Re: Unable to get the newly created folder with the getChildren() method, unless wait for a while

[Florian Müller]

Hi Roberto,

That is an Alfresco specific problem and you should ask there.
A hint from the top of my head:
Use "http://<host>/alfresco/cmisatom". The URL you are using is the old 
CMIS URL. It retrieves the children of a folder from the fulltext 
engine, which might not be up-to-date all the time.

Hi,

I'am unable to get the newly created folder with the getChildren()
method. It's worth to note, however, that after the creation I can
confirm the existence of the newly created folder, but on calling
getChildren() this new folder is not returned unless you wait a 
while.
Please see below junit test. The method testCreateFolder fails, but
testCreateFolderWait doesn't fail. Note, I have the cmis client cache
dissabled.

I'am ussing apache-chemistry-0.7.0 against and 
Alfresco-community-4.0.b.

Is that a bug or I'am ussing wrong the client ?

Thank you.
