JSDO: cannot pass parameter from one jsdo session to another jsdo session

This question is answered

hi 

from the following code  i have to call to get data from these 2 function in sequence once i get the lvcDefaultSite  from getDefalutSite function I need to use lvcDefaultSite  as an input for the getProductionLine.

now i cannot pass parameter from function getDefalutSite  to getProductionLine

1. JSDO execute function asynchronously. so both function fire an event onAfterFill when data filled complete. So  this will not happen in sequene.

2.JSDO will execute both function at the same time so i will never get value to pass to getProductionLine function.

Do anyone have an idea to solve this issue?

  • Hello,

    The simplest solution would be to call getProductionLine() from within onAfterFilliccCtrl().

    You could also rearrange your code and chain the Promises.

    The code that you posted shows both sessions being created for the service. You can just create one session for the given service. This would also simplify the code and make the solution clearer.

    I hope this helps.

    P.S.: Just in case you have not noticed it, there is a typo in getDefaultSite().
