Question

I try to integrate dotcmis and alfresco into my application.
When creating my unit tests, I face this issue :
– I set up my test environment by deleting “myfolder” if any
– I create back myfolder and put a document into it

then I try to find the document :
– The first time (when myfolder does not exist before), Search returns 0 results
– Next times, when myfolder exists before and is deleted by my test setup, I get an exception :

Apache Chemistry OpenCMIS - runtime error
HTTP Status 500 - <!--exception-->runtime<!--/exception--><p><!--message-->Node does     not exist: missing://missing/missing(null)<!--/message--></p><hr noshade='noshade'/><!--    stacktrace--><pre>
org.apache.chemistry.opencmis.commons.exceptions.CmisRuntimeException: Node does not exist: missing://missing/missing(null)
at org.alfresco.opencmis.AlfrescoCmisExceptionInterceptor.invoke(AlfrescoCmisExceptionInterceptor.java:80)
at ...

When I go to Alfresco, the document exists.
It seems that the folder and document are not yet disponible for query, but why ?
If I put in comment the test environment init, the document is found

Maybe I do something wrong but what ?

Here is my code :

[TestMethod()]
[DeploymentItem(@"Files\SearchTest_1", @"Files\SearchTest_1")]
public void SearchTest_2()
{
    string myfoldername = "myfolder";

    // Session creation
    var p = new Dictionary<String, String>();
    p[SessionParameter.User] = _userName;
    p[SessionParameter.Password] = _userPassword;
    p[SessionParameter.BindingType] = BindingType.AtomPub;
    p[SessionParameter.AtomPubUrl] = _serverUrl;

    var session = DotCMIS.Client.Impl.SessionFactory.NewInstance().GetRepositories(p)[0].CreateSession();
    session.DefaultContext.CacheEnabled = false;
    var operationContext = session.CreateOperationContext();
    operationContext.IncludeAcls = true;

    // Delete and create back folder and document
    // /*
    DotCMIS.Client.IFolder rootFolder = this._testSession.GetRootFolder(operationContext);
    DotCMIS.Client.IFolder myFolder = null;
    Dictionary<String, Object> properties = null;

    // Le dossier de destination des tests existe-t-il ?
    var myFolderExists = rootFolder.GetChildren(operationContext).Any(child => child.Name.Equals(myfoldername));
    if (myFolderExists)
    {
        myFolder = (DotCMIS.Client.IFolder)session.GetObjectByPath(String.Format(@"/{0}", myfoldername), operationContext);
        myFolder.DeleteTree(true, DotCMIS.Enums.UnfileObject.Delete, true);
    }

    properties = new Dictionary<String, Object>();
    properties[PropertyIds.Name] = myfoldername;
    properties[PropertyIds.ObjectTypeId] = "cmis:folder";
    myFolder = rootFolder.CreateFolder(properties);
    rootFolder.Refresh();

    myFolder = (DotCMIS.Client.IFolder)session.GetObjectByPath(String.Format(@"/{0}", myfoldername), operationContext);

    FileInfo sourceFile = new FileInfo(@"Files\SearchTest_1\SearchTest_1.pdf");
    properties = new Dictionary<String, Object>();

    properties[PropertyIds.ObjectTypeId] = "cmis:document";
    properties[PropertyIds.Name] = sourceFile.Name;

    using (var fileStream = sourceFile.OpenRead())
    {
        var contentStream = new DotCMIS.Data.Impl.ContentStream();
        contentStream.MimeType = "application/pdf";
        contentStream.Stream = fileStream;
        contentStream.Length = fileStream.Length;
        //this._testSession.CreateDocument(properties, this._testSession.CreateObjectId(myFolder.Id), contentStream, null);
        DotCMIS.Client.IDocument createdDocument = myFolder.CreateDocument(properties, contentStream, null);
    }

    // */

    // Recherche
    string query = @"SELECT * FROM cmis:document WHERE cmis:name = 'SearchTest_1.pdf'";
    var results = this._testSession.Query(query, false, operationContext).ToArray();
    Assert.AreEqual(1, results.Length);
}

Are you using Alfresco 4.0 with Solr for indexing? The Solr index is eventually consistent, this means that it can take a while (up to 15 seconds in the default configuration) for updates to show up in search results.

If you need updates to show up immediately you could switch to Lucene as the indexing subsystem.
