Hello there!

I'm with an error when I try to check-in an edited document on Google Docs [Alfresco Community 2017-07].

This is the first lines of alfresco.log:

org.springframework.extensions.webscripts.WebScriptException: 01270019

And this is the error message I get on Alfresco Share:

Could anyone help me to solve this error?

Regards!

I have the same problem on alfresco 5.1.g

[juliodobkovski · Accepted solution]

Hey Paolo! How are u?

I think I've found the solution, all you need to do is to specify 2 parameters in alfresco-global.properties.
I've added this lines at the end of configuration file:

googledocs.enabled=true
integration.googleDocs.idleThresholdSeconds=<specify in ms the time to concurrent doc lock>

In my Alfresco I added:

googledocs.enabled=true
integration.googleDocs.idleThresholdSeconds=5

If this does not work for you, try another parameter:

googledocs.enabled=true
googledocs.idleThresholdSeconds=5

It works smooth for me.

Hi @juliodobkovski,

Thanks for updating your thread with the answer that worked for you - very helpful! Let's hope it works for @PaoloP too.

Have a nice day

Tengo el mismo error, agregué las líneas indicas y no funciona. Nos complica trabajar en equipo. Tengo instalado Alfresco 5.1. Su ayuda urgente. Gracias

[EddieMay]

Hola @edtalla,

Cuando dice que agregó estas líneas en alfresco-global.properties, ¿reinició tomcat?

[edtalla]

Si reincie el tomcat.. pero igual seguió persistiendo el error.

Hi @edtalla,

Vale. Comience un nuevo hilo - ya que esto está marcado como resuelto, podría ser ignorado. Incluya su version y entorn.
