UniQuery - Form Inherited - SetConnection ACCESS VIOLATION UNIDAC160.bpl

Hi, i think it's a bug of 5.x bug.

using: 5.0.2 Trial

Replicate Error:

1) Create Form1 with a uniQuery1;
2) Create Form2 as Inherited from TForm1
3) Put a UniConnection on Form2
3) Set Form2.uniQuery1.Connection to UniConnection (from Object Inspector)
4) Save unit2.pas and close form2.
5) ReOpen form2 : Access Violation in Unidac160.bpl : Do not open .dfm !

If you remove

Code: Select all

  inherited UniQuery1: TUniQuery
    Connection = UniConnection1
  end
form unit2.dfm

then all is ok again.

Best regards

ims
