UICallbackManager#releaseBlockedRequest in 1.5 requires manual trigger [message #802035]

Hi all,

Our RAP unit tests depend so much on UICallbackManager#sendImmediately()
to send notification to client.

Since 1.5 it seems to be replaced by releaseBlockedRequest() but somehow
we have to trigger it manually to make it work (by clicking somewhere in
the browser, etc), otherwise our tests will be frozen. This of course
breaks our automate tests.

Any help would be greatly appreciated.

Thanks & Regards,

Setya

Hi,

The problem is not in releaseBlockedRequest method but a call to
Display#sleep() afterwards which waits for events which I have to
trigger manually. I'm not sure why this works fine in < 1.5.

Please advice.

Regards,

Setya

Hi Setya,

the UICallBack system has been completely restructured in 1.5. There is
a wiki page that explains how it works. If this does not help, you'll
have to provide some more detail about your needs.

Regards, Ralf

...
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
page.showView("someViewId");
UICallBackManager.getInstance().sendImmediately();
Display.getCurrent().sleep();
...

The above code works fine in 1.4 in that the view is visually displayed and we can move to the next execution.

Since 1.5 we have to replace the call UICallBackManager#sendImmediately by UICallBackManager#releaseBlockedRequest(). I've checked the source code and they do exactly the same.

...
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
page.showView("someViewId");
UICallBackManager.getInstance().releaseBlockedRequest();
Display.getCurrent().sleep();
...

In 1.5 the above snippet opens the view but the execution always stops at Display#sleep until I manually trigger it by clicking somewhere in the page.

Hope I make it clear this time.

Thanks & Regards,

Setya

Hi Ralf,

Thank you for your response & link.

In our unit tests after we trigger some actions that update the UI we always call UICallManager#sendImmediately and Display#sleep to make sure the update visually reflected.

For example:

...
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
page.showView("someViewId");
UICallBackManager.getInstance().sendImmediately();
Display.getCurrent().sleep();
...

The above code works fine in 1.4 in that the view is visually displayed and we can move to the next execution.

Since 1.5 we have to replace the call UICallBackManager#sendImmediately by UICallBackManager#releaseBlockedRequest(). I've checked the source code and they do exactly the same.

...
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
page.showView("someViewId");
UICallBackManager.getInstance().releaseBlockedRequest();
Display.getCurrent().sleep();
...

In 1.5 the above snippet opens the view but the execution always stops at Display#sleep until I manually trigger it by clicking somewhere in the page.

Hope I make it clear this time.

Thanks & Regards,

Setya

Hi Setya,

I still don't understand your test setup and why you need to access
internal methods. From which thread do you trigger the UI changes?
Whatever you're doing, it would be preferable to try doing it using API
calls. Have you tried Display#wake() instead?

Regards, Ralf

Since those methods are all I know that I can use to tell the client to
update UI.

> From which thread do you trigger the UI changes?

From main test thread.

I tried Display#wake and while it made the test pass, the UI updates are
not visible.

Would you please give example to achieve the same as you suggested ?

Thanks & Regards,

Setya

Hi Setya,

to be able to help you I'd really have to understand your test setup.

Hi Ralf,

You can take a look at the code in
org.eclipse.rap.junit.RAPTestCase#notifyClient. This class was created
by RAP Team to unit test RAP apps.

Thanks & Regards,

Ok, you're using RAP Junit - this was the missing piece. Could you
please open a bug for the problem?

Thanks, Ralf
