Tabular Model Explorer - measure properties dissapears after change

[Marcin Frankowski]

Hello,

It should be reported as a bug but unfortunatelly PC I use does not allow to login to Microsoft account due to network limitations so I am not able to report it using VS.

Background:

We create dummy calculated tables to group measures. To create such table we use following statement: "=DATATABLE("Dummy";String;{{"1"}})"

Symptoms:

Each time I define or modify a measure (it applies to DAX code as well as to changing properties in Properties tab)in calculated table and accepts this action following happens:

1. Contents of measures table dissapear (the one where measure calculation results are displayed)
2. Contents of Properties tab dissapear
3. Above happens for any measure in my calculated table. So when I click on different measure after modifying one, problem remains as long as I do not use workaround described below.

Workaround:

The only way to get rid of it is to click on any different table or calculated table in Tabular Model Explorer and then back to the original measure. This is very annoying as each time I want to work on measures each action has to be followed by clicking on different table and then clicking on desired measure back again. For example if I want change Format to "Custom":

1. I click on desired measure
2. I change Format property to "Custom" in Properties tab
3. Contents of Properties tab dissapear and I cannot define Format String as it is not visible
4. I need to click on some other table on the model
5. I need to click again on desired measure
6. Now I can set Format Stringa
