App suddenly broken after not touching it

[Bluepin01]

Hi, so I took a break from developing a mobile app, and when I came back, it showed this message: 

Now anything to do with these two variables is broken. Basically, they were storage variables for tables, where the user could swap what table was being viewed via a drop down menu. This still works on live, but even if I roll back to a version that works, in editor it is completely broken. When I check the variables they show up as errors. If I try to change the variables for fresh ones, they break too.

Hello @Bluepin01 ,

It seems as if your connection is working on an older version of your datasource. 

Have you tried deleting and re-creating the connections and see how it goes? 

Can you also show us what kind of errors is displayed on the variables? 

Also, if what you're trying to do is storing a table, then why not use a collection instead of a variable?

So the variables are used to switch between multiple different tables, in this case, vehicles. Each vehicle needs an extensive list of details to be filled in, so I'm not sure how I'd have multiple near identical tables on a single form otherwise.  Here's an example of the dropdown menu's code for changing a table. 

Vehicle(n)Var is simply a text value that can be changed on the fly if a vehicle's name needs to be changed.

Just wondering, is it possible to have a gallery of Tables? So I could pick from say, a collection 4 tables, and it would then send me to a sub-gallery of that table's contents.

Yes it is. Although I don't know what the limit is when nesting tables inside tables, but I do know you can work with at least a table inside a table inside a table.

All I really need is a table inside of a table. I've looked it up but results seem to be difficult to come by, so how would I go about doing this? It would likely solve my problem whilst also making it far easier to implement new data when needed.

I believe with a key to identify your nested table should suffice.

Table({Key:"Collection1", Table:Collection1},
{Key:"Collection2", Table:Collection2},
{Key:"Collection3", Table:Collection3},
...
)

Then with a gallery to select the table, simply add a label to display the "Key" property, and the "OnSelect" of the gallery update the variable with the "Table" property of the selected element.

Apologies for the silly question, but where would I go about creating this table?

[WiZey]

To put it simply:

1. Create a new gallery with proposed table:

Table({Key:"LHFTable", Table:LHFTable},
{Key:"KOXTable", Table:KOXTable},
{Key:"JVNTable", Table:JVNTable},
{Key:"UHTTable", Table:UHTTable})

2. Add a label to help identify table to select in gallery:

Text: ThisItem.Key

2. In "OnSelect" of this new gallery:

Set(VehEdit;Self.Selected.Table)

That's what I had in mind, but perhaps you'll find a better approach on the way.

Sorry for such a late reply. When I have a new gallery with the Items set to that table code, it throws an error, saying: "The function 'Table' Has some invalid arguments"
