java.lang.IllegalArgumentException: Value for key (property name) can't be put into node

Hi everyone,

                     i am trying to add/update new/existing property with value to asset metadata and when i say resolver.commit(), it results in following exception

When i reprocess the same asset for creating/updating same metadata property, it works well. Please suggest any improvements here.

    This happens when the map already has key with same name. to update you have to remove it and then put new values like map.remove(propertyname); map.put(propertyname,value);resourceResolver.commit();

    Hope it helps.

    Have you seen that the exception contains this line:

    > javax.jcr.version.VersionException: Cannot set property. Node [path/to/asset/jcr:content/metadata] is checked in.

    You need to check out that node first to continue to save() properties. Not sure why it has been checked-in without being checked-out.

    Hi Jörg Hoh,

                            yes, i could see version exception as follows,

    Caused by: javax.jcr.version.VersionException: Cannot set property. Node [/content/dam/path/to/asset/jcr:content/metadata] is checked in.

    I am wondering who is checking in this asset. Is there any way to figure out?

    Thanks & Regards,

    Radhakrishna.

    Hi,

    that's not immediately visible. I remember cases where this happened for pages on "pagemanager.createVersion()", could be for assets the same. In general, node.checkin() and node.checkout() are part of the versioning. Maybe this can help you to track down suspect log entries.

    Try Asset API. Asset ("The Adobe AEM Quickstart and Web Application.")

    Asset is created by AssetManager and can be retrieved either via AssetManager or by adapting a asset Resource to an Asset.

         eg:

         // to create an asset

         AssetManager assetManager = resolver.adaptTo(AssetManager.class);

         Asset newAsset = assetManager.createAsset("/path/to/asset/document.pdf");

         // to get an existing asset

         Asset asset = assetManager.getAsset("/path/to/asset/document.pdf");

         // to get asset by adapting

         Asset asset = resource.adaptTo(Asset.class);

    Asset properties can be retrieved or set by adapting it to a ValueMap.

         eg:

         // to get Asset properties value map

         ValueMap map = asset.adaptTo(ValueMap.class);

    Hi Yadav Brijesh,

                                thanks for your suggestion. I would look to understand your suggestion using Asset API. What advantage are we going to get when compared to Resource. Can you please help putting your view here and how that helps this problem to be solved?

    Thanks & Regards,

    Radhakrishna.

    When working with AEM - if there is a corresponding API - like Asset Manager API, Tag Manager API, etc, you should ways use these strongly types APIs when programmatically working with AEM.

    Here is URL to the Javadocs - "The CQ5 Quickstart and Web Application."

    ** MAY MAKE A GOOD Ask the AEM Community Session**

    Thanks for letting me know, smacdonald2008

    Here is the code snippet for the same,

    String customValue = "update";

    Resource assetRsc = resolver.getResource("path/to/asset/metadata");

    if(assetRsc !=null) {

        ModifiableValueMap properties = assetRsc.adaptTo(ModifiableValueMap.class);

         properties.put("custom_property", customValue );

         // some more properties to be set here

         saveToRepo(resolver);

    }

    private void saveToRepo(ResourceResolver resolver){

    try {

    resolver.commit();

    } catch (PersistenceException e) {

    logger.error("Exception while saving changes :", e);

    }

    }

    I hope this helps understanding. Please let me know, if any other information is required.

    The code looks good. What is the exact value you are trying to put?

    Hi rmahendr

                              the values(create/update/delete) i use are of string type. The second property takes string[] type values.

    Thanks & Regards,

    Radhakrishna.
