[resolved] [Neo4J - component neo4JOutput] Cannot resolve variable

Hello,
In the following tutotial (https://help.talend.com/pages/viewpage. … d=19422945), we can see the index creation on the TNeo4jOutput (https://help.talend.com/images/54/bk-to … utput6.png).
I strictly followed this tutorial and talend said : types cannot be resolved as a variable, __type__ cannot be resolved as a variable, Employee cannot be resolved as a variable.
Do you have any ideas ? I use Talend Big Data.

PS : When will Talend support Neo4J 2.0 ?

Thanks in advance,
Florian

Hi
I think the issue is the lack of "quotes" in the documentation. Talend uses Java underneath so strings need to be surrounded in quotations. Have a look at the following webinar (http://www.talend.com/resources/webinar … l-database). You can fast forward to the demo (around 32:00). If you look closely you will see the index creation panel at 32:45 and see that the name and key are quoted. Those are required, so it appears to be a bug in the doc.
Let me know if this fixes your issue.
Cheers

Hi,
Yes that was the problem smile. Could you fix it in the doc ? ^^
Also, do you have any ideas for the support of neo4j 2.0 ? Because for the moment, it is impossible to create a label on a node unless you hack with the rest API and the component TRest smile
Thanks for the link smile


Thanks,
Florian
