New record can not display default value.

[dcs]

Setting a default value can be configured via the DefaultValue option in the DataSource Model configuration. My Code would look similar to this:
.DataSource(dataSource => dataSource
   .WebApi()
   .Create(create => create.Action("Create", "Home"))
   .Update(update => update.Action("Update", "Home"))
   .Read(read => read.Action("Read", "Home"))
   .Model(m => {
        m.Id(id => id.Id);
        m.Field(f => f.Name).DefaultValue("test");
    })
)
After I click on the "Add new record" button, the new row can display,but Name cann't display "test". why?

Hello,

I am afraid that with our last official release we introduced a regression bug that affects applying default values with some fields (in this case string type of fields). Currently we are working on fixing this problem with highest priority and I will let you know in this thread when the fix will be available in the latest internal build. 

In the meantime you can sue the BeforeEdit event in order to apply a default value as shown below: 

.Events(e=>e.BeforeEdit("onBeforeEdit"))
<script>
    function onBeforeEdit(e) {
      if(e.model.isNew()){
        e.model.ContactName = "Test";
      }
    }
</script>

Thank you for understanding.
