Issue with table.insert?

Solar2D General Questions/Discussion

When I get the product information for my In-App-Purchases from Google, I put them in a sorted table using table.insert. This has worked fine in my testing on two different devices, however, I just got a Galaxy S6 and noticed that some of the products are not being displayed in my store. When I looked deeper into it, I found that those products are missing from the sorted table.

I’m really lost with this, could it be that the device or Android version affects how table.insert works? The device that works is Android 4.3, the Galaxy S6 is 5.0.2. Here is some code, and the output from the console:

local validProducts = event.products local invalidProducts = event.invalidProducts local sortedProducts = {} for k, product in pairs(validProducts) do product.title = string.gsub(product.title, "%s%(.+%)","") if shopInfo[product.productIdentifier] then local index = shopInfo[product.productIdentifier].index table.insert(sortedProducts, index, product) print("item "..index.." "..product.title) end end for k,v in pairs(sortedProducts) do print(k, v.title) end

I’d print out the values of product.productIdentifier.  Print out the valid and invalid products before you start working with them and see what’s going on.

Thanks, Rob. All those products were valid. I think the issue is indeed with table.insert.

I changed this line

table.insert(sortedProducts, index, product)

to this

sortedProducts[#sortedProducts + 1] = product

and now all of the items show up as expected, though not in sorted order.

I think I’m going to have to use this way and sort the table myself. I’m not sure why table.insert is failing.

Here is the output
