES 2

get group list.

<---After APPLY_REQUEST_VALUES 2

--->Before PROCESS_VALIDATIONS 3

<---After PROCESS_VALIDATIONS 3

--->Before UPDATE_MODEL_VALUES 4

<---After UPDATE_MODEL_VALUES 4

--->Before INVOKE_APPLICATION 5

fresh list.

<---After INVOKE_APPLICATION 5

--->Before RENDER_RESPONSE 6

get group list.

<---After RENDER_RESPONSE 6
