How to manage new invoice with items

[Robert Iliuta]

Hallo,


1.) User insert new invoice, and on the same form has the items browse. After insert all invoice details he begin to add items.
After he add couple of items decided to abandon the invoice and press another menu or home page..
Now the invoice was not saved but the items yes. They are orphaned now. The FM doesn't know he abandon the form to delete the child's... How can I solve this in a easy way.


2.) The relation between Invoice and Items are made by a GUID. Now if user insert a new invoice a new guid is generated. Add details to invoice and then begin to add items. After he add couple of items decided to refresh the page (press F5 or from menu) the page refresh and form initialized again and all embeds are called again... this way a new GUID is generated. Now all items are gone because we have new guid.
How can I prevent this?

In desktop mode is easy to prevent this kind of problems but in web... is different )

Also this is a multi user platform.
 
Thank you for any suggestions or new idea!

Regards,
Robert

> write the details to a temp file and only on save, copy them to perm file. I use this technique on one table where I only want the details updated if the user actually clicks the save button.

        Access:POTRN.UseFile()
        If Access:POTRN.Insert()     
          Message('Unable to Insert POTRN')
        End
        p_web.filetosessionqueue(potrn,net:alsovaluequeue)
        ans = net:ChangeRecord
        p_web.SetSessionValue('FormNewDraftPO:Primed',1)

Hallo Kevin,

The code it's not working for me... After open the form and press F5 the form is in insert mode.
Is that all I have to set?

Thanks,
Robert

um, not to be picky but;

>>  After he add couple of items decided to refresh the page (press F5 or from menu

Pressing F5 repeats the last (non ajax) request from the browser to the server.
If you press F5 halfway through entering any form on the internet it's likely to "start again".
Why on earth would they be pressing F5?

>> the page refresh and form initialized again and all embeds are called again... this way a new GUID is generated.

of course. That would be expected - and indeed desired. If they abandoned the form and then returned to it later by doing an Insert, you'd want it to start from scratch.

>> Now all items are gone because we have new guid. How can I prevent this?

Don't press F5 while half-way through entering the form.
I'm thinking that a popup-form is probably better if you are getting this effect because it's not a "page" so wouldn't encourage users to press F5. But if they do then the browser will repeat the last request.

In essence - F5 means "repeat last request" not "refresh page, preserving my current state" if you get what I'm saying.

Hallo Bruce,

I just want to protect if they will do this (just in case) , If they will press to know what to do...

I will try this.

Yes, I understand! )
