I am not aware of anyone else having run into this. Can you please make an attempt to put together a test case that reproduces the hang?
Hi Corey,The screen where my application 'froze' contained a few mx:FormItem elements inside Group containers (and not inside a Form container). I replaced FormItems with HBox and VBox and that particular issue got resolved!! You may want to look into this issue in light of this discovery.However, even after implementing this 'fix', I'm facing yet another issue in the same component and I'm not sure if the underlying root cause is the same. I have created a sample application to bring out the issue.I've put up this sample application at: http://22.214.171.124:9080/OCNIssue/OCNIssue.html (view source enabled)Application description: The application reads a simple XML data file (in the real app, it's a Spring-BlazeDS service) and renders the information. It allows user to add more data / update existing data. I'm using two-way binding for adding / updating data.Issue description: Two-way data binding wipes clean first selected record in the model. Works fine then onwards. It's as though, blank fields in the view overwrites model before model has an opportunity to populate the view.Please follow this workflow to reproduce the issue:1. Hit the URL2. Click on the place holder image for any of the 3 data elements3. Click on Update button4. You'll notice that the form is blank. The data, where two-way binding was used, corresponding to the selected raw has gone blank. The component is (VideoAddUpdateCore.mxmlIf you replace the two-way binding with Flex 3 type one-way binding in this component, it'll start behaving as expected! Replacing @ with a reverse binding using fx:Binding leads to the same issue described above.Let me know if you need any further clarification on this.Dilip
If you create a JIRA bug for the Group/FormItem hang, someone can address.
I would suggest promoting your two-way binding issue to a new thread, as I'm sure there are folks with domain expertise that can help you.
