Error in Enhanced Draw widget

City_of_Port_Angeles_GIS — Thu, 21 Oct 2010 23:00:22 GMT

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,

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.

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,

Copy all of this replacing everything in your DrawWidget.xml

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

Bill,

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

Re: Error in Enhanced Draw widget

City_of_Port_Angeles_GIS — Wed, 27 Oct 2010 14:25:24 GMT

Robert,
I am using the uncompiled version.

Bill,

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

Re: Error in Enhanced Draw widget

City_of_Port_Angeles_GIS — Wed, 27 Oct 2010 22:46:47 GMT

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.

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

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.

Re: Error in Enhanced Draw widget

KwokKin_Wai — Wed, 22 Dec 2010 14:33:24 GMT

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

Re: Error in Enhanced Draw widget

RobertScheitlin__GISP — Wed, 22 Dec 2010 17:05:23 GMT

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.

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

</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?

RobertScheitlin__GISP — Thu, 27 Jan 2011 14:15:53 GMT

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>

Re: Error in Enhanced Draw widget

ShawnKraft — Thu, 27 Jan 2011 14:21:25 GMT

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

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

Re: Error in Enhanced Draw widget

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

.mxml to
private var spatialref:Number = 2264;

Seems to work fine now.

M Giles,

What does your main config.xml look like?
