return points from labelPointsCompleteHandler

WilliamBailey — Tue, 10 Aug 2010 11:53:01 GMT

I need to return points from geometryService.labelPoints via the labelPointsCompleteHandler function. I have some irregular shaped polygons and I need the labels/infowindow flags to be inside the polygon. Anyone have an idea on how to use this function to return the actual mapPoint to a calling function. The sample only uses "user" drawn graphics, I will be passing parcel polygon graphics one at a time.
I have used model builder in past to accomplish this by using "inside" option of poly-to-point tool, but it requires double querying (polygon and point layers). I was hoping to accomplish this in a more efficient manner.

p.s. I am still using Flex 1.3

William,

In 1.3 API you will have to do a query first so that you can have the graphic of the polygon returned to you and then you can feed that graphic to the geometryService

GeometryService.labelPoints([graphic]);

I have that part covered, I really think my problem is timing issue because I call simplify during an async onResult function for graphical query... the arrayCollection I'm trying to access after this call doesn't exist yet.

Problem solved: Instead of trying to get mappoint right away, I call another function to return it, this seems to give enough time for label_complete to happen.

thanks for your help
