PictureMarkerSymbol with SWF not visible until Map zoomed

Ranga_RaoGadiparthi — Fri, 05 Nov 2010 17:16:39 GMT

I am trying to add a red glow symbol on a the Map using picturemarkersymbol.
I can't see the glow symbol, until I zoom/move the map.
I am using flex esri lib 2.1.

Here is the sample code.

Thanks for reporting this.
Removing width and height from the pictureMarkerSymbol makes it work (ofcourse without the required size of the swf.)

Ranga,

This is a bug right now in the 2.x Flex API version. The bug is for embedded swfs, when setting width/height.

As a workaround for now, you can either use the swf with the default size or try creating one beforehand with the size you want.

Hope that helps.

Is this width/height of SWF issue still a bug as of version 2.2 of the API?

Yes this is still an issue.

Yes this is still an issue.

Is this width/height of SWF issue still a bug as of version 3.2 of the Flex API?

I tested with the Flex API 2.3 and can verify that the issue with the SWF not loading is no longer there. Here's the MXML that I used:

hi, I met a different bug with swf and png.when zooming the map,the locations of swf and png are not in the same place(with the same point).
here is the url http://forums.arcgis.com/threads/50864-Flex-API-2.5-PictureMarkerSymbol-load-swf-bug?p=173886&posted=1#post173886
