Reading property from a resource via api, tricky one

[Former Member]

I customer of our company has defined a metadata property

with the following settings:

Property ID: * prop_created

Namespace Alias: *company_namespace

Type: *Timestamp

Key for Label:cm_created

Folder Validity Patterns (csv)/

Document Validity Patterns (csv)/

Property Renderer creationdate

In a project i need to change the value of about 1000 documents over api.

This should normaly be not a problem, but even when the property exists on an document and see the it in the flexible user interface,

it's not possible to read it over the api.

I also tried to iterate over all properties, but this one don't come up.

Any ideas?

Btw, i allready tried it over the IApplicationPropertiesService..Same results here...Property can not be looked up..

Regards,

Thomas

Hi Thomas,

If u want to change the property of 1000 documents, try this [Help|http://help.sap.com/saphelp_nw04s/helpdata/en/44/8d6f90d85c6572e10000000a11466f/frameset.htm]

Hi,

I can't see a reason why this could happen. Try to access for the resource with the property value set (so you can see the value through detail iview) directly:

...
IPropertyName pName = PropertyName.getPN("property_namespace_you_can_see_when_hovering_in_detail_iview", "property_name_from_detail_iview");
response.write("<br>pName:"+pName);
prop = res.getProperty(propName);
response.write("<br>prop:"+prop);
...

what is the output?

Here is the code of the property viewer i created to see all the existing properties

public class PropertyViewerForResource {

	public static void outputProperties(
		IResource item,
		IPortalComponentResponse response) {

		IPropertyMap map;

		try {
			
		
			map = item.getProperties();

			response.write(
				"<font color=\"red\">------------------------Property Viewer MetadatyProperties----------------------<br>");
			response.write(
				"Displaying properties for the following resource:<br>");
			response.write(item.getName() + "<br>");

			if (map != null) {

				IPropertyIterator itr = map.iterator();

				while (itr.hasNext()) {

					String multi = "No";

					IProperty prop = itr.next();
					if (prop.isMultivalued()) {

						multi = "Yes";
					}

					response.write(
						"Property Name:"
							+ prop.getPropertyName().getName()
							+ "<br>");
					response.write(
						"Property Namespace:"
							+ prop.getPropertyName().getNamespace()
							+ "<br>");
					response.write("Property is multivalue: " + multi + "<br>");
					response.write(
						"Property Value: " + prop.getValueAsString() + "<br>");

				}
			}

			response.write(
				"----------------------------End of Output-------------<br></font>");
		} catch (NotSupportedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (AccessDeniedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (ResourceException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		try {
			IApplicationPropertiesService apService =
				GetApplicationPropertyServiceInstance
					.getApplicstionPropertyService();

			response.write(
				"<font color=\"blue\">----------------------------Property Viewer Application Properties----------------<br>");

			IAppPropertyMap mapapp = apService.getProperties(item);

			IAppPropertyIterator itrapp = mapapp.iterator();

			while (itrapp.hasNext()) {
				String multi = "No";
				IAppProperty propapp = itrapp.next();
				if (propapp.isMultivalued()) {

					multi = "Yes";
				}
				response.write(
					"Property Name: " + propapp.getPropertyName() + "<br>");
				response.write("Property is multivalue: " + multi + "<br>");
			}
		} catch (ResourceException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		} catch (WcmException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

Hi,

what you cannot see? The value of the property or all the propertyname/propertyNamespace/value?

btw: you cannot read the property unless it is set to some value...but I suppose you can see it through resource detail iview

Okay, but that will not help in this case.

Cause the change is based on logic in an program.

My question was related to the fact, why i don't see this property over the api.

[Former Member]

Can you see it over WebDAV?

Thomas,

Paste the code that u use to read/set the property
