My app creates a new item, and I want to retrieve the key to use in a server script. The data variable returns null though. This is what I have:

function addItem(addButton) {

  var addItemPage = addButton.root;

  if (!addItemPage.validate()) {

    return;

  }

  var props = addItemPage.properties;

  var itemDs = addItemPage.datasource; 

  props.Creating = true;

  itemDs.saveChanges({

    success: function(key) {

      props.Creating = false;

      if (app.currentPage !== app.pages.EditItem) {

        return;

      }     

      var newProjectItem = itemDs.item;

      newProjectItem._loadHistory();

      gotoEditItemPage(newProjectItem._key, true);

      return newProjectItem;      

    },

    failure: function(error) {

      props.Creating = false;

      console.error(error);

    }

  });

  gotoEditItemPage(); 

  var data = app.datasources.ProjectItems.item._key;     

  google.script.run.withSuccessHandler(function(value){       

     alert("Created");       

  }).createDoco(data);

}

This is not neat by any means, but I fixed it by creating a new function:

function addItem(addButton, key) {

  var addItemPage = addButton.root;

  if (!addItemPage.validate()) {

    return;

  }

  var props = addItemPage.properties;

  var itemDs = addItemPage.datasource; 

  props.Creating = true;

  itemDs.saveChanges({

    success: function() {

      props.Creating = false;

      if (app.currentPage !== app.pages.EditItem) {

        return;

      }     

      var newProjectItem = itemDs.item;     

      newProjectItem._loadHistory();

      gotoEditItemPage(newProjectItem._key, true);

      var key = newProjectItem._key;

      value(key);       

    },

    failure: function(error) {

      props.Creating = false;

      console.error(error);

    }  

  }); 

  gotoEditItemPage(); 

function value(record){   

  var data = record;       

  google.script.run.withSuccessHandler(function(value){       

     alert("Created");       

  }).createDoco(data);

 }

}
