I still have a problem with the rowItemSize attribute of the row list component even after the upgrade. Current version is 7.2.0 build 4091-04. The row list attributes like this one (rowItemSize) can only be set in the script that is used for my component ? I'm not able to override them in the main thread. I am creating the component and after that I want to set the attributes and it's not working

m.homeScreenRowList = m.app.mainScene.createChild(componentsName.SG_ROW_LIST_GRID)
m.homeScreenRowList.id = componentsName.SG_HOMESCREEN
m.homeScreenRowList.rowHeights = getRowDimensions(m.response, false , sgConfig.ROW_MENU_ITEM_SIZE[1])
m.homeScreenRowList.rowItemSize = rowItemSize

RowItemSize is a variable that holds the values for the rowItemSize
Here is the output :

printing row item size from variable
item size is <Component: roArray> =
[
     264
     110
]
item size is <Component: roArray> =
[
     264
     149
]
item size is <Component: roArray> =
[
     165
     247
]
item size is <Component: roArray> =
[
     264
     149
]
item size is <Component: roArray> =
[
     264
     149
]
item size is <Component: roArray> =
[
     264
     149
]
item size is <Component: roArray> =
[
     165
     247
]
item size is <Component: roArray> =
[
     165
     247
]
item size is <Component: roArray> =
[
     165
     247
]
item size is <Component: roArray> =
[
     264
     149
]   

But if I try to print what's in m.homeScreenRowList.rowItemSize I will get only the values that were set when init function of the component ran.This method of changing the rowItemSize attribute worked fine before 7.2.

output:

printing rowList rowItemSize attribute 
 <Component: roArray> =
[
     264
     149
]

I am having really hard time trying to understand your example. Case might be something i am interested in but IDK.
Can you give very specific example "when i do this - it works" vs "when i do that - it doesn't" - and also put them in [ code] [/code] brackets?

I have one component called rowListGrid that extends the rowList component and has the rowListGrid.brs script for it.If I try to set the rowItemSize attribute in the init function of the script ..everything works as expected (m.rowGridConfig is just an associative array holding some constants).. for example

   function init()
    componentsName =                     getComponentsNameConstants()
    m.rowGridConfig =                       getRowGridConfig()
    m.top.visible =                               false

   m.top.itemComponentName =       componentsName.SG_ROW_LIST_ITEM
    m.top.translation =                         m.rowGridConfig.TRANSLATION
    
    m.top.itemSize =                            m.rowGridConfig.ITEM_SIZE
    m.top.itemSpacing =                      m.rowGridConfig.ITEM_SPACING
    
    m.top.showRowLabel =               true
    m.top.rowLabelFont =                 getFontForRowHeader()
    m.top.rowLabelColor =                m.rowGridConfig.WHITE_COLOR
    m.top.rowLabelOffset =               m.rowGridConfig.ROW_LABEL_OFFSET

    m.top.rowHeights =                      m.rowGridConfig.ROW_HEIGHTS
    m.top.rowItemSize =                     m.rowGridConfig.ROW_ITEM_SIZE
    m.top.rowSpacings =                    m.rowGridConfig.ROW_SPACINGS
    m.top.rowItemSpacing =               m.rowGridConfig.ROW_ITEM_SPACING
    m.top.rowFocusAnimationStyle =  "fixedFocusWrap"
    m.top.focusXOffset =                     [0.0]'
end function

But if i'm trying to do this for example in main.brs script or in any other script file that runs under the main brightscript thread, it will not overwrite the value for the rowItemSize that was set in the init function of the rowListGrid.brs...although I have used this approach and worked fine before 7.2

 
    m.homeScreenRowList =                            m.app.mainScene.createChild(componentsName.SG_ROW_LIST_GRID)      ' this is my component that extends the row list component, and please      note that this triggers the init function mentioned above 

    m.homeScreenRowList.id =                        componentsName.SG_HOMESCREEN
    m.homeScreenRowList.rowItemSize =        getRowDimensions(m.response, true , sgConfig.ROW_MENU_ITEM_SIZE)  'this function returns an array with arrays with the dimensions needed  
    m.homeScreenRowList.showRowLabel =   [false, true]
    m.homeScreenRowList.rowSpacings =      [sgConfig.ROW_MENU_MARGIN_BOTTOM] 'just a constant value 
    m.homeScreenRowList.rowHeights =         getRowDimensions(m.response, false , sgConfig.ROW_MENU_ITEM_SIZE[1]) 'returning an array with heights for the rowHeights attribute

[dacian_roman23]

Here is another output for this code

    sgConfig =                            getRowGridConfig()

    rowItemSize =                       getRowDimensions(m.response, true , sgConfig.ROW_MENU_ITEM_SIZE)
    componentsName =             getComponentsNameConstants()
    m.homeScreenRowList =     m.app.mainScene.createChild(componentsName.SG_ROW_LIST_GRID)
    
    print "printing rowItemSize variable" 
    print rowItemSize

    print "-----------------------------"

    print "printing rowItemSize values"
    
    for each itemSize in rowItemSize
        print itemSize
    end for 

    stop
    m.homeScreenRowList.rowItemSize =   []
    m.homeScreenRowList.rowItemSize =   rowItemSize
    stop

In 7.2 .0 - build 4091-04 it looks like I am not able to set a rowItemSize to an array that has more than 3 other arrays in it . I have limited the function mentioned in previous post that creates the rowItemSize values to return only 3 items and everything worked, but if the returned items number is bigger than 3, then setting the rowitemSize attribute fails .I'll have a deeper look

Here's the debugger output

Can anyone help me with a simple rowList example in 7.2 firmware version where rowItemSize attribute is changed dynamically in the main thread ?

Somebody from the small hired army of "evangelists" should be able to help you (where are they when you need one?!).

In the mean time, do these two help?

This will likely get lost in the noise here, but I wanted to give everyone a heads up that in previous builds of my channel "m.top.observeField("visible", "onVisibleChange")" was only firing on, well, a visible change. As of 7.2, this appears to fire during init as well.

Caused a bug in my app, since I wasn't checking the visible state. My bad in the end, but these types of changes in behavior from firmware to firmware can cause issues in apps.

Thanks EnTerr for the links. I'll have a look to see if somehow they can solve my problem. My biggest concern now with this 7.2 release is that I can't be sure if the bugs are from my code, from the firmware or both and it's even harder to test such problems 😞

Here's another strange issue . Trying to set the rowItemSize attribute for the rowListComponent.Below is the printed array that i'm trying to set on the rowItemSize . According to their documentation -
rowItemSize is an array of vector2d (i suppose that a vector2d array is an array containing other arrays .. each array having 2 values, one for item with and one for item height) but as you can see i get a type mismatch error. What is wrong here ? Is this a bug in the firmare ? The documentation has not been updated ?
