PRB: Wizstyle Add Button Does Not Add Child Record (168898)

MORE INFORMATION

The WIZSTYLE class library (Wizstyle.vcx) contains many class definitions. There are three class definitions that are used to navigate in tables: txtbtns, picbtns, and verttxtbtns. Each of these classes have an Add button. In a one-to-many table configuration if the field linking the Parent and Child tables is of type numeric, then the Add button, for any of the navigation classes, does not work correctly when adding a record to the child table.

The following steps illustrate the behavior of using the txtbtns navigation buttons class on a One-to-Many form.

Steps to Reproduce Behavior

There are two parts in setting up this example: Part 1 is to create the two tables used in the One-to-Many wizard. Part 2 is to create the One-to-Many form using the wizard.

Part 1 - Create the two tables used in the One-to-Many wizard:

1. Save the following code to a file called Creatabs.prg:

         *** Begin code ***
         CREATE TABLE parent (Char1 C(2),  Id N(2))
         CREATE TABLE child (Id N(2), Value1 N(3), Value2 N(4))
         SELECT child
         INDEX ON Id TAG Id
         INSERT INTO parent (Char1,Id) VALUES ('11',11)
         INSERT INTO parent (Char1,Id) VALUES ('22',22)
         INSERT INTO parent (Char1,Id) VALUES ('33',33)
         INSERT INTO child  (Id,Value1,Value2) VALUES (11,111,1111)
         INSERT INTO child (Id,Value1,Value2) VALUES (11,123,1234)
         INSERT INTO child (Id,Value1,Value2) VALUES (11,134,1345)
         INSERT INTO child (Id,Value1,Value2) VALUES (22,222,2222)
         INSERT INTO child (Id,Value1,Value2) VALUES (22,234,2345)
         INSERT INTO child (Id,Value1,Value2) VALUES (33,333,3333)
         *** End code ***

2. Run Creatabs.prg that creates both tables and inserts values into each table:

Part 2 - Create the 'One-to-Many' Form:

1. From the Visual FoxPro File menu, select New, and then click Form. Click the Wizard button.
2. On the Wizard Selection dialog box, click the One-to-Many Wizard.
   
   
   1. In Step 1, move all the fields from the Parent table to the Selected fields pane.
   2. In Step 2, move all the fields from the child table to the Selected fields pane.
   3. In Step 3, click Next, as the parent.id = child.id is relation is correctly set.
   4. In Step 4, click Next after choosing a form style.
   5. In Step 5, move the Char1 field to the Selected fields pane.
   6. In Step 6, select the Save and Run button, and click Finish.

NOTE: At this point, the Save As dialog box appears. Once a name has been entered, and the Save button is clicked, the form will run.

1. Click the Add button.
2. In the Add Record dialog box, click Add record to child (grid) only, and click the Add button.

NOTE: The wizard-generated code has not added a new record to the grid, nor it is not possible to move the cursor into a blank row of the grid.
