[Table] Scrolling issue [message #657278]

Hi,

while debugging my RAP application with firebug, I encountered a strange behaviour while scrolling in a Table (Viewer) control,

I scrolled up/down several times in the table. I was looking into the firebug network monitor. I saw that while scrolling the mouse cursor position is send to the server. This seems normal for me. But in some cases these requests are send in an infinite loop even when I am not scrolling anymore.

After 5 minutes I have already >500 requests. They all have the same POST information:

w1.cursorLocation.x=-324&w1.cursorLocation.y=369&uiR oot=w1&requestCounter=825

The x-location seems to be negative.

I can reproduce tihs in my application. But I cannot reprodruce it in the control demo.

Is this bug?

Regards,
Oliver

Another observation:

In the control demo:
I scrolled with the mouse wheel in the table. The scrolling was done correctly. But when I hover over the table with mouse, the table seems to scroll by itself (up and down with each hover).

I could not reproduce this a second time.

Forget to meantion. We are using RAP1.4M5

Oliver

Hi Oliver,
looks like an issue with the new scrollbar implementation. Is it
reproducible in other browsers or it is a FF issue only? Could you
provide a snippet to reproduce it? If yes - please file a bugzilla.
Thanks,
Ivan

Hi Ivan,

I could reproduce it with Google Chrome.
I don't know how to check it with IE8, Opera or Safari because there are no addons to trace the network traffic.

I will try to create a snippet.

Oliver

Hi Ivan,

I found out that it is possible to reproduce this behaviour with the control demo. Therefore I think no particularly snippet is needed.

I think it is a timing issue. It only occurs while scrolling fastly (either vertically or horizontally)

Is this information enough to file a bug?

Regards,
Oliver

Hi Oliver,
sure... if it's reproducible with Controls Damo -> Table Tab this is
great. Just specify the steps needed to reproduce it.
Best,
Ivan
