Just try to recompile the database with gwt 2.2

It does appear to be a simple recompilation.

See this bug in another project for more details:

I tried recompiling against GWT 2.3.0 (on Windows Vista) but I got the 
following error:

Does this look like something silly on my part or is there a problem with GWT 
2.3?

Thanks,
Phil

Hi Phil,

It looks like you are compiling the 'appcache' module which is in a, let's say, 
'experimental' state :-) That code won't compile to any GWT 2.x release.

However, if you CD into the /database module of your gwt-mobile-webkit 
checkout, enter "ant clean dist" command, it would compile with any GWT release 
(GWT 2.3 gives errors related to missing validation types, but won't affect the 
result. Working on that).

HTH,
Bart

Hello

Done the following:

- Tried HelloDatabase in dev mode on Chrome (12.0.742.122 m), using GWT 2.3.0. 
Got the com.google.gwt.core.ext.typeinfo.JClassType exception.
- Tried the same with a GWT 2.1 in dev mode. Worked fine except for the 
following:

12:40:40.159 [ERROR] [hellodatabase] Uncaught exception escaped
java.lang.ClassCastException: com.google.gwt.core.client.JavaScriptObject$ 
cannot be cast to java.util.Date
    at com.google.code.gwt.database.sample.hellodatabase.client.ClickRow$.getClicked$(ClickRow.java)
    at com.google.code.gwt.database.sample.hellodatabase.client.HelloDatabase$2$1$1.onSuccess(HelloDatabase.java:94)

    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
    at java.lang.reflect.Method.invoke(Method.java:597)

But the clickcount went fine. The question would be: do you plan to fix the 
issue, or is there any new workaround we may apply? I definitely understand 
it's quite some deep re-writing of the existing code, being a compatibility 
issue. But as you perfectly already know, it's quite a blocking one.

Please let me know if you need any further detail.

Riccardo

Hi

When do you think there will be a new version, which is compatible with GWT 2.3?
I tried to check out and build it manually as suggested, but I ended up with 
other compilation errors:

Hi

I simply recompiled the sources of the gwt-html5-database project and now it 
works again with GWT 2.4. But now I have to maintain this JAR by myself. Can 
you please upload the recompiled version (1.5.2) to your maven repository?

Regards
Christoph

Facing the same problem, would appreciate an official version that works with 
GWT 2.4

Same problem, I tried to recompile like Christoph did. I did use the 1.5.1 code 
and that did not solve the issue.  please post new official version. 

@ Christoph, could you actually post the jar you created, meanwhile it would 
help guys like me :-)) ?

Benoit

These are not official versions by any means, but are my gwt-html5-database 
builds...

I don't post all the src as I built against a distributed GWT version and not 
against GWT truck, didn't have the time to figure out the ant build completely 
and just hardcoded my paths to the GWT_HOME I was using (= too embarrassing to 
post my build file)

thanks a lot 'big coffee lover' :-) 

Thanks to the provided 'temporary' jar, I could compile successfully .. 

BUT when running the provided example, I get now the same error as Riccardo 
(see comment 7)
java.lang.ClassCastException: com.google.gwt.core.client.JavaScriptObject$ 
cannot be cast to java.util.Date

May be I can develop around and avoid Dates ... but that does not look like 
production quality. Riccardo reported the problem one year ago ... it is 
worrying !!!!!
