Update property in VaultExtensionMethod

Question

Hi, 
 i have a problem with updating property in VAF extension method. Method was called from UIX, call is not a problem, but if i use this code, nothing happens. Property 1021 still has same value [VaultExtensionMethod("VaultExtensionMethod_VAF", RequiredVaultAccess = MFVaultAccess.MFVaultAccessEditAllDocs)]
 private string TestVaultExtensionMethod(EventHandlerEnvironment env)
 { 
 var PV = new PropertyValue();
 PV.PropertyDef = 1021;
 PV.TypedValue.SetValue(MFDataType.MFDatatypeText, "Change test 123");
 var oCheckedOutObj = env.Vault.ObjectOperations.CheckOut(env.ObjVer.ObjID);
 env.Vault.ObjectPropertyOperations.SetProperty(oCheckedOutObj.ObjVer, PV);
 env.Vault.ObjectOperations.CheckIn(oCheckedOutObj.ObjVer);
 return "out of VAF"; 
 Any help appreciated. 
 Thanks

The input itself is simply a string; what you pass in will be available in "env.Input". 
 So, let's take your example. Let's say that I have this in my UIX application: 
 shellFrame.ShellUI.Vault.Async.ExtensionMethodOperations.ExecuteVaultExtensionMethod(
 VAFVaultExtensionName, // The name of the extension method to execute.
 '{ "Name": "Craig" }',
 function (response) {
 // The output (string) will be in response; show it.
 shellFrame.ShowMessage(response);
 }); 
 This passes a simple JSON string to the extension method. I could then read it and action it as below. 
 [VaultExtensionMethod("VaultExtensionMethod_VAF", RequiredVaultAccess = MFVaultAccess.MFVaultAccessEditAllDocs)]
private string TestVaultExtensionMethod(EventHandlerEnvironment env)
{ 
 var input = env.Input;
 var parsed = (dynamic)JsonConvert.Deserialize(input);
 return $"Hello {parsed.Name}!";
} 
 Note: you should be using "env.Input", not "env.InputParams" as you are in your screenshot. 
 Regards, 
 Craig.
