Reflection of indicators properties problem

[Jeremytang]

We have customers that have an old installation of our software. When we replace the DLLs via an external installer, and:

1. delete related reflection cache files in the NinjaTrader/cache directory
2. delete temporary DLLs in the custom/Tmp directory
3. programmatically force a recompile on the next open
4. manually recompile on the next open

We still get NT trying to load properties of the older indicator, properties that use classes that no longer exist. Is there a cache somewhere we can wipe, that NT/windows system is keeping of the reflection property information for an indicator?

Oddly enough performing a uninstall, reboot, reinstall consistently fixes the issue.

There may be an indicator template which the user had set as default from the indicator parameters menu.

If this is the case, this information is saved in Documents\NinjaTrader 7\templates\indicators

You should find an xml file with the indicator name which contains these old parameters that are no longer part of your assembly. You may delete this file and that should remove from the system.
