DynamicDSGenerator breaks other DS

Hi,
until now I used xml generated DS. But now I need to add a DS which is going to have a dynamically set table name. So I decided to create a DynamicDSGenerator.

public class PersonalFolderDSGenerator implements DynamicDSGenerator {

    @Override
    public DataSource getDataSource(String s, DSRequest dsRequest) {
        DataSource dataSource = null;
        if(DataSourceEviLoader.getPersonalMessagesDsId().equals(s)) {
            StringBuffer stringBuffer = new StringBuffer();
            stringBuffer.append("<DataSource ID=\"personalMessages\" progressiveLoading=\"false\" requiresAuthentication=\"true\" schema=\"dev\" serverType=\"sql\" tableName=
...
                    "</DataSource>");
            try {
                dataSource = DataSource.fromXML(stringBuffer.toString());
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return dataSource;
    }

I'm adding the generator in one of my configuration startup services

DataSource.addDynamicDSGenerator(new PersonalFolderDSGenerator());

afterwards I'm loading the new DS like all my previous once

DataSource.load(personalMessages, new Function() {
			@Override
			public void execute() {
					callback.execute();
			}
		});

So far so good. But when I add the generator my IDACall is having problems creating an RPCManager instance. Which I use to authenticated users.

RequestContext context = RequestContext.instance(this, request, response);
				RPCManager rpc = new RPCManager(request, response);
				rpc.setAuthenticated(true);
				rpc.setUserRoles(Lists.newArrayList(roles));

the fallowing exception is thrown

it seems that my "transactionNum" is empty and can't be thrown to a Long.

No server logs attached because it doesn't come to the call. An error is returned in the response.

Without the generator everything seems to be working fine.
