Hi Komal,

here is my actions

Hi Hung,

Here you said  "I have a screen local variable to stored list "sub-category" as JSON. ", what is data type of your local variable?

as screen shot. The local variable is "VarTypeOfRMTableAsJSON" with Text data type.

I tried add Expression to show local variable to screen and using Ajax to refresh it after assign.

It worked. I can get correct value in Save action.

Can you tell me why?

I have implemented same thing, you can check here, https://komal-k.outsystemscloud.com/Block_Event/DisplayJSON.aspx click on get value, you will get the value which block has sent to screen then click on save will return the same value 

Kind Regards,

Hi Komal. 

I updated this oml to use editable table then it's not working as expected.

The oml here!

So you want,  

1. Add record in editable table in block, 

2. Click on correct tick

3. Event called and JSON valued saved into Screen's local variable

4. Click on Save - value should be there for some operation

Is this correct?

Yes,

I found other topic here: https://www.outsystems.com/forums/discussion/43894/lost-data-when-notify-data-from-onrowsave-of-edtable-table/.

Check the attached OML if that works for you,

 you can check here as well

I checked on yours environment but it didn't work.

So i added an expression to stored local variable on view state.

Thanks!

Share the clear solution so any one stuck at same will get it from here.

Kind Regards,
