I have a sql property binding error on my Root Container with no message.  
I have gone through everything associated with the Root Container and i can not find it.  
No errors while in Designer this (see below) only shows up on the client screen.

I have already converted all my queries to Names Queries.  
What should I be looking for? My software is ver. 7.9.4

I figured this one out. My Named query was using a custom property that gets its value from the selected cell on a table component. My property binding was this -

```
try({Root Container.Table.data}[{Root Container.Table.selectedRow}, 1], 0)

```

When nothing was selected the 0 was throwing an error when no rows / cells were selected.  
I changed it to a generic value and now it works

```
{Root Container.Table.data}[{Root Container.Table.selectedRow}, 1], 200)

```

Now I would like to learn how to include a "Fall Back" into Named Queries.  
See this post -
