    item.GetValue throws and exception if the property doesn't exist

    it would be better if GetValue returned a null if the property didn't exist. I had to add a try catch around this call to get round this

    You can't check for it being null or empty because it doesn't get that far

    e.g. this doesn't help

    var item = Model.Items.ElementAt(0);
var foo = String.IsNullOrEmpty(item.GetValue<string>("bar")) ? item.GetValue<string>("bar") : "";

    many thanks

    Tom

    Hi,

    this is fixed in the source code on Github from a commit on 24th July, I grabbed it from there and it did solve the problem.

    Hi there,

    I know that this question is pretty ancient by now, but here is my suggested and very simple solution which has resolved it for me when working with legacy Umbraco versions. 🙂 Hope it helps.

    Best, Tom

     public bool LeBlenderHasValue(
    string fieldName, 
    Lecoati.LeBlender.Extension.Models.LeBlenderValue leblenderValue)
{
    try
    {
        var testValue = leblenderValue.GetValue(fieldName);
        return true;
    }
    catch (Exception)
    {
        return false;
    }
}
