Xrm.Page.getControl fails after applying Service Update 1 for Microsoft Dynamics CRM Online 7.1.1

Hi,

I have a contractdetail quickView attached in incident form and other quickviews to see some interesting info in one sight.

I used Xrm.Page.getControl to acces to it's field values.

E.G.:

var remain = Xrm.Page.getControl("coberturas_coberturas_contractdetail_allotmentsremaining");

So remain.getAttribute().getValue() was an integer.

Now Xrm.Page.getControl("coberturas_coberturas_contractdetail_allotmentsremaining"); is NULL

I lost access to elements coming from this and other quickviews.

I begin to happen just after applying the UPDATE.

I have not found any related or known issue about it.

Any help please?

Thank you.
