Hi
I'm using the gwtgl library. There's one method invocation in it which
throws an exception in hosted mode but seems to work OK in compiled
mode. I suspect that the answer is obvious... Any suggestions would be
greatly appreciated...
The actual lines of code are:
float [] perspectiveMatrix = createPerspectiveMatrix(45, 1,
0.1f, 1000);
WebGLUniformLocation uniformLocation =
glContext.getUniformLocation(shaderProgram, "perspectiveMatrix");
checkError();
glContext.uniformMatrix4fv(uniformLocation, false,
perspectiveMatrix);
and as I said, it works fine compiled and fails in hosted mode. If I
stop the debugger at glContext.uniformMatrix4fv(.... it gets there OK,
but as soon as I step into it the debugger it fails at:
protected JsValue doInvoke(String name, Object jthis, Class<?>[] types,
Object[] args) throws Throwable {
TreeLogger branch = host.getLogger().branch(TreeLogger.SPAM,
"Invoke native method " + name, null);
CompilingClassLoader isolatedClassLoader = getIsolatedClassLoader();
JsValueOOPHM jsthis = new JsValueOOPHM();
Class<?> jthisType = (jthis == null) ? Object.class : jthis.getClass();
JsValueGlue.set(jsthis, isolatedClassLoader, jthisType, jthis);
branch.log(TreeLogger.SPAM, " this=" + jsthis);
int argc = args.length;
JsValueOOPHM argv[] = new JsValueOOPHM[argc];
for (int i = 0; i < argc; ++i) {
argv[i] = new JsValueOOPHM();
JsValueGlue.set(argv[i], isolatedClassLoader, types[i], args[i]);
branch.log(TreeLogger.SPAM, " arg[" + i + "]=" + argv[i]);
}
JsValueOOPHM returnVal = new JsValueOOPHM();
try {
channel.invokeJavascript(isolatedClassLoader, jsthis, name, argv,
returnVal); <--- EXCEPTION THROWN HERE
branch.log(TreeLogger.SPAM, " returned " + returnVal);
} catch (Throwable t) {
branch.log(TreeLogger.SPAM, "exception thrown", t); <---
Exception is "invoke of
@com.googlecode.gwtgl.binding.impl.WebGLMethodsBinding::uniformMatrix4fv(Lcom/googlecode/gwtgl/binding/WebGLUniformLocation;Z[F)"
failed
throw t;
}
Thanks
