Hi,

same problem here but with spring classes (not hibernate):
Note: Only first line of stacktraces shown.

Code:

Hi,

I've spent quite a lot of time trying to reproduce this exception:
first I was trying my own test environment
then
started empty project
created exactly the same entities, data sources, DMI, client side (as specified in the first post)
tested with these builds (2012-10-24 and 2012-10-25)
tested with Hibernate 3.6.1, 4.1.7, with both in the class path

Here is server log:

There are two warnings from JSTranslater: they are correct - there is bidirectional association and loop reference is correctly detected.

How can I reproduce this exception?

there are two possibilities to reproduce the behaviour:

1st:

use the hibernate InstrumentTask to enhance the entities. I use Maven so this pom will do the work:

or the 2nd way is to manuallly enhance the order entity the same way as hibernates InstrumentTask will do. I have already postet this enhanced class in post #5

Hi,

I've committed fix for handling Hibernate instrumented classes (cglib and javassist).

You can test it with next nightly build.

Hi,

I created a small grails app that reproduces the issue. It still occurs using the latest nightlies.
To try, download Grails 2.1.1 from here: http://dist.springframework.org.s3.amazonaws.com/release/GRAILS/grails-2.1.1.zip
Installation instructions are here: http://grails.org/Installation
Extract the test project (https://dl.dropbox.com/u/18305668/SGWTIntegrationTest.zip) and copy the following jars from a SGWT Power Distribution into the respective folders:
lib/commons-discovery-0.2.jar
lib/commons-jxpath-1.3.jar
lib/isc-jakarta-oro-2.0.6.jar
lib/isomorphic_assembly.jar
lib/isomorphic_compression.jar
lib/isomorphic_contentexport.jar
lib/isomorphic_core_rpc.jar
lib/isomorphic_hibernate.jar
lib/isomorphic_jpa.jar
lib/isomorphic_js_parser.jar
lib/isomorphic_spring.jar
lib/isomorphic_sql.jar
lib/isomorphic_struts.jar
lib/isomorphic_tools.jar
lib/isomorphic_web_services.jar
lib/gwt/smartgwt.jar
lib/gwt/smartgwtpower.jar
lib/gwt/smartgwt-skins.jar

Open a shell and change into the project�s root folder. Type �grails war� to build and package the app (including GWT compilation). After this is finished, type �grails run-app� to start the app.
After it is completely started, browse to http://localhost:8080/SGWTIntegrationTest/sgwt to start the SGWT component of the application, which consists of a simple layout and a Datasource backed Listgrid.
Create a new record (�New Record�-Button) and enter some value.
The value is persisted correctly on the server, but exceptions as described in previous posts are raised.

Hi,

I'm not sure which version you use therefore please download next nightly build (2012-11-06) for testing.

Now going to your app:
Yes - initially it shows exceptions. After change "inapplicable" to "ignore" it works fine.
Moreover it works with following data source (all fields with "ignore" commented out):

Code:

<DataSource
    ID="SomeBean"
	serverType="hibernate"
	autoDeriveSchema="true"
	dropExtraFields="true"
    schemaBean="com.aCompany.SomeBean"
>
    <fields>
        <field name="id"/>  
<!--
        <field name="version" hidden="true" ignore="true"/>  
        <field name="attached" hidden="true" ignore="true"/>  
        <field name="errors" hidden="true" ignore="true"/>  
        <field name="properties" hidden="true" ignore="true"/> 
        <field name="propertyEditorClass" hidden="true" ignore="true"/>
        <field name="propertyType" hidden="true" ignore="true"/>
        <field name="readMethod" hidden="true" ignore="true"/>
        <field name="writeMethod" hidden="true" ignore="true"/>
        <field name="writeMethodForActualAccess" hidden="true" ignore="true"/>
        <field name="writeMethodParameter" hidden="true" ignore="true"/> 
-->
    </fields> 
</DataSource>

I have entered 1 to ID and "some prop" to aProperty. Here is a log:

Hi Alius,

thanks, it works now without errors :)
The ignore option is not specified here:
http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/data/DataSource.html
Maybe it should be added?

Regards,
fatzopilot

**Isomorphic** · 6 Nov 2012, 13:19

It applies only on the server, so it's (correctly) doc'd only for server reference - here.

**fatzopilot** · 6 Nov 2012, 13:25

Woh, I googled for 'Smartgwt datasource server' and this never popped up on the first pages (but instead the client docs) so I thought these are the relevant ones....
Thanks for the clarification.
