Had the same thing here. Resolved it by replacing the Image (<img>) with a Label (<div>) and gave it a background-image style property. Adding and removing the Label from the dom does not throw the exception in IE.
I am also got this exception, i resolved this. In my case i am removing image from parent while doing this in IE8 GWT runing a thread for changing the proeprites on the image that time it is throwing exception. so instead of removing i just made it hidden, it is resolved

I have googled and found that it may be due to incompatible versions of xercesImpl.jar, downloaded latest jars and tried but no help.
removed xercseImpl.jar and xml-apis.jar, added xerces.jar. But the issue persists.
This problem is fixed in install4j 6.1.6.
I have a page which has a canvas element for E-mail signature.
The application is in gwt. It's working on all other browsers, except IE 10.

Any help appriciated.
According to the stack trace (which is in dev mode), this is about VML, not Canvas. Whatever drawing library you are trying to use is attempting to interact with VML in IE10, which does not support VML.

I am getting here in the below part..
interface DatabaseConstants extends Constants {
String[] contactDatabaseCategories();
}
DatabaseConstants constants = GWT.create(DatabaseConstants.class);
This could be a few things first check you have a DatabaseConstants.properties file to store the values, next ensure that the key contactDatabaseCategories exists and has a comma separated list of values. Also might have to create the constants as a stand alone class
UPDATE
Move the interface to it's own .java file
Create a text file called DatabaseConstants.properties at the same level as the .java file
within that you can put
contactDatabaseCategories=Category1,Category2
That should stop that error and provide you a value for more information take a look at constants

I am using Maven2, GWT 2.3 and JavaSE1.6
I know GWT can serialize ArrayList as I have used it countless times so I cant figure out what in world is going wrong over here.
Could you have forgotten to add the servlet and servlet-mapping entries in web.xml or the #RemoteServiceRelativePath annotation on your service interface?
I'd start by making sure your Async, Service, and Impl classes match up to the RPC specification exactly. GWT will throw an error if you did anything (missing parameter, different return type) differently. Take a look at the google documentation on RPC, they sufficiently describe RPC calls (in a quite lengthy fashion).
The RPC interfaces and implementation do match, otherwise you would not be able to compile. I'm quite sure what you put in the ArrayList is causing the problem. Is it a generic ArrayList or a list of certain types? Try using Java Generic (e.g. ArrayList) to help the GWT compiler optimizing your code.
First thank you very much for your time, I have a problem with the development of an applet to control users via fingerprint, as developed in eclipse using the DigitalPersona SDK, the problem is when I run it from a web page browser,

Thank you very much for any help
good day
You need to add the dptojni.jar to the library of your project, it is in c:/programs files/digital persona/bin/java. Or you can get the class jniException and add it to your project.
Having the same problem, here is someone telling that is necessary put
capturer.setPriority(DPFPCapturePriority.CAPTURE_PRIORITY_LOW);
after calling createCapture to solve it. I will try this answer now.
You have to sign the jar files. That's what I did, and now it's working.
Make sure you have instatiated the DPFPCapture object before calling the setCapturePriority method and also make sure you stop capture after you have finished using the capture object
