World Creator sample request

[Johnka2]

Is there any sample on world creator. i have looked at existing documentation and only functionality is demonstrated but no info on how to set it up and existing demos are too old to run on current version.

using a sample from old expand demo "WorldCreatorTester.Win" v18.2.7 i get this error after upgrade to 21.2.6

Exception occurs while initializing the 'Xpand.ExpressApp.WorldCreator.WorldCreatorModule' module: Cannot handle the "Xpand.Persistent.BaseImpl.PersistentMetaData.PersistentClassesModuleInfo" type. To address this error, add an appropriate Object Space to the AdditionalObjectSpaces collection (see http://docs.devexpress.com/eXpressAppFramework/DevExpress.ExpressApp.CompositeObjectSpace.AdditionalObjectSpaces).

is there any sample from current versions

[apobekiaris]

only packages from the xaf.expandframework.com are tested on each build, so no I do not have a sample but this does not look like an error. did u follow the suggestion?

[Johnka2]

yes followed the suggestion. but application does not reach that far. this happens at startup

[apobekiaris]

post your sample using nugets and latest version please

[Johnka2]

wc.zip

[Johnka2]

this is the wc demo upgraded to 21,2.6

[Johnka2]

i have checked this and it works with dx 19.2.7 something changed in dx 21.2 that breaks it

[apobekiaris]

WC is like u run a 2nd Xaf app b4 the main app Xaf introodcued this exception as it seems in between need time to patch it. If you have the time to do it I can review your PR

[Siratigui]

you can register PersistentClassesModuleInfo inside your module constructor with the line below:

WorldCreatorTypeInfoSource.Instance.ForceRegisterEntity(typeof(Xpand.Persistent.BaseImpl.PersistentMetaData.PersistentClassesModuleInfo));

[apobekiaris]

what this means? is it kind of fix ?

[Siratigui]

yes we faced the same error while ago.

Hi,

Do someone successfully started worldcreator? We have same error as Johnka2 with 21.2.601 version. Sirarigui suggestions does not help also.

[arnzuk]

Hi, apobekiaris,

Are you going to fix worldcreator? It does not work with 21.2 version

[apobekiaris]

PR are totally accepted however I cannot spend resources, to investigate possible patches unless there is a sponsorishp for the task.

[apobekiaris]

according to changes in #940 WC should be functional now

[apobekiaris]

maybe this can also be included in the actuall WC module and not in your project mdules? If can someone test and confirm happy to add this line as well.

WorldCreatorTypeInfoSource.Instance.ForceRegisterEntity(typeof(Xpand.Persistent.BaseImpl.PersistentMetaData.PersistentClassesModuleInfo));

what I mean add in WorldCreatorModule build test and report back

WorldCreatorTypeInfoSource.Instance.ForceRegisterEntity(AppDomain.CurrentDomain.GetAssemblyType("Xpand.Persistent.BaseImpl.PersistentMetaData.PersistentClassesModuleInfo"));
