Re: How to filter some places in onPlaceChangeRequest in ActivityManager?

It looks like a design problem .

But if you really want to continue in this way , start by reading :

Hi

There is need to filter some places in onPlaceChangeRequest in ActivityManager to prevent call mayStop of currentActivity.

for example, I have ListEditActivity where I can edit list items. This activity managed by ActivityManager this CachingActivityMapper and FilteredActivityMapper.

Also I have ListSelectionItemPlace which indicates currently selected item in the list

After a list item has been edited and selected another item in the list, there is an attempt to change the place to ListSelectionItemPlace

and fired event PlaceChangeRequestEvent. Handler onPlaceChangeRequest in ActivityManager calls mayStop method of ListEditActivity it is returns some message

because item has been edited.

I need to ignore such places change, but I cannot to do it.

method mayStop has no any parameters.

Handle PlaceChangeRequestEvent in ListEditActivity gets no result because event handler is still called in ActivityManager before.

I can subclass ActivityManager for ListEditActivity and override onPlaceChangeRequest method, but I have no access to currentActivity to ask it ignor or not this call.

Have any ideas?
