How to return whether the slot item is virtual

Hi,

I'm trying to access the "isVirtual" property of a Storage.Slot.Item using a script like this:

Storage.Slot.Item item = Storage.system.findItem("");
return item.isVirtual;

However, the command returns the following error.

What is the correct way to do this? Is my synthax correct?

Thanks a lot.

This looks like a FlexScript bug. Unfortunately, I don't know of a workaround. I have added it to the dev list, though.

It may help you to know, however, that if you are virtualizing items, they are all virtualized. They are only unvirtualized if something accesses the "item" property on the slot item:

slotItem.item.assignedSlot = ...;

I don't think items every become unvirtualized unless that happens.

I can increase the priority of this issue, but I can't guarantee that it will be fixed in the next bug fix.

In the meantime you can test if the object stored in the value of the Storage.Slot.Item exists. Here's an example:

clearconsole();
Array slotdotitems=Storage.system.queryItems("WHERE 1");
for (int n=1;n<=slotdotitems.length;n++){
if (objectexists(slotdotitems[n].value))
print (nodetopath(ownerobject(slotdotitems[n].value),1)+" is NOT Virtualized");
else
print (nodetopath(slotdotitems[n],1)+"  IS Virtualized");
}

In the model attached run the simulation forward and then execute the script. The one box is correctly identified as non-virtual.
