Hi Carlos,
Are you seeing any exceptions in your tomcat logs or in your client details window?
If not, I worked with another client that had a similar issue and we were able to resolve it with a combination of using PTF patch 134 for 9.4.2.1 (Spectrum_09.04.02.PTF_9.4.2.134) and changing the model repository to process more reads (Change the following in the
PTF patch 134 has a couple of fixes in it, but it’s the way the backend SS was fixed for the REST API calls that could positively affect this as well. If you would like it, please open a case and request it as we do not post PTF patches to be generally available (we need to verify they do not conflict with previous patches you have installed).
Either way, since you are running 9.4.2.1 I would recommend installing Spectrum_09.04.02.PTF_9.4.2.134 or you can opt to upgrade to 9.4.3 as the fixes are in 9.4.3 as well (if you take the 9.4.3 route, you may still need to modify the modelrepository entry).
