If someone else got a similar problem and the workaround is not satisfied, I just found the correct way to set it programmatically in Java: 
 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>OdaDataSourceHandle dsHandle = designFactory.newOdaDataSource("Data Source", org.eclipse.datatools.enablement.oda.xml");
dsHandle.setPropertyBinding("FILELIST", new Expression(dynamicDataSourceString, null));
</pre>
 
dynamicDataSourceString is the String which should be added in the xml here (after "<expression name="value" type="value">"): 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
