Hi Isomorphic,
I am trying to fetch data from a datasource into a TableView Widget.
Here is the datasource definition, stored in the ds directory:
And here is the code to fetchdata and fiil the tableView:
I have set the resthandler and datasourceloader servlets in the web.xml as follows:
[code]
<servlet>
<servlet-name>RestHandler</servlet-name>
<servlet-class>com.isomorphic.servlet.RESTHandler</servlet-class>
<init-param>
<param-name>defaultDataFormat</param-name>
<param-value>json</param-value>
</init-param>
<init-param>
<param-name>wrapJSONResponses</param-name>
<param-value>false</param-value>
</init-param>
</servlet>
<servlet>
<servlet-name>DataSourceLoader</servlet-name>
<servlet-class>com.isomorphic.servlet.DataSourceLoader</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>RestHandler</servlet-name>
<url-pattern>/isomorphic/RESTHandler</url-pattern>
</servlet-mapping>
<!-- DataSourceLoader requests -->
<servlet-mapping>
<servlet-name>DataSourceLoader</servlet-name>
<url-pattern>/isomorphic/DataSourceLoader</url-pattern>
</servlet-mapping>
[code]
I am using the smartgwt mobile jar file which creation date is May 10th 2012.
When I try to fetch data I get the following exception:
which it seems that the from config method of the datasource class has a bug on casting a record to a datasourcefield.
Could please tell me if I am using the datasource load correctly and if its a bug, o otherwise I am doing something wrong?
Thanks in advance,
Pablo

Code:
Prueba.xml

TableView tv = new TableView();
tv.setDataSource(dsList[0]);
tv.fetchData();
