Map is not displayed when spatial Reference is explicitly specified.

Shimonchh — Tue, 06 Apr 2010 06:05:41 GMT

I am using Flex Sample Viewer 1.3.

When I write following my map is displayed but Draw Widget doesn't work . Project Complete Handler event is not called.

var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]));

but when I write

var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]),new SpatialReference(4326));

DrawWidget works but map is not displayed.
Please suggest me something to solve this problem.

Shimon31,

I have to admit you have me a little confused here. In the SFV 1.3 this line of code is there by default

var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]));

and both the map displays and the draw widget works...

When you say that you set the code to

var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]),new SpatialReference(4326));

and the map does not display but the draw widget work, what is the spatial reference of you map services that are in the map? are you using the default OLD basemaps or the newer ones that are in WKID 102100?

Draw widget doesn't work

thanks for your reply sir

yae this is the default line

var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]));

but when i draw a line by using draw widget projectCompleteHandler function is not called. and no result is shown

but when i changed this above line of map manager like this

When you say that you set the code to

var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]),new SpatialReference(4326));

then draw widget works. it gives lenth of line but map is not displayed . although i can retrieve all values of map like name of layers etc.

spatial reference of my map services is 4326.

Shimon31,

    The fact is that the SFV 1.3 works out of the box using basemaps in 4326 (both map display and the draw widget). With the minor exception of dynamic maps that is discussed here in this thread http://forums.esri.com/Thread.asp?c=158&f=2421&t=297291&mc=3#927860.

    If the dynamic maps issue is not your issue than either you have changed some code or your map services are in another projection. It really doesn't matter if your map services are in another projection as long as they are added as they are added to the livemaps or basemaps section of the config.xml with a type value of dynamic.

   What is your map services WKID? Maybe you should post your config.xml.

pls give any suggestion...

Shimon31,

    The fact is that the SFV 1.3 works out of the box using basemaps in 4326 (both map display and the draw widget). With the minor exception of dynamic maps that is discussed here in this thread http://forums.esri.com/Thread.asp?c=158&f=2421&t=297291&mc=3#927860.

    If the dynamic maps issue is not your issue than either you have changed some code or your map services are in another projection.

shimon31,

WGS 1984 Lambert Conformal Conic is not the same as WGS 1984.

Here is a quote from the Spatial Reference Class of the AGS Flex API.

Each projected and geographic coordinate system is defined by both a well-known ID (WKID) or a definition string (WKT). The ArcGIS API for Flex (and the underlying ArcGIS Server REST API) only supports well-known IDs (not definition strings).

Your map service does not have a Well Known ID (WKID), hence the issues you are having. Only suggestion I have for you is to re-project your data into a WKID.

Thank You

Thank u sir for ur suggetions
i have changed projection of the map and now all functions are working
