[ http://issues.apache.org/jira/browse/TUSCANY-35?page=all ]
Kevin Williams resolved TUSCANY-35:
-----------------------------------
Resolution: Fixed
After talking with Steve B. we decided that the DAS should insist that
datagraph root is passed to the ApplyChanges command. An error is now thrown
if this is not the case.
> Using ApplyChangesCommand on DataObject child (not root) fails silently
> -----------------------------------------------------------------------

> Key: TUSCANY-35
> URL: http://issues.apache.org/jira/browse/TUSCANY-35
> Project: Tuscany
> Type: Bug
> Components: Java DAS RDB
> Reporter: Philip K. Warren
> Assignee: Kevin Williams
> Priority: Minor
>
> When testing DAS, I initially tried to make a change to a child DataObject of
> the root returned from a DAS command. Here is some sample code (substitute
> appropriate DB table/column names):
> Connection c = ...;
> c.setAutoCommit(false);
> cmd = Command.FACTORY.createCommand("SELECT * FROM TABLE WHERE
> COLUMN=:COLUMN");
> cmd.setParameterValue("COLUMN", "val");
> cmd.setConnection(c);
> DataObject root = cmd.executeQuery();
> DataObject childRow = root.getDataObject("TABLE[1]");
> managedServerRow.setInt("INTCOLUMN", managedServerRow.getInt("INTCOLUMN")+1);
> changeCmd = Command.FACTORY.createApplyChangesCommand();
> changeCmd.addPrimaryKey("...");
> changeCmd.setConnection(c);
> // This fails silently - must operate on root DataObject
> changeCmd.execute(childRow);
> If you examine the database after executing the ApplyChangesCommand, you will
> see that the updates were not saved to the DB (and there was no
> Exception/error from executing the command to know that it failed).
> ApplyChangesCommand only seems to work from the root DataObject.
