ROO 1.1.3 cannot process the NotNull correctly with reference

[mikeshi]

Hi guys,

I met a problem, the automatically generated controller class cannot process the reference relationship correctly. I can explain it by a simple sample

// Spring Roo 1.1.3.RELEASE [rev 4404ffb] log opened at 2011-05-07 10:23:59
project --topLevelPackage com.mikeshi.bus
persistence setup --provider DATANUCLEUS --database GOOGLE_APP_ENGINE --applicationId mike-bus
entity --class ~.domain.Bus 
field string name --notNull
entity --class ~.domain.Passenger
field string name --notNull
field reference --fieldName bus --type ~.domain.Bus --notNull 
field set --fieldName passengers --type ~.domain.Passenger --class ~.domain.Bus --cardinality ONE_TO_MANY
controller all --package ~.controller
exit

Then I run

 mvn gae:run

and I created the Bus entity firstly, and then I try to create a Passenger, but when I click the save button, it told me that bus field could not be null. I definitely selected the bus which I created firstly.

Is that a bug?

PS: I use the Google Appengine Datastore as my db, and I modified the pom.xml file, updated the version of maven-gae-plugin to 0.8.4 to use the latest version of GAE .

OK, I resolved it by adding

--mappedBy bus

in the passenger field of entity Bus

field set --fieldName passengers --type ~.domain.Passenger --class ~.domain.Bus --mappedBy bus --cardinality ONE_TO_MANY

It seems works well now.

OMG, it was not fixed yet, when I changed the DB from HYPERSONIC_IN_MEMORY to GOOGLE_APP_ENGINE, it happened again. But without mappedBy parameter, it also happened in HYPERSONIC_IN_MEMORY DB.

I begin to hate GAE,

OK, I downloaded the nightly build 1.1.4, and it is fixed in ROO 1.1.4 SNAPSHOT, thanks you all

Now I am expecting ROO 1.1.4 Release on Thurday very very much

Well well, now, I cannot generate the GWT by 1.1.4 Snapshot, the error message is

GWT module's gwt.xml file not found; cannot continue

Please take a look about it. Thanks
