tableView params{} arrive void at onRowRender

I don’t understand why the params{} data arrive void at onRowRender.

... function scene:create( event ) btnGroup = display.newGroup() tbV = widget.newTableView( { left = 10, top = 300, height = 180, width = 300, onRowRender = onRowRender, noLines = false, hideScrollBar = false, rowHeight =8 } ) btnGroup:insert(tbV) ... local function txtLog( myTxt ) local options = {} options.isCategory = false options.rowHeight = 10 options.rowColor = { default={0.8,0.8,0.8,0.8} } options.lineColor = { 1, 0, 0 } options.params = {message = myTxt} tbV:insertRow{options} end ... local function onRowRender( event ) -- Get reference to the row group local row = event.row local id =row.index local params = event.row.params row.bg = display.newRect( 0, 0, display.contentWidth, 60 ) row.bg.anchorX = 0 row.bg.anchorY = 0 row.bg:setFillColor( 1, 1, 1 ) row:insert( row.bg ) if (event.row.params) then row.nameText = display.newText( params.msg, 6, 0, native.systemFont, 6 ) row.nameText.anchorX = 0 row.nameText.anchorY = 0.5 row.nameText:setFillColor( 0 ) row.nameText.y = 10 row.nameText.x = 0 row:insert( row.nameText ) end return true end

looking with debug:

    local params = event.row.params

event.row.params is alway = nil

What I’m making wrong ?

Thanks

My guess is the params just used when the thing is created, so they dont appear outside newTableView function?

sorry I didn’t put the function in the correct order, this is the correct order.

The onRender function is correctly called, but inside the params are void.

... local function onRowRender( event ) -- Get reference to the row group local row = event.row local id =row.index -- event.row.params is void local params = event.row.params row.bg = display.newRect( 0, 0, display.contentWidth, 60 ) row.bg.anchorX = 0 row.bg.anchorY = 0 row.bg:setFillColor( 1, 1, 1 ) row:insert( row.bg ) if (event.row.params) then row.nameText = display.newText( params.msg, 6, 0, native.systemFont, 6 ) row.nameText.anchorX = 0 row.nameText.anchorY = 0.5 row.nameText:setFillColor( 0 ) row.nameText.y = 10 row.nameText.x = 0 row:insert( row.nameText ) end return true end local function txtLog( myTxt ) local options = {} options.isCategory = false options.rowHeight = 10 options.rowColor = { default={0.8,0.8,0.8,0.8} } options.lineColor = { 1, 0, 0 } options.params = {message = myTxt} tbV:insertRow{options} end function scene:create( event ) btnGroup = display.newGroup() tbV = widget.newTableView( { left = 10, top = 300, height = 180, width = 300, onRowRender = onRowRender, noLines = false, hideScrollBar = false, rowHeight =8 } ) btnGroup:insert(tbV) ...

Ye, but I dont think the params are saved. They are used to create newTableView and then they are lost.

Why they are lost?

I’m just copying an example from  Corona University.

You can have a look here:

and also here:

http://docs.coronalabs.com/api/type/TableViewWidget/insertRow.html

the ‘params’ field.

so how can you send data to fill in the table? with a global variable?

Thanks
