Accesing custom persistent property from script

Question

Hello
I´m trying to add a custom persistent property to documents and layers, but when I try to access it from the script, always have error 55 saying that the object -layer/doc- doesn´t accept that property.
I defined the property within the VersionedScriptElementInfo section of the project fr file:
     resource VersionedScriptElementInfo(1)
             kFiredrakeScriptVersion, kCoreScriptManagerBoss, kWildFS, k_Wild,
             Property
                 kIsLocked,
                 p_isLocked,
                 "Item is locked",
                 "Item is locked",
                 BoolType,
                 kNoAttributeClass,
             // Connects this plug-in's events and properties to scripting.
             Provider
                 kCustomLockScriptProviderBoss,    // provider boss ID
                     Object { kLayerObjectScriptElement },
                     Object{ kDocumentObjectScriptElement },
                     Property{ kIsLocked, kReadWrite },
p_isLocked is defined using a free id:
     enum CustomScriptProperties
         p_isLocked = 'LVLk'
and kIsLocked is also declared:
     DECLARE_PMID(kScriptInfoIDSpace, kIsLocked, kCustomPrefix + 0)
Both, kDocBoss and kDocumentLayerBoss, have an addin declaring the custom lock implementation:
     IID_ICUSTOMLOCK,kCustomLockImpl,
Script code is something like this:
     app.activeDocument.layers.item(0).isLocked=true;
Do you know what´s happening?
Is it neccesary to add custom data on new doc/layer responder before accesing it?
Any ideas will be welcome
Regards

Answer 1

I think I have it!!!
Custom property name must be as declared witin the third field.
In this case, it must be itemIsLocked.
Sorry for such a trivial question.
