sap.m.table dater loaded twice

Hi,

I have created a master detail ui5 app.

Everything is shown fine, but in the developer tools I can see, that the data of the master page is loaded twice.

As far as I understand, the binding to the sap.m.table loads the data automatically.

Additionally I added an attachPatternMatched event, to reload data when I navigate back from detail page to master page. In this case the data needs to be reloaded.

Is there any best practive, when I need to reload the data of the master page after navigating back from the detail page?

Thanks

Marcus
