When adding a Sensor under dynaTrace, the screen which shows the package browser shows up as empty. The Total Classes shows 113525 and Total Methods 4813172. The box which used to show the packages and classes is empty.
I also tried to search the class by name and was not successful.
When changing the Agent Group Selection you need to click on the Refresh Button next to the drop down box in order for the tree to reload. If after this reload you still dont see anything (pleae also check that your Find Field is also empty) - then I suggest looking in your dT Client and Server Log file to see if there is anything in there that indicates a problem. In this case you may also want to open up a ticket
The above image is after I refreshed. It takes a while to complete but does not show a tree view. Just to check I entered in the file name for searching. Looks like I will have to open a ticket.
