PowerApps Editor loses its mind

[SukieP]

It's happened to me more than once.  I'm editing an app for more than 4 hours.  I click Ctrl-S frequently - every time I make an important change.  I am weary and accidentally delete a control.  Hundreds of little red error circles appear.  There is no Un-Do.  There is no Control-Z.  I close my session without saving and reboot.  I restore a recent Save- it is no good - full of errors.  The only decent version I have is from 4 hours ago; I know I saved more recently.

Hi @SukieP ,

I cannot speak for Ctrl-S, but save frequently using File > Save and make version notes of where I am up to. These are always there if I have to roll back, Also I have found Ctrl-Z restores deleted controls (and anything else you have done in reverse order, so careful how many times you select it) - the only thing if it is a card in a form it ends up at the bottom of the list as the last control put in the form.

Thanks Warren.  For me, Ctrl-S and Ctrl-Z work, until it they stop working.  It seems there is a time limit on PowerApps maker sessions, or maybe my browser fills up its cache.  I'm going to have to set a timer and restart my browser every few hours to prevent losing my work.

Hi @SukieP ,

Yes - the Session Expired is another subject and why I save frequently - I just wish that is was based on no activity time rather than session time.

Hi Warren,

It just happened to me again, and I figured out the cause.  This app is uses SharePoint list with many columns, and multiple forms.  I understand now that SharePoint defaults are ignored by PowerApps, so all of my number types were blank.  I was seeing the blank errors in Monitor once I enabled verbose, but it wouldn't show me what controls they were tied to, and I was on a different form/tab so the arrangement of the error circles looked random. 

Now I've set the default for the datacard values to

If(varFormMode = FormMode.New, Text(0,"[$-en-US]#,##0"), Text(Parent.Default,"[$-en-US]#,##0"))

and the errors are gone.  I have SOOO much to learn!

Hi @SukieP ,

SharePoint Defaults should not be ignored in Power Apps - I use them regularly and they always come up if the relevant control when the form is set with NewForm(FormName)

Hi @WarrenBelz,

Thank you so much for setting me straight.  I was using ResetForm.
