Hi,

You might want to read this answer Problem refreshing UI after document deletion or this blog entry: [[Q&A Friday] How to Clear UI Selected Documents in Studio]2

I found the cause : using Nuxeo IDE to create operation, I had this annotation parameter on my run method : (collector=DocumentModelCollector.class)

giving the iterable exception above…

As it is the first time I use Nuxeo IDE, I didn't pay attention to this. After removing this parameter, it works fine.

Thanks for replies and sorry for my noob blindness.

Hello again,

In the init phase I have found this exception :

ERROR [org.nuxeo.runtime.model.impl.RegistrationInfoImpl] Failed to register extension to: service:org.nuxeo.ecm.core.operation.OperationServiceComponent, xpoint: operations in component: service:org.nuxeo.inpt.operations.ClearSelectedDocuments

• Failed to register extension to: service:org.nuxeo.ecm.core.operation.OperationServiceComponent, xpoint: operations in component: service:org.nuxeo.inpt.operations.ClearSelectedDocuments (java.lang.IllegalArgumentException: An iterable method must have an argument)

Eclipse doesn't complain about antything, I can't figure out where is iterable method and where to add arguments…

Is something wrong in the extension generated by Nuxeo IDE ? In the blog screenshot, signature is different, there is no “object” elements, while when exporting my operation, I have this entry in Nuxeo Studio registry :

{ “operations” : [ {

"id" : "Seam.ClearSelectedDocuments",
"label" : "ClearSelectedDocuments",
"category" : "User Interface",
"description" : "Clear selected documents list in UI",
"url" : "Seam.ClearSelectedDocuments",
"requires" : "Seam",
"signature" : [ "void", "void", "object", "object" ],
"params" : [ ]

} ] }

Hi,

Thanks for reply. Nevertheless, following blog's instructions and completing with jar deployement into nxserver/plugins directory and nuxeo server restarting leads to following exception when triggering my chain :

ERROR [org.nuxeo.ecm.automation.jsf.OperationActionBean] org.nuxeo.ecm.automation.OperationNotFoundException: No operation was bound on ID: Seam.ClearSelectedDocuments org.nuxeo.ecm.automation.OperationNotFoundException: No operation was bound on ID: Seam.ClearSelectedDocuments

Is there something else to do ?
