Well, hopefully you will soon. My plans are to get it up till end of Q2 :) Once I know that everything is working smoothly in my OpenShift cluster, I will provide a tutorial and share the entire configuration. In the meantime I am getting convinced that the combination Teiid, Keycloak, OpenUI5 and Cordova is a perfect match for each startup :)

Regarding the earlyRequests I will try to find some more information. Unfortunately from the logs I can only see that OpenUI5 tries to send a HEAD request. As this is not allowed, OpenUI5 simple skips the preload. Hence, I do not know what would come afterwards.

> When using Teiid together with SAPUI5/OpenUI5 Odata V4 model, batch processing does not work as Teiid rejects the "Accept: multipart/mixed" header. The issue has been described in
> https://developer.jboss.org/message/986421#986421
> It has been stated that Olingo in general does support multipart messages and it was recommended to remove the header from the request.
> https://developer.jboss.org/message/986425#986425
>  Unfortunately this seems to be not easily possible when using the SAPUI5 framework. I addressed the issue in the SAPUI5 forum under the following issue:
> https://github.com/SAP/openui5/issues/2288
> The result of this discussion was, that the header is valid for the send content. As I am no expert in the topic I do not really have an opinion on that. However, 
> https://www.w3.org/Protocols/rfc1341/7_2_Multipart.html
> suggests that the header is required. So I am not sure if it is correct or an error to reject the message. However, if Olingo can process the content, it would be great to have a fix for the accept header, or alternatively a config option to enable handling of the Accept header in a way that Olingo processes these data.
