I assume you're talking AIR rather than true Flex, right? Synchronous database queries were added in beta 2.

I'm having a productive day ;) ) I'm trying to lift the creation of components to a new level (at least, for me) What I have: (if it is possible...) 1. I have an .AS-class which describes a person. To keep it simple, the person only has a name(String) and a photo(String - the URI). 2. A/ I have a databasetable with the following structure ObjectClass | propertyName | renderType B/ Another database table as follows renderType | bindPropertyName 3. I have an AS-class(UICF) in my own lib, having following method public static getUIComponent(object:Object, objectClass:Class, propertyName:String, propertyType:Class):UIComponent 4. I have a canvas What should happen: In the creationComplete of the canvas(4) a new Person is created: var p:Person = new Person("Foo", "images/bar.jpg"); Now the canvas(4) calls the getUIComponent(3) for rendering the image: var c:UIComponent = UICF.getUIComponent(p, Person, "photo", String); The method(3) returns the correct component, being an imagecomponent and the canvas(4) just adds it to it's children: this.addChild(c); The problem is inside getUIComponent(3). This method should do a call to my database to find out which type of component it should create and which property to set. For this example, the db would look like this: First Table ObjectClass | propertyName | renderType Person photo Image Second Table renderType | bindPropertyName Image source However, if I recall correctly, all database requests made by Flex are Asynchronous. One option I see, is to have a boolean which gets sets by a resulthandler, and create a lock-up-loop in getUIComponent. However there might just be another (better?) way, to wait for my response and then create and return the correct component. Thanks in advance, --Johan
