I’ll file this as a bug/feature request but another (really unfortunate) issue with widget.newTableView:
Only one can be used at a time.
If you try to use multiple newTableViews, even in seperate lua files using seperate Render Events, Corona will stitch them together. At best (using a mask) one view will just be a white box. At worst, you’ll see the views transport from one to another.
Why you might want to use multiple views : Especially with iOS5, there seems to be a trend on iPad devices to use small listviews in pop-up rather than pickerviews. (ie: in Safari if you click on a multi-page website review, the list is a listview, not a pickerview. Good example of this is Anandtech)
I gather this might be a vulnerability of fully exposing the render cycle, but I thought it initially could have been solved by simply using different render events.
Fun code sample ahead, if you think you might have a workaround. 
[code]
local widget = require “widget”
– Create the First List.
local myList = widget.newTableView{
width = 310,
height = 270,
top = 200,
left = 100,
}
– Event Listener for the TableView.
local function onRowTouch(event)
local row = event.target
local rowGroup = event.view
if event.phase == “press” then
if not row.isCategory then rowGroup.alpha = 0.5; end
elseif event.phase == “release” then
if not row.isCategory then
row.reRender = true
print(“You touched row#”…event.index)
end
end
return true
end
– Render Event for the TableView
local function onRowRender(event)
local row = event.target
local rowGroup = event.view
local text = display.newRetinaText(“Row #”…event.index, 12, 0, nil, 18)
text:setReferencePoint(display.CenterLeftReferencePoint)
text.y = row.height * 0.5
if not row.isCategory then
text.x = 15
text:setTextColor(0)
end
rowGroup:insert(text)
end
– Create the List rows.
for i = 1,100 do
local rowHeight, rowColor, lineColor, isCategory
if i == 25 then
isCategory = true
rowHeight = 24
rowColor = { 70, 70, 130, 255 }
lineColor = { 0, 0, 0, 255 }
end
if i == 45 then
isCategory = true
rowHeight = 24
rowColor = { 70, 70, 130, 255 }
lineColor = { 0, 0, 0, 255 }
end
myList:insertRow{
onEvent=onRowTouch,
onRender=onRowRender,
height=rowHeight,
isCategory=isCategory,
rowColor=rowColor,
lineColor=lineColor
}
end
– Create the Second List.
local myList2 = widget.newTableView{
width = 310,
height = 270,
top = 500,
left = 100,
maskFile = “popupMask.png”
}
– Event Listener for the TableView.
local function onRowTouch2(event)
local row = event.target
local rowGroup = event.view
if event.phase == “press” then
if not row.isCategory2 then rowGroup.alpha = 0.5; end
elseif event.phase == “release” then
if not row.isCategory2 then
row.reRender = true
print(“You touched row#”…event.index)
end
end
return true
end
– Render Event for the TableView
local function onRowRender2(event)
local row = event.target
local rowGroup = event.view
local text = display.newRetinaText(“Row #”…event.index, 12, 0, nil, 18)
text:setReferencePoint(display.CenterLeftReferencePoint)
text.y = row.height * 0.5
if not row.isCategory2 then
text.x = 15
text:setTextColor(0)
end
rowGroup:insert(text)
end
– Create the List rows.
for i = 1,100 do
local rowHeight2, rowColor2, lineColor2, isCategory2
if i == 25 then
isCategory2 = true
rowHeight2 = 24
rowColor2 = { 70, 70, 130, 255 }
lineColor2 = { 0, 0, 0, 255 }
end
if i == 45 then
isCategory2 = true
rowHeight2 = 24
rowColor2 = { 70, 70, 130, 255 }
lineColor2 = { 0, 0, 0, 255 }
end
myList2:insertRow{
onEvent=onRowTouch2,
onRender=onRowRender2,
height=rowHeight2,
isCategory=isCategory2,
rowColor=rowColor2,
lineColor=lineColor2
}
end
