groups.ds.xml breaks init of smartclient

Be sure your post includes:

the SmartGWT or SmartClient version and browser version(s) involved;

SmartClient_SC_SNAPSHOT-2011-11-15

for a server-side problem, the complete logs generated during processing of the request;

This problem has gotten me on two different projects so I decided to post this so it may helps others from spinning their wheels.

If you have a file named groups.ds.xml in the ds path with the contents of
<DataSource
tableName=“groups”
ID=“groups”
serverType=“sql”
>
<fields>
<field sqlType=“bigint” primaryKey=“true” sqlLength=“19” name=“id” hidden=“true” type=“integer”></field>
<field sqlType=“varchar” sqlLength=“50” name=“group_name” length=“50” type=“text”></field>
<field sqlType=“integer” sqlLength=“10” name=“version” hidden=“true” type=“integer”></field>
</fields>
</DataSource>

THe fix for me was to name the file group_names.ds.xml and change the ID=“group_names” as follows

The startup of smartclient or smartGWT will loop and get a stackoverflow. You don’t even have to have the groups datasouce loaded.

To recreate, just create a file named groups.ds.xml and put it in your ds folder. Then try and start the app and watch the serve log.

It will loop with these enteries
