The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

How to attach event listeners to custom components created in run time.

Asked by wildcard76 in Adobe Flex

Tags: , , ,

Hello All,

I have a custom component called layoutPhotoItem and it  has a event called meSelected, which is dispatched when someone clicks on the component.
A function in the main application called listenMeSelected is supposed to handle the logic when the component is clicked.
If I drag a layoutPhotoItem from the user interface of flex builder and handle the event there everything works fine.

But when I try to do it by code, like in the sample I pasted below, I get a
1119: Access of possibly undefined property meSelected through a reference with static type layoutPhotoItem.
error and the IDE wont comply.

I'm quite new to flex but not to coding, I'm guessing I'm missing something fundamental.
Can anybody help me on this ?

Thanks in advance

Cheers

this works fine... the event is dispatched, listened by te handler etc.
<ns1:layoutPhotoItem x="440" y="200" meSelected="listenMeSelected(event)">
 
this one fails..
 
private function addPhotoitem():void{
	var pi:layoutPhotoItem = new layoutPhotoItem
	addEventListener(pi.meSelected,listenMeSelected) // this line fails...
	this.addChild(pi)
}
