Preview is not updated after document has been edited

kovalev

I just run into this problem. When I edit a document no matter how: in Microsoft Office or in Google Docs, preview is updated just once. All furhter edits are ignored in spite of the fact they are stored in the document. Log files do not give any clue, no errors mentioned. Can it be a permissions issue? My alfresco Data directory has the following permissions:

I am using dockerized Alfresco 6.1 CE installed on Ubuntu 18.04LTS

Any ideas much appreciated.

Can you please share a step by step description to reproduce the issue?

kovalev

Steps to reproduce:

Log into Share
Create Google document in My Files directory as Test Update.docx
Add some text, for example "111"
Close Google Docs tab
Refresh browser page where document is previewed. The name of the file and contents are updated as expected
Again open this document for editing in Google Docs
Add new line, for example "222"
Close Google Docs tab
Refresh browser page where document is previewed. The previewed contents of document are not changed.

The same situation with thumbnail generation. The only way to get updated preview is to delete corresponding node using Admin tools and then refresh browser page which of course can not be used as a workaround in production.

Here is transformers debug of above mentioned scenario. It is clearly seen that after second editing only Solr index is updated (42) and no other transformer is run to update pdf preview.

@fcorti any ideas how to improve the situation? What logs/settings should I check?

fcorti

At the beginning I thought it was an issue on the client side (ADF?), but after you provided further info I think the issue is on the ACS side.

@EddieMay is trying to find a better suggestion. 😉

kovalev

@fcorti OK, got you. I think I have another connected problem. Sometimes document preview is not shown popping up a message:

Could not load PDF content

So, for some reason PDF preview is not available in spite of the fact that it exists (I can check it with node browser). At the same time if I go for offline editing the PDF preview of the latest version of document is generated and is shown. But as soon as I cancel offfline editing it disappears and system returns to it's previous state - no preview available. I understand that when I go for offline another fresh copy is generated and it brings that "actual" preview, but how to tell the system to update preview of original document - no idea.

May be this description will put more light on this problem.

kovalev

Hello @EddieMay Do you have any any suggestions / questions regarding this issue?

eljuaner

Same issue here with 6.2 version.

afjaber

+1 same issue here with both observations. 1) Preview not updating 2) Error message: "Could not load PDF content"

@kovalev, @fcorti any further insight or assitance available to help get to the bottom of this? Seems like it's impacting many, if not all. Below is our system info.

This is affecting Alfresco content services 7.0.1.3 enterprise as well.So looks likes it was introduced from 6.1 and not addressed at all in both community as well as in enterprise.

I am going to check this on 7.1 and come back
