Hello everyone,
I faced with on problem and want to make sure is it a defect or troubles in my code. Might be some one of you faced with that.
I have a TextItem field:
for this field I added KeyUpHandler:
Then run project and try to push ';' or ':' (shift+';' ) buttons. After that I'm getting Null pointer:
Somebode knows what is that? or it is a defect?

I have a TextItem field:
Code:
final TextItem regUsername = new TextItem("regName", "Username");
regUsername.setRequired(true);
Code:
class MyHandler implements ClickHandler, KeyUpHandler {
public void onClick(ClickEvent event) {
sendRequestToServer();
}
public void onKeyUp(KeyUpEvent event) {
if (event.getKeyName().equals("Enter"))
sendRequestToServer();
Code:
