asynchronous processes and variables and errors

_psx_ over 4 years ago

Lets see example

var global gV;

function classA_setThemeParams(colour)

{

gV= col;

....

}

function onLayout(dc)

{

classA_setThemeParams();

}

function onUpdate(dc)

{

for(i...)

{

//something external fe. backgroung call classA_setThemeParams during the loop

drawables(i).draw(dc);//samewher in drawables there is dc.setColor(gV,gV); <----------------------------------- from time to time error, why?

}

Error Name: Symbol Not Found Error

Error Name: Invalid Value

Why this happen?

gV should be handle an point to value

this example show that

- sdk makes "local var" from global instead of taking value from def every time

- during operation = sdk change handle to object

after implementing flow

x = getProperty()

x.toFloat()/x.toNumber()

there has been no error for 2 days (maybe users stop using my wf )

part of this data are saving obtaining it previous from json coming from webrequest so maybe there is problem for system to valid good type but still on sim data are saved in correct type

aftrer changing flow

view.onUpdate() -> drawable.draw() -> view.onBD()

view.onUpdate() ->view.onBD() -> drawable.draw()

there is no error for 7 days, but of course maybe people have stoped using my wf
