obx kicks in ONLY after hot-reload!

[natgross]

In my controller I have a list defined: final xEntitiesResultListMainDb = <TestEntity>[].obs;
In a (db query) function I do: xEntitiesResultListMainDb.assignAll(newQueryResultList);
In my stateful widget/view I inject the controller: final xController = Get.find<FirstGetxController>();
Then a view wraps a List builder with obx, displaying a ListTile per item.
The problem:
Nothing happens when updating the obs list in the controller, even when using assignAll().
BUT! (This is the funny part.) If I hot reload (device connected to windows machine on vscode), voila! The (obx) list appears promptly (as expected in the first place) without any further input.

The same phenomenon occurs with other variables contained in the entities in the list. They appear as expected ONLY after a hot reload.

Thanks,

AND the answer is...
You shouldn't build an obx wrapped widget as an argument to an else statement.
Here is a snippet of incompatible code:

           Container(                
                child: isSomeConditionTrue?
                    Text("-------------")
                    : Obx(
                        () => ListView.builder(...

When I removed the if-else, and had the Obx directly as the child, all is ok!

But what if I need 'if' :), And I find out that even if you have 'if' in a function which is updating the [list] behaviour the same :(
