Several times now I've encounter a bug where  had a TGrid with an assigned TDataSet.  I switch to a different form, add a new TDataSet, and suddenly the old TGrid on the old form is updated to use my new TDataSet for no apparent reason.

In all three situations, I wasn't editing the Grid when I switched forms.  I don't know why it does this.

Do these forms/datasets share the same name ?

The only time that EWB performs any type of "fixup" on these types of references is when forms/databases/request handlers are loaded, and the fixups are performed according to the name of the owner form/database/request combined with the name of the component being referenced.

No, they don't at the current time.  But obviously they were all named TForm1 or TDialog1 when they were created.
Maybe to avoid confusion, EWB should name forms TForm2, TForm3, etc at create time or prompt the user for a form name - because yes that is a different annoyance when you run your project and multiple TForm1's or TDlalog1s exist.

Something seems to happen at compile time that causes the change.  You compile, then saddlery the datasets are wrong or datafyield.

It happened again.  This time I was paying attention.

I had a Form1.  I created a new form, which it defaults to Form1.  Then compiled, realized my mistake of having two form1s, and renamed the 2nd Form1 to FormNewUesr.  But Form2 had a TGrid which referred to the Dataset on Form1, now switched to FormNewUser, even though the Dataset was on real Form1..
