topic File upload blocked through behaviour, how to show proper message? in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/file-upload-blocked-through-behaviour-how-to-show-proper-message/m-p/285266#M238396 <HTML><HEAD></HEAD><BODY><SPAN>Hi everyone,</SPAN><BR /><BR /><SPAN>I need to block certain file uploads and show a proper message, which should explain the exact reason why such file was blocked (there could be a number of reasons). I developed a behaviour in Alfresco which works perfectly: every time there's something wrong with the uploaded file an exception is thrown, so the upload fails. Example:</SPAN><BR /><BR /><PRE class="language-java line-numbers"><CODE><BR />….<BR />// If fileName does not start with "TEST", block upload<BR />if (!fileName.startsWith("TEST")) {<BR />&nbsp;&nbsp; throw new AlfrescoRuntimeException("Filename " + fileName + " should start with TEST");&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR />}<BR />….<BR /><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><BR /><BR /><SPAN>I assume the uploads are always done via Flash Uploader, so here are two pictures of the scenario.</SPAN><BR /><BR /><SPAN>Before uploading:</SPAN><BR /><SPAN>[IMG]</SPAN><A href="http://i39.tinypic.com/10wtuoh.png" rel="nofollow noopener noreferrer">http://i39.tinypic.com/10wtuoh.png</A><SPAN>[/IMG]</SPAN><BR /><BR /><SPAN>After uploading a file (with something wrong in it):</SPAN><BR /><SPAN>[IMG]</SPAN><A href="http://i44.tinypic.com/2u8vtia.png" rel="nofollow noopener noreferrer">http://i44.tinypic.com/2u8vtia.png</A><SPAN>[/IMG]</SPAN><BR /><BR /><SPAN>File upload is properly blocked, but the error message I get in the Share panel is something like "Failed to execute transaction-level behaviour public abstract void org.alfresco.repo.node.NodeServicePolicies$OnCreateNodePolicy.onCreateNode(org.alfresco.service.cmr.repository.ChildAssociationRef) in transaction cf03a86a-4eeb-40bb-8ce7-ddd91753c6e7", which is not what I want (e.g. "Filename AAA_001_A.doc should start with TEST").
