Vaadin not working at all in Blackberry Playbook browser

[Alberto]

Web pages developed with Vaadin are not working at all in Blackberry Playbook (and by now are the only ones I have seen are not working. www.gwt-ext.com/demo is working properly for example)

When go to any web page developed with vaadin get the following error:

Widgetset does not contain implementation for null.Check its @ClientWidget mapping, widgetsets GWT module description file and recompile your widgetset. In case you have downloaded a Vaadin add-on package, you might want to refer to add-on instructions. Unrendered UIDL:

Then you get a tree with this kind of information: 1 id=PID1 height=100.0% width=100.0% margins=0 alignments={} expandRatios={PID16:1,}

You could try adding "?debug" to the url and see if you can get any hints from the debug console.

Just tested the BlackBerry Playbook Simulator using  http://demo.vaadin.com/Calc and  http://demo.vaadin.com/sampler without any problems.

just tested again and Vaadin isn't working. This is a real SHOWSTOPPER.

I uploaded 3 screenshots from today at  http://ge.tt/8PEPcx6?c

Can this be reproduced without an actual Playbook (which I don't have)? As mentioned I have tested using the Playbook Simulator and there everything works fine.

hmmm just installed Simulator 1.0.6 and your samples are working and also our application. (of course we have still some work adding touch events....)

but using this from real devices it doesn't work as described above tried from different locations with different PlayBooks

I also asked at BlackBerry Support Forums

Hey folks, Adam here from BlackBerry Developer Relations. I can confirm that on Tablet OS v1.0.7 (current in-market OS release), the following error is being displayed for the "Calc" app listed above :

"Widgetset does not contain implementation for null. Check its @ClientWidget mapping, widgetsets GWT module description file and re-compile your widgetset. In case you have downloaded a vaadin add-on package, you might want to refer to add-on instructions. Unrendered UIDL:"

This suggests the Vaadin framework is not able to render the page for this version of the Tablet OS and an error is occurring before any page rendering even occurs. Vaadin - can you confirm the cause of the above error?

I suspect a behavior that Vaadin depends on might have changed between 1.0.6 and 1.0.7. Lets try and identify what the dependency is (need to have the Vaadin folks look into the root cause of the error message above) and then we can confirm whether any behaviors have in fact changed (or whether a bug was introduced in 1.0.7 that can be resolved).

If there is in fact a Tablet OS bug, please file any issues here:  https://www.blackberry.com/jira/secure/Dashboard.jspa

Best, Adam Stanley

hi adam, thanks jumping into this.... the problem is the folks at Vaadin don't have a PlayBook device - and using latest Simulator 1.0.6 it works well. so the problem is how they should know what goes wrong ?

for me the dilemma is, that our software (Open Source project redVoodo.org) depends on Vaadin and Vaadin runs well in browser, 1.0.6 Simulator, iPad and iPad2 but I have to make an offer for a business software project for a company from canada ;-) where Vaadin / redVoodo is used for web-application running on PlayBook together with BlackBerry OS 6 SmartPhones Java Applications and I cannot demonstrate the Vaadin-based software on PlayBook :(

perhaps there is a way for RIM to provide a PlayBook for Vaadin team

The message "Widgetset does not contain implementation for null." indicates that there is a problem with parsing the JSON data returned by the initial XHR request. Scrolling down in the debug window might give some clue, should contain something like

Making UIDL Request with params: init
Server visit took 121ms
JSON parsing took 0ms
[-] change format=uidl pid=PID0
	[+] com.vaadin.terminal.gwt.client.ui.VWindow id=PID0 height=891px width=1680px caption=Calculator Application name=1 theme= resizable=true main=true
	[+] variables
	[+] com.vaadin.terminal.gwt.client.ui.VGridLayout

Still I have no good guess on what could go wrong without a way to reproduce it. Is there a new version of the simulator coming up where this could be reproduced?

Of course if somebody wants to send us a Playbook device we will be happy to test on that.

hi artur, wasn't easy to expand and copy from the debug window on PlayBook, but here's the beginning. perhaps it helps you

just tested with 1.0.7.2942 from today: same problems as before

[Artur Signell]

A small HTML test that could show the problem:  http://artur.virtuallypreinstalled.com/vaadinjson.html (imitates the JSON parsing that takes place in Vaadin in the HelloWorld example)

Please compare the output from a browser (e.g. Chrome) and a Playbook. I suspect the typeMapping (last part) is the problem.

[ekke@…]

Artur, thanx for testing these isuues. I tried your site on Chrome (OSX), PlayBook Simulator 1.0.6 and real PlayBook device 1.0.7 for me it looks ok uploaded screenshots here:  http://ge.tt/8PEPcx6 ekke

Vaadin Calc

As you can see, the problem persists. I checked 6 months ago, checked today, and still the same (PlayBook OS 1.08 now, real device).

Vaadin Sampler on PlayBook OS 1.08

[Artur Signell]

Tried with the latest Playbook Simulator (1.0.8) - everything still works fine using that... One way to debug it seems to be using the "web inspector" which allows you to open another tab and see the Javascript console etc. Maybe there is an error message that could give a hint what is going on?

[mortcj@…]

We are experiencing a similar problem with a blackberry phone. It appears that a blackberry running OS 6 can open the Vaadin sampler and OS 7 cannot. Is there a mapping of the user agent string that needs to be updated?

More likely something that has change in Blackberry OS 7. There are no special cases for Blackberry in Vaadin

Good news!!

It's working on Playbook version 2.0 !!

Regarding BB OS7 I'm afraid is not, I'm afraid a similar error is obtained when trying to see the webpage.

[Adun]

I can confirm that Vaadin 6.7.6 works fine now on PlayBook 2.0. (same old device with upgraded firmware). Also dontpush-ozone works fine.
