Hello All,

I have created form with two data sources. I have added one checkbox and textbox which refer the datasource1 (table name : MyTable1) and also added grid which refers to Datasource2 (table Name : MyTable2).

Then write the below code in the create method of datasource2 in the form :

public void create(boolean _append = false)

{

super(_append);

this.forceWrite(true);

}

Also added below code in the validatewrite method of datasource2 in the form :

public boolean validateWrite()

{

boolean ret;

ret = super();

if(MyTable.MyField == "")

{

info("Some validation message");

ret= false;

}

return ret;

}

My issue : When I create new record in grid and do not fill the required fields, then on closing of the form or clicking on the textbox in anywhere in the form, the validation message fires properly (Display validation message one time), but when I click on any checkbox in the form ,the validation message fires two times which should come only once.

I have verified in the call stack, the validatedwrite method gets called two times on clicking the checkbox.

Please see the below screen shots on clicking the checkbox :

Please see the below Screen shot of clicking on the close button :

Hi Nimisha,

You can use the debugger to find out what is causing the execution of the coding.

Hi Andre,

found that the "validatewrite" method call two times automatically from the "LeaveRecord" method of the datasource while clicking on the checkbox but it call one time while clicking on the textbox.

I have not added any customization code in the "LeaveRecord" Method.

public boolean leaveRecord(boolean _forceUpdate = false)

{

boolean ret;

ret = super(_forceUpdate); --- When super() calls , "ValidateWrite" calls automatically.

return ret;

}

Could you perhaps share the call stack for both validateWrite calls?

Actually I meant screenshots of both cases where validateWrite is called. Is the call stack the same in both?

Do you have some code in the modified method of the checkbox (form control or data source field), or in modifiedField method of the table?

By the way, in general you should not write any code if you want to make a field mandatory. Instead, set property Mandatory to Yes in the table field. Or in form data source field, in case it should not always be mandatory, but only on this form.

Thanks for your reply.

I have verified that there is not any code on the modified method of the checkbox.

As per your suggestion , I have set mandatory = yes property of the fields on the form data source/on the table fields and I did the below cases :

Case : 1

1. Remove this line (this.forceWrite(true);) from the "Create" method of the data source

2. Create new line in the grid

3. Not pressing the CTRL+ S

4. Then clicking on the checkbox/textbox/closing the form --- Not generate any validation message

Case : 2

1. Remove this line (this.forceWrite(true);) from the "Create" method of the data source

2. Create new line in the grid

3. Manually pressing the CTRL+ S

4. Generate validation message one time

5. Then clicking on the checkbox/textbox/closing the form -- Not generate any validation message

Case : 3

1. Added this line (this.forceWrite(true);) in the "Create" method of data source

2. Create new line in the grid

3. Manually pressing the CTRL+ S

4. Generate validation message one time

5. Then clicking on the checkbox -- Generate validation message two times

6. OR clicking on the textbox/closing the form -- Generate validation message one time

Hi Nimisha,

You are talking about any checkbox. What checkboxes do you have on the form? Do they belong to datasource 1 or 2? Or are they unbound checkboxes with some x++ coding when you change the value?
