map click event listener on latest flex api

AndrewThomas

I have a flex application I am migrating from API 2.4/Flex SDK4.5 to API 3.1 (December 2012 release)/Flex SDK4.6.

The application has an editing of feature layers without using the editor.

I have a feature layer with a click event listener.
This feature layer click event handler shows an info window and adds a map click event listener to the map.
The map click event clears the layer selection and hides the info window.

In other words, user clicks on a feature and a pop up appears. If the user clicks anywhere on the map, the feature is deselected and the popup hides.

After the migration however, the map click event handler is called even though the listener is added by the feature click event handler. It seems like it's remembering the map click event (when the user clicked on the feature) and when the map click event listener is added to the map, the map click handler is called from an event that occurred before it started listening (an echo perhaps?).

Don't believe me?

Try this (it only takes a few minutes):

In Flash builder:

• Create a new project using the 4.6 SDK
• Add an SWC reference to the 12/12/12 ArcGIS for flex API library in the project properties (Flex Build path)
• In the default mxml file, copy and paste the contents from the edit without editor sample below
• Run the mxml (in debug mode preferably)

In the Browser:
If no polygon exists:

• Create a polygon
• Click the 'select features by rectangle'
• Click on the rectangle to change the tool.
• Click 'Clear Selection'

When a polygon exists:

• Click in the feature and try and change the vertex points.

They disappear a split second after the feature is clicked which is different behaviour to the on-line example.

• Add a break point on the map click event handler to show that this is in fact being called when the feature is clicked.

However, presumably the samples are using the latest 12/12/12 API release (from what I can tell from the swf file modification date), which means there is something with my environment which is causing this problem???? I would appreciate someone else trying to replicate this problem.

I did notice the layer click handler method had a remove listener function right before it's added again. I don't know if that was a vain attempt to try and 'forget' existing map click events?

Older versions of the API used to have an automovetotop function that could be used to automatically move the graphic to the top of the stack on mouse over, but this seems to have been depreciated in 3.1:

could this have caused your problems?
