GWT serialization problem

[Вадим Коваленко]

Hello, in my app I faced a problem when reloading some pages. The error is: 

com.google.gwt.user.client.rpc.SerializationException: 
java.lang.RuntimeException: Unable to find class 
com.google.gwt.user.client.rpc.core.java.lang.Long_FieldSerializer

 I've downloaded gwt sources and found that error is caused by this line:

Class? klass = ReflectionHelper.loadClass(typeHandlerClass);

in file com/google/gwt/user/client/rpc/impl/SerializerBase.java

When we navigate to the page with hyper links or enter url manually 
everything works perfect, the code above is working, the class is loaded. 
But when we hit F5 button on some pages, the exception appears.

Refresh button hangs up GWT application

[Вадим Коваленко]

 
   
I have a problem with my GWT (2.5.0) app: on some (not all) pages when user 
hits refresh or F5 button, my app stops responding and only shows loading 
wheel. For example, on page 

http://127.0.0.1:/portal/index.html?gwt.codesvr=127.0.0.1:9997#categories 

refresh works fine, but on 

http://127.0.0.1:/portal/index.html?gwt.codesvr=127.0.0.1:9997#dataset/1474

it doesn't, and I should manually go to 
127.0.0.1:/portal/index.html?gwt.codesvr=127.0.0.1:9997 to make it up 
again. When my app starts first time i have this message:

When I hit refresh, I got this:
