How can I remove a master or detail page from SplitApp?

问题

I add a master page by:

splitApp.addMasterPage(sap.ui.xmlview(
  "clientiListMaster",
  "apps.appClienti.master.clientiListMaster"
));

Ok. my app work perfectly!

Now I want remove it from split app.. i try to do it by:

splitApp.removeMasterPage("clientiListMaster");

but after that, if I try to add once again the same page by:

splitApp.addMasterPage(sap.ui.xmlview(
  "clientiListMaster",
  "apps.appClienti.master.clientiListMaster"
));

I have this error:

2014-09-05 17:12:01 adding element with duplicate id 'clientiListMaster' -

What is the problem...?

回答1:

This part:

sap.ui.xmlview("clientiListMaster", "apps.appClienti.master.clientiListMaster")

is instantiating a view and giving it the id clientiListMaster.

You're doing it twice, which is what UI5 is complaining about. Instantiate it once and store a reference to it (e.g. in the controller) and then use that reference (to the single instance) when adding each time.
