As you might expect. I'm at eh last 10% of the project an I've run into a nasty snag.

Here’s the scenario:
I have 2 stacks. Main and MeasurerLib.
Main has an on PreOpenStack script that populates a datagrid on card 2 of the MeasurerLib stack.

Card 1 of the main stack has a button that opens the MeasurerLib stack to card 1 as modal.

The MeasurerLib stack has 2 cards.
Card 1 has a set of fields that the users can populate. It also has 2 buttons. A Save button that populates the datagrid on card 2 with the information from the fields and an edit button that navigates to card 2 where the datagrid lives. There is a cancel button on card 2 that navigated back to card 1.

The on PreOpenStack script works fine. The datagrid on card 2 of the MeasurerLib stack gets populated.

The problem is that if I navigate to card 1 of the MeasurerLib stack from the button on card 1 of the main stack and fill in the fields and click the save button. The row of the datagrid that was populated from the stack script isn’t recognized. The new text is simply populated right over top of the existing text. So there are 2 lines of text I the same row.

However, if I first navigate to card 2 of the MeasurerLib stack where the datagrid is and back to card 1 before filling in the fields and clicking the save button viola, everything works as predicted.

Long story short, what command is sent to the datagrid when I navigate to the card it’s on that make the row recognized??????
I've tried this on card 1 of the MearurerLib stack but it blows away the headers. Grrrrrrr

on PreOpenCard
dispatch "resetList" to group "ListOfMeasurers" of card "DataGrid Holder" of this stack
end PreOpenCard

Thanks a lot for any help.

Can you please post a screenshot and (some) of your scripts?

This is the datagrid with the text on text. Card2 of the MeasurerLib stack. Card1 of the MeasurerLib stack.
on preOpenStack -- main stack script
put StackPath (filename of this stack) & "Measurer_Trax.ini" into tPath_Trax

Hmmm, nothing obvious, need to gues...

How "long" are your rows that you display in the datagrid?

I remember that I had a "too long" (to display) line (> 32k or 64k?, not sure anymore)
which cause the SAME inconvenience as you are currently experiencing.

The rows only have six columns with not a lot of data. I appreciate you looking at this Klaus. I'm going to be working on another project involving 7 stacks each with at least 2 datagrids that will be populated in a similar fashion. If I run into the same problem I don't know what I'm going to do. This is a persistent and reproducable problem. I hope the guys at RunRev are loking at this. hanks again Klaus.

Hmm, I see... What line exactly from your longish script above causes the double lines of text on top of another?

Hi Klaus,
The stack script works fine. It's the save script. If I just fill in the fields and click save, without first navigating to the card where the datagrid lives, I get the double text.

Thanks,
Tom

does it work if you do first navigate to that card and then update the datagrid on that card?
If yes, the this may be a bug?

Yes, if I navigate to the card where the DG lives then back to the first card where the fields and the save button are, it works. But I have to do that every time I want to edit the DG.

Thanks,
Tom

Hi Tom,

sounds like a bug to me, I'd write to: support@runrev.com
