How to manage linked containers with different Widths?

Robin,

I'm working with Air 2.0, and version of the TLF which shipped with Flex 4.1.0.

My code is a bit distributed across various objects in a fairly complex solution but here are the relevant sections.

There are two separate views, each of which creates its own controller:

        protected var containerController:ContainerController;

        protected function renderStoryView():void
        {
            createTextHolder();
            if (!containerController)
            {
                containerController = new ContainerController(textHolder, this.width, this.height);
                containerController.horizontalScrollPolicy = ScrollPolicy.OFF;
                containerController.verticalScrollPolicy = ScrollPolicy.OFF;
            }
            storyFlow.flowComposer.addController(containerController);
            setContainerFormat();
            fixParagraphSpacing();
            updateStoryFlowControllers();
        }

         protected function createTextHolder():void
        {
            tryToRemoveDisplayObject(textHolder);
            textHolder = addChild(new UIComponent()) as UIComponent;
        }

         protected function updateStoryFlowControllers():void
        {
            storyFlow.flowComposer.updateAllControllers();
        }

Normally each view has its own textFlow associated with it, but in the case of two linked views, they share the same text Flow. The code which does that is here:

          if (!ModelTextFrame.IsChild)
            {
                View.StoryFlow = ModelTextFrame.MyParentStory.StoryFlow;
            }
            else
            {
                var parentController:TextFrameController = MySpreadController.GetTextFrameBySelf(ModelTextFrame.PreviousTextFrame);
                View.StoryFlow = parentController.View.StoryFlow; // This View now has the same TextFlow as another one.
            }

This works fine, and the text flows from one container to the next as expected. When a view is resized the following function is called:

     protected function updateControllerDimensions():void
        {
            //AirConsole.Debug("TextFrameView updateControllerDimensions: " + this.width);
            containerController.setCompositionSize(this.width, this.height);
            updateStoryFlowControllers();
        }

This sets the composition size on only the local containerController, but then calles updateAllControllers() on the shared textFlow. The expected result would be for only the local container to change size, but for the text to reflow across both containers to take account of the change. What actually happens is that the dimensions change on both the linked fields.

I've used the debugger to verify that the updateControllerDimensions() function is being called on only one of the views, and to confirm that there are two controllers attached to the flowComposer (one for each view, as expected).

I don't have time this week to break this out into a test application that I could post here but will try to do so next week. In the meantime, anything that might mean I don't have to do that would be welcome.

Many thanks, as always.
