VLWeb Validation Errors / Messaging

[mark.civ]

Hi,

I am using VLWeb and am simply trying to validate blank input into name fields. Ultimately I want to provide context specific validation messages to the web page.

Q1.
I have a reusable part that shows person details onto a webpage. I have existing fields and table I have to use. The validation rules are located on the table definition and not each specific field definition (not sure if that matters). When I use .validate as shown below, the rules on the table are not being checked. I assume they should be checked but the blank entries is being returned as true - ok.

Code: Select all

#GivenName.Validate Operation(Update) Table(#PERSON) Valid(#Result1)
#FamilyName.Validate Operation(Update) Table(#MRKPER) Valid(#Result2)

Q2.
Having jumped to the server, I perform an update on the table. When I do, validation errors occur and I can see messages being passed back to the reusable part, where I have also passed back the IO$STS.

Code: Select all

"messages":["Family name must not be blank","Given name must not be blank"],"fields":{"IO$STS":{"type":{"t":"A","l":2},"value":"VE"}}

This isn't particularly useful as it does not relate the messages to a specific field. Is there a method of getting hold of the messages and their related fields from(after) the update command? I have looked through Val_Error settings but am not sure how to get at the message generated and the field it relates to?

Hi

If you use a dialog, all that is handled for you automatically.
For example if you have a web page that uses a dialog:

Code: Select all

Begin_Com Role(*EXTENDS #PRIM_WEB) Theme(#SYS_THEME<MaterialDesignBlue>) Height(560) Width(840)

Define_Com Class(#PRIM_MD.RaisedButton) Name(#Button) Caption('ADD EMPLOYEE') DisplayPosition(1) Left(24) Parent(#COM_OWNER) TabPosition(1) ThemeDrawStyle('MediumSuccess') Top(18) Width(153)
Define_Com Class(#R0116DL) Name(#R0116DL)

Evtroutine Handling(#Button.Click)
#R0116DL.Show
Endroutine
End_Com

and the code for your dialog is:

Code: Select all

Begin_Com Role(*EXTENDS #PRIM_DLG) Height(641) Width(505)

Define_Com Class(#PRIM_MD.RaisedButton) Name(#Button) Caption('Save') DisplayPosition(1) Left(288) Parent(#COM_OWNER) TabPosition(1) ThemeDrawStyle('MediumTitle') Top(56)

Group_By Name(#PSLMST) Fields(#EMPNO #SURNAME #GIVENAME #ADDRESS1 #ADDRESS2 #ADDRESS3 #POSTCODE #PHONEHME #PHONEBUS #DEPTMENT #SECTION #SALARY #STARTDTE #TERMDATE)

Evtroutine Handling(#Button.Click)
#COM_OWNER.ValidateEmployee
Endroutine

Mthroutine Name(ValidateEmployee)
If (#COM_OWNER.Validate( Update #PSLMST ))
#COM_OWNER.Save
Endif
Endroutine

Mthroutine Name(Save)
Define_Com Class(#PSLMSTSM.Save) Name(#SaveEmployee)
#SaveEmployee.ExecuteAsync PSLMST(#PSLMST) Status(#IO$STS)
Evtroutine Handling(#SaveEmployee.Completed)
If (#IO$STS = "OK")
* Signal Event(EmployeeSaved)
#COM_OWNER.Close
Else
#VF_ELTXTX := ""
For Each(#mensaje) In(#SYS_MSGQ.Messages)
#VF_ELTXTX += #mensaje.Text + (10).AsUnicodeString
Endfor
#sys_web.Alert Caption(#VF_ELTXTX)
Endif
Endroutine
Endroutine
End_Com

You will see it will highlight the fields with error in the screen with no additional interaction needed.
The Alert I put at the end is in the case the server module have additional validation (for example in
a begincheck/endcheck or particular stuff or other kind of errors like duplicated key)
