Error in Enhanced Draw widget

City_of_Port_Angeles_GIS

Robert,
I followed your instructions for integrating your enhanced draw widget into my Flex Viewer app
but I'm getting the following error:
Fault info: Error #1090: XML parser failure: element is malformed.
I have not changed anything in your code. All search results on google refer to Action Script 3.
The problems window in Flash Builder 4 does not display any errors at all. Any ideas what could be causing this?
Bill

OK here is my config.xml. Alot of my layers could not be shown on public forums so I removed them - everything that i removed i commented out and the errors still exist so they are not the problem. Thanks!

Nope... I want to see if you have a syntax error in the WHOLE config.xml

M Giles,

What does your main config.xml look like?

Hi Robert.

I am having problems with the enhanced draw widget:

I get the following 2 errors when drawing with the widget. The first error occurs when drawing points, lines, extents, and polygons. The second error occurs when drawing freehand lines, freehand polygons, circles, and ellipses.

[FaultEvent fault=[RPC Fault faultString="Unexpected < encountered" faultCode="null" faultDetail="null"] messageId=null type="fault" bubbles=false cancelable=true eventPhase=2]

[FaultEvent fault=[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"].

I am using compiled version. Just downloaded the latest version and it didnt help. My map is in lambert conformal conic (wkid 102002) if that could have anything to do with it.

My xml is as follows:

I have tried replacing it with the xml you provide in this thread but that did not help.

PaulTHEDUDELang

Changed from:
.xml
<spatialref>26913</spatialref> to <spatialref>2264</spatialref>

.mxml to
private var spatialref:Number = 2264;

Seems to work fine now.

PaulTHEDUDELang

Version 2.2.4 - 02/24/2011
Info on previous versions is in the ReadMe.txt

Getting error on double click to end measure tool. Occurs after sitting idle for a few minutes.

[FaultEvent fault=[RPC Fault faultString="Unexpected < encountered" faultCode="null" faultDetail="null"] messageId=null type="fault" bubbles=false cancelable=true eventPhase=2]

ShawnKraft1

That worked. Thanks Robert. For some reason I thought I had to use wkid for my area.

rscheitlin

Shawn,

The draw and my enhanced draw widget have always required the WKID to be one that uses meters.
Try and use the WKID: 26913 instead:

<spatialref>26913</spatialref>

ShawnKraft1

Hey Robert, the widget works well but my measurements are off. Here is what I have

<geometryservice>http://icarus/ArcGIS/rest/services/Geometry/GeometryServer</geometryservice>

</pointunits>

Measurements are off only with area and perimeter and I can't figure out why. I have it pointing to my own geometry service set to our area for WY state plane. Any ideas?

rscheitlin

John,

So like I said when you check it from a machine that does not have flash builder debug version you will not see those options.

KwokKin_Wai

Dear Robert,
Exactly, after I complied the programe and put the program to ArcGIS server, the functions gone when I open the web for displaying. I don't need to worry about these functions in web environment.
Thank you for your help

John

rscheitlin

John,

You must be talking about "show redraw regions" that is something that you only just when you use a machine that has flash player debug version. You don't get those options on a normal version of flash player so no need to worry about them.

KwokKin_Wai

Dear Robert,
The enhanced Draw Widget work fine, however, when I use the mouse and click on the polygon that I drawn, right click the mouse, apart from the "Clear Feature" options, there are two other options below. when I select these two options, the function displayed a lot of red outline rectanlge and gone mad....how can I disable these two options if I don't need them?

Thank you for your help and look forward to your reply

John

City_of_Port_Angeles_GIS

Robert,
That was the answer! Works like a charm and NO ERROR MESSAGES! Beautiful widget Robert,
keep up the good work and thanks again for all your help.
Bill

rscheitlin

Bill,

I don't really have a clue why you are running into this issue. Can you download it again and replace everything?

City_of_Port_Angeles_GIS

Robert,
I am using the uncompiled version.
Bill

rscheitlin

Bill,

This is very strange. Are you using the compiled or uncompiled?

City_of_Port_Angeles_GIS

Robert,
   Thanks a lot for taking the time to answer. I'm sure the demands on your time are pressing if they're anything like what I have to deal with here.
   I pasted in your code but I still get the same error message when I try to draw anything that has an area. The drop down menu for area units is still empty. I tried the Adobe help for Flash 4, but couldn't
seem to find anything that pertained to my problem. If I could just figure out why the drop down menu isn't being populated, I think I might be able to resolve this. So far no luck. Any more ideas
would be greatly appreciated.
   Also, does ESRI have an MVP for this forum and if so how do I vote?
Bill

rscheitlin

Bill,

Copy all of this replacing everything in your DrawWidget.xml

Robert,
That was the problem! Thank you very much. The widget works fine now except when I try
to draw a polygon, circle or ellipse. I then get an error message from flash. I noticed that the units
drop down for distance is populated (meters, feet, etc.) but the one for area is empty. This is the
error message I get:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

I've checked the DrawWidget.xml and I don't see anything wrong. No missing carets, no misspelling, etc. The polygon gets drawn, but the area does not display.
Bill

rscheitlin

Bill,

Something must have happened to the xml text you are putting into your config.xml or somehow the DrawWidget.xml has gotten corrupted. Check for syntax errors in both.
