Access Control Icons Disappear on map refresh

MIP

I have an access control plug-in that allows me to add my access elements to a map. This works fine and I can control my doors and view the states dynamically on the map until I either close and reopen the smart client or even switch tabs within the smart client. At this point, the icons from the access control system disappear, never to be seen again (well almost never, I am sure on one occasion I managed to get them to show again some how). Attempting to add the same item to the map again gives an error “Failed to insert element on map” (slightly different to the “The selected element is already on the map” error when you try to add a duplicate to a visible element). The camera icons that I have also added to the map are happy and continue to function, I can add more elements to the map from the access control (just not the ones already added) and these will function as well.

This appears to be the same issue as https://developer.milestonesys.com/s/question/0D50O00003J2HtTSAV/door-icon-disappear-if-i-close-and-open-smart-client?t=1515407104296

Smart Client version 2017 R3 (and also the 2017 R3 hotfix provided to allow me to add input and output elements to the map)

XProtect Express Edition running with a 1 year trial license

I think I’m building my plugin against the 2016 R2 SDK version (Video.OS.Platform.AccessControl dated 13/09/16, 07:52)

but no XProtect files are included in the plugin redistributable (i.e. it is running with the installed version)

Seen on 2 separate machines, one clean VM that has only ever had the 2017 R3 installed on it, the other a physical machine that started life as a 2016 R2, this was removed and the 2017 R3 installed.

Nothing obvious in the logs (MIP or Event)

As an aside, I presume the express version is limited to a single map - how do I delete this map and create another?

I can also reproduce the behaviour with the sample access control plugin (Mini system v 11.3.1964.1 11.3a).

Add an access control system plugin via the management application, select mini system and accepting all defaults)

Launch smart client (v11.3a 64 bit, build 6678), add the single door to a map, switch tabs to sequence explorer in the smart client and then switch back to live view and the door that was added has gone.

I cannot reproduce.

I have a hunch but it might be a long shot; does it matter if you are working with a user that is in the administrators role versus a more regular user?

I only have “administrators” configured.

I have just added a second windows user and made them a regular user, adding them to milestone as well. I restarted all services and logged in as the new user

Initially, the text (names) for the items was shown on the map but not the icons. switching to the sequence explorer and back to live then made the text disappear. Cameras and fixed text continue to work as expected.
