Commented Unassigned: SPCascadeDropdowns give me a "postback error" [10150]

I everyone,
after reviewing the issues which could match my problem, I found [this one](https://spservices.codeplex.com/workitem/10081).

I'm encountering the same issue, and don't find any clue on how to make it works.
The solutions Marc proposed are good on my side.

I'm actually working on SharePoint 2013 site, I have both the right version of jQuery and SPServices for SharePoint 2013 (jQuery 1.9.0 unminified and SPServices 0.7.2).

I'm using this on 2 Lists ("CR Permanence" and "Synthèse", the column used by the function SPCascadeDropsdowns have exactly the same name), I've modified the newform and editform of "CR Permanence" in which I put the SPCascadeDropdowns code below, it's working just fine. However the same won't work with the "Synthèse" list, and I really don't get why.

```
<script language="javascript" type="text/javascript">
$(document).ready(function() {
$().SPServices.SPCascadeDropdowns({
relationshipList: "PlagesHoraires",
relationshipListParentColumn: "Site",
relationshipListChildColumn: "Plage",
parentColumn: "Site",
childColumn: "Plage Horaire",
debug: true
});
});</script>

```

Is there anyone who encountered this problem recently and found a solution ?

Yoann.
