Loading a saved XML file in VB gives errors

[archashukla]

I have created a small view using VB and saved it's generated XML file.
When I try to load the same file for editing the GUI it gives errors.

Please find the server logs below

There are certaing XML parse and validation error in the logs.
But, since the same file worked when I created the GUI I don't understand what is the exact problem.

[Isomorphic]

There are warnings but no errors or exceptions here. If there's an actual error, post the full details.

[archashukla]

I am not getting any exceptions

The only thig which I am getting is
{
"/DataSource":{
recordPath:"/DataSource",
ID:{errorMessage:"Field is required"}
}
}

Can you please help me in resolving these warning.
I do not understand even these warning.I guess some field attribute is required which I have not provided?

[Isomorphic]

Don't worry about the warning. The question is what error you're seeing. Does the screen load? Does an error dialog come up? Is there a JS error? What's in the client-side logs in the Developer Console?

These are the things to post *every time*, otherwise, you will just be asked for them, and you will waste your own time.

[rkewlani]

Even I am getting the same warning and Only column names are getting displayed on browser and data is not loading.
