There could be some dialog to warn user, that something goes wrong internally on server, when creating new application (after hitting the Finish button in New Application wizard).

Currently, there is a Perl internal issue on OpenShift Enterprise (internal eng OpenShift instance). The error message is

com.openshift.client.OpenShiftEndpointException: Could not request https://console.itos.redhat.com/broker/rest/domain/jbdstestdomain57/applications?include=cartridges: Unable to complete the requested operation due to: Permission denied - /var/www/openshift/broker/tmp/cache/9A6/BD0/carts_by_feature_perl-5.10.
Reference ID: 2684a1f6b1e513ea44aa7661ff3d0a3e

but this message can be spotted only in eclipse log (also stacktrace). In IDE there is no support to get user know about issue. In better case, after click on the Finish button in OpenShift wizard nothing happen, in worse case there is a short time UI freeze.
