Dear Galaxy Users,<br><br>Since I&#39;ve updated my Galaxy version I&#39;m unable to import any dataset from my history into my data library. It returns a message of e.g. &quot;Invalid item id (1464) specified&quot;. <br><br>
I then did a complete new test installation to make sure that this problem wasn&#39;t because of the update. But the error still remains. I&#39;ve included a screen shot that reports the error. <br><br>When a queried the database the dataset id does exist in the history_dataset_association table.<br>
<br>I went through the paster.log file and found the following 
warning message: Unknown library item type: &lt;class 
&#39;galaxy.model.HistoryDatasetAssociation&#39;&gt;.  I&#39;m sure this is the problem and would need to find a way to fix it.<br><br>Does anyone have the same issue?<br><br>Thanks,<br>Gerrit<br>
