Hi dranakan!

It sounds like you have a running workflow and you have some content in the repository, let's say someFile.pdf, and you want to add someFile.pdf to the running workflow.

If so, that's definitely possible. Files are associated to a workflow by virtue of being inside a workflow package, which you can think of as a temporary folder that exists for the life of the workflow. You can use the workflow service to get a handle to the workflow package, then add the someFile.pdf node to it.

Thank you Jeff 🙂

My goal is to add a file from the disk (Upload file) and not to select one file already in Alfresco.
I would like to add the "upload" button (from http://server:8081/share/page/repository) in the workflow forms.

Actually I am looking in the file : WEB-INF/classes/alfresco/site-webscripts/org/alfresco/components/documentlibrary/include/toolbar.lib.ftl
I define a field to use ftl (in share-config-custom.xml) using "control template". The ftl should have the code starting the selector file. https://forums.alfresco.com/en/viewtopic.php?f=48&t=41486#p122981

Hi Umang_gupta,

Update on the 25.05.2012 :
You can find here a sample in 4.0D to do this : http://www.sendspace.com/file/3arndk or http://www.2shared.com/file/-iY4mBWY/2012_05_25_POC_Add_Files_In_Wo.html

How to install


cp -R webapps /opt/alfresco-4.0.dtest1/tomcat/
cp -R shared /opt/alfresco-4.0.dtest1/tomcat/

Change client-debug to true : tomcat/webapps/share/WEB-INF/classes/alfresco/share-config.xml
         <client-debug>true</client-debug>

In Alfresco, create site with name "workflowTest". The file will go here…

Go to Start Workflow, Adhoc Activiti Process and you should see a new button "Upload File(s)"

Thank you to lukasz_turakiewicz.

Hi dranakan,

I have started to test your sample. When a try to upload a document, every time the upload displayed error in the form and the end of the process.

Do you have a tips or anything else to find the solution, because I have no log in share, alfresco, javascrip debugger …) ?
thanks for your help.

Hi Richard,

Check that the user has enough right to write the file (check destination)… Check the destination exists…

Good luck

Hi dranakan,
i am trying to run you sample but finding problems. Do i need to replace the files in the attachment in respective folders or do in need to save them in /extensions??
Please Help.

Robin

Re: Upload file during a wofklow

dranakan — Tue, 22 May 2012 05:40:37 GMT

Hi Robin,

in the zip you have : "shared/" and "webapps/".

Put (add) "shared/" into your "tomcat/shared"
Put (add) "webapps/" into your "tomcat/webapps/"

And add <client-debug>true</client-debug> in share-config-custom.xml

Best regards.

Hi Dranakan,

Many thanks for your constant help.
Sorry but when i deployed the files in the way you told i am getting following error :
Context initialization failed
Error creating bean with name 'schemaBootstrap' defined in file [C:\Alfresco\tomcat\shared\classes\alfresco\extension\bootstrap-context.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.util.ArrayList' to required type 'java.util.List' for property 'preUpdateScriptPatches'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.alfresco.repo.admin.patch.impl.NoLongerSupportedPatch] to required type [org.alfresco.repo.admin.patch.impl.SchemaUpgradeScriptPatch] for property 'preUpdateScriptPatches[16]': no matching editors or conversion strategy found.
Please Help :roll:
Also, once this application successfully deploys where will i be able to see the 'upload file link' ? I workflows i presume.

Thanks a lot !!
Robin

Hi,

I have done some corrections (for 4.0D) and the sample should works better : https://forums.alfresco.com/en/viewtopic.php?f=34&t=42140&p=128862#p128862

Yes, it is possible. You have to change some code… take a look at this file : shared\classes\alfresco\extension\workflow\qs-workflowModel.xml

Good luck

Hi,

I was unable to get this to run in Alfresco-4.0.e. No errors appear in the debug window, just:

15:30:36 DEBUG - Validating field 'file0' is a valid node name
15:30:36 DEBUG - Validating regular expression of field 'file0' using args: {pattern => {}, match => false} ‍‍

but the file upload window reports Failure.

I am not sure if I am missing something, should it be prompting me for a location to put the uploaded file in the repository? I would check the permissions but I am not sure which folder to check

EDIT: immediately after posting I thought again - it seems as though this extension uses the flash uploader. We have had to disable this due to a bug with SSL, firefox and the flash uploader, but it seems that it is used even though it is disabled in share-config-custom. Is there a way to modify this to use the html uploader instead?
FURTHER EDIT: we've re-enabled the flash uploader and it works fine for uploading to the doclib when we access our site by http (rather than https), however we still get the same problem using it in the workflow form
FINAL EDIT: Discovered the issue. I had accidentally created the site testWorkflow to start with, rather than workflowTest. I noticed straight away and used the "edit site details" dialog to fix it, but did not notice that while this changes the site name it does not change the folder name in the Sites directory (that is - the path was still "testworkflow/documentLibrary/") deleting this site then creating it with the proper name fixed the issue.

For the record, it is possible to modify this code slightly in order to have the location the file is dropped be dynamic between tasks/workflows and configurable in a task variable. I can't think of a portable way to provide this (or I would) and it's a longer process than I want to hijack your topic for, but anyone who needs this feel free to PM me and I can walk you through it.

I know you tried this with 4.0.d. I just tried it with 4.2.0 and got the following exception (below) when I upload a file (upload fails). Any ideas?

TIA,

Jim

Cancel that last question - fat fingered the site name

A couple of other observations: is there a way to attach the uploaded files to the current workflow? In the workflow, the siteId is hard coded, how would you pass in bpm_context value?

Thanks for your help.

As far as I can tell the files ARE attached to the workflow, what do you see suggesting otherwise?

jabelleira — Fri, 12 Apr 2013 19:26:23 GMT

I use this and works fine. But now, i have to update to 4.2b, and now it does not work very well. List of files already attached to workflow is empty, do you know what can i modify to get it working in 4.2b??
