HI @retool_amateur and welcome to the forum!
Would you mind sharing yoru settings for the text components on the right (with customer info)?
Most likely you are referring to {{table_orders_without_delivery.selectedSourceRow}}. However, as your table has several instances of it (as many instances as rows) which do not render until a given row is expanded, you need to specify which instance of the table should be used. Here's a thread regarding this issue
The way I solve this is using {{table_orders_without_delivery[table1.selectedIndex].selectedSourceRow}}
by using table1.selectedIndex, I can tell the component which instance of the nested table should be used to find the data. Bear in mind though that this will break if:
- you have multiselect enabled for your parent table
- if user selects another row besides the one that it is expanded. What I usually do (which is not always applicable to all use cases) is to apply an event handler to collapse a row that is no longer selected
But maybe this is not the error, please do let me know if the above helps.
