Re: ClassCastException in generics

Kirill,

I am out of suggestions for but my curiosity drives me crazy.

What are you trying to do in java terms? For example:

• Are you try to return an ArrayBuffer from a function: public <T> T getBuffer();
• Are you try to pass an ArrayBuffer as a parameter: public <T> void sendBuffer(T buffer);
• Are you try to put the ArrayBuffer in a List, Array, Set?
• Something else?

I looked but I didn't find in the thread the description of the java caller that throws the exception.

Sorry, copypaster error, here is the fixed

getType(buffer) = [object ArrayBuffer]

typeOf(buffer) = object

Here it is:

getType(buffer) = [object ArrayBuffer]

typeOf(buffer) = [object ArrayBuffer]

private native String getType(Object x) /*-{
    return Object.prototype.toString.call(x);
}-*/;

private native String typeOf(Object x) /*-{
    return typeof x;
}-*/;

Take the object you get back from the file reader and run it through the JSNI method below and GWT,log the result. .Let's see if it really is an ArrayBuffer.(I would note the FileReader result is sometimes a String and sometimes an ArrayBuffer).

private native String getType(Object x)/*-{      return Object.prototype.toString.call(x);  }-*/
