Fluid Position not working properly

Hi Team -

Anyone here implement position fluid ?

We're currently having issues. Are you familiar how the position gets synched into the classic record?

Based on our tracing, we found that sometimes, the code which calls the classic CI is fired. It's in POSITION_DATA_E.POSITION_NBR.SavePostChange.

And when that gets fired, its erroring out in &CI.GET();

what's weird is, that CI only has 1 key, which is position_nbr and when we use the CI Tester in the application designer, it properly shows the data.

Also, there are times when that Classic CI call is not called, i mean POSITION_DATA_E.POSITION_NBR.SavePostChange is not firing at all, but the classic record PS_POSITION_DATA is updated.
