Programmatically change column value when its value is set to something else.

Hi Jordan,

It seems like the conditions on your method are allowing that infinite loop. Make sure you are not updating the field value when a "valid" entry. This should be the end of your loop.

To contribute with more details, could you, please, provide the piece of code for the attribute and the method?

Thanks. 

Dear Jordan, 

Firstly, you need to add an if clause to you custom method, which is triggered by column change. Apply the needed condition for the column to set default value. For example,

var column = this.get("Your column");

if (column !== "some value") {

   this.set(column, "default value");

} else {

  //do other logic or return false

}

In this case you won't have a loop. If you will have any issues, you can share your code with us.

Regards,

Anastasia Botezat,

I'll look at my implementation again, but I tried this already and it still resulted in an infinite loop.

You can also try wiring up the blur event on the number field, then fix it to a valid value when the control is exited, rather than when changed. To wire up a blur method, just add to the diff like this: 

{
    "operation": "insert",
    ...,
    "values": {
        "blur": { "bindTo": "onMyNumberFieldExit" }
    }
}

Then, implement your logic in the onMyNumberFieldExit method, this won't have issues with an infinite loop since it won't be triggered until the user leaves the field.
