custom controls - firefox doesn't initiate AbstractWidgetLCA#renderChanges [message #91942]

Dear All,

I'm busy with custom controls.

This is what I'm doing:

1. Implement my MyCustomControl like it was with google maps demo.
2. Then invoke myCustomControl.changeSomething.

As suggested, MyCustomControlLCA#renderChanges will ask myCustomControl
whether it has any changes or not.

3. Internet explorer: renderChanges is invoked automatically.
Firefox: renderChanges has not been invoked until I click to somewhere.

I'm scratching my head.

Hi Dimitry,

renderChanges is invoked for each widget with every request. Could
you provide some more details, ideally a code snippet, on how to
reproduce this?

Cheers,
Rüdiger

So the point is: how to tell the browser that it should issue a request?
Because, sometimes it doesn't do it. Meanwhile, the serverside has
changes to present.

I'm at my own investigation for a bit now. I suspect that it is all
because I have another asynchronous layer, other than ajax.

Dmitry,

I am not quite sure what you are trying to achive. To clerify, could
you send some code or share some more details?

Did you read the custom widgets tutorial? There you should find how
to send request to the server.

The UICallBack class provides means to tell the client that there
are changes on the server-side that should promoted to the client.

Hello Rüdiger,

I've read the tutorial. And it seems that UICallback is just what I need.

Thanks.
