component getting items from array before its needed
I have an app where a user puts in the required info into text inputs inside a titlewindow pop up and it sends the data entered into a datagrid. This first time when I call for the popup and enter info it works fine. Here's the problem: the next time I call the component pop up and click anywhere on the popup, including textInputs, the first the item in the array is automatically entered into the textInput where the user is supposed to enter the data themselves (BTW this textInput is also a autocomplete component).What I want is nothing to entered into textinput until the user inputs the data themselves. I've been tweaking with it for hours and im stumped. Any suggestions would be highly appreciated.
Here's the code: (this is main page)
