how to trigger reportFeatureInfo in forEachEntity?

Evan_ReeseEvan_Reese Member Posts: 1,357 PRO
I'm using forEachEntity to iterate over a query. Some of the operations may fail and I want to let the user know when they do. It seems like reportFeatureWarning and reportFeatureInfo don't do anything when inside the loop. I also tried making a boolean variable isError outside the loop to change inside the loop, but inside the loop it's treated as a const, which I can't edit. How might I solve this?

    to get some value from pure function you can define a box container in the outer scope, then make a change to the box value in the function body, call the function and the value will be stored in the box - this is called closure:

    var b = new box("");// declearing box container

    var f = function ()
    {
    //do something
    b[] = "new box value"; // b[] - accessing box inner value
    return "something"; // explicit return - may or may not exist;
    }

    //function call
    f();

    //now box will contain "new box value"
    println(b[]);

    Seem like report functions are only showing message for the first call in the execution flow, the downstream calls are shadowed. Multiple error messages handling is a problematic part of Featurescript because  say even if you collected error messages from the loop in a single string, it will ignore any formatting like line break symbols.

    In my case, I only need one error message if any or all of my functions fail, but I'm still not sure how to set a boolean to true inside the loop and retrieve it outside the loop. With a normal for loop it's not a problem, but I don't think I totally understand forEachEntity.

    Thanks! I've never used a Box type before, so this is really helpful. I got it working.
