Courier

I have courier running properly from two installs, installing a revision works perfecty, however, doing a comapre and install fails every time. Here's a quick video of what happens, and the error below that:

http://screencast.com/t/wJp8dF3HGCJ6

Object reference not set to an instance of an object.
Error details


System.NullReferenceException: Object reference not set to an instance of an object.

Any ideas on what could be happening to cause this?

Hi Bruce

It looks like either a provider or an item isn't found, could you zip the revision and send me the link to it on pph @ umbraco com ?

Was anything discovered on this issue? I'm also expriencing this when I create a revision on my staging server and the pull it to my localhost. The error occurs on the 'compare and install' screen.

Using Umbraco 4.7.1 and Courier 2.5.

Are you able to spot which item does this? It is usually caused by an item that does not get a ID associated with it, which could mean the xml data from courier could not be read

It seems to do it on different ones. I reran it multiple times and it's on either the Template or a Stylesheet. So if I know it's one of these items, what do I do now?

The situation is that the code on both localhost and staging is almost exactly the same (using source control). The difference is that the databases are not in sync, and I'm using Courier to get my data sync'ed up.

I guess it might be helpful to update the code so that the error handler threw a custom error that included what file it was on when it threw the error.

As an aside, instead of creating a script for the entire system, I've tried to create sub scripts, to only push the document types, etc. The problem with that is that it still includes the dependencies, so even those are bombing.

I started to go through the .courier files and noticed this in the my style.css file. It looks like it's trying to find the images, but they aren't there. Could this be causing the error?

Hi,

I am experiencing the same thing too.

I am using umbraco 4.7.1 and courier Package version 2.5.4.1.

Any updates on this?

Hi Tammy

Yeah, the compare and install ui + apis have been rebuilt for 2.6 so it will be faster and more stable, we're working on getting the last errors ironed out so you can upgrade to this version instead

Hi Per,

I tested 2.6 too, it seem like unstable.

After a package is created and executed, i go to the task manager and select package or execute.

result i see is "Object reference not set to an instance of an object."

So, when will the 2.6 stable version ready?

Regards,

Tammy

here is the step:-

Step 1: At content Setting:
- I selected a document, right click and Select Courier.
- then a window pop Up called "Transfer Item"
- See image 1
- And click Deploy
- then you will see "Packaging your items". See Image 2
- After packaging done, click cancel.
Step 2: goto Courier Section
- I go to "Task Manager" and right hand side will see "Recently processed tasks" and i selected "Packaging"
- here i can see all the files that i selected at Step 1.
- see image 3
Step 3: Go to content Setting:
- I selected a document, right click and Select Courier.
- then a window pop Up called "Transfer Item"
- And click Deploy
- then you will see "Packaging your items"
- After packaging done, click Continue.
- until you see "Extracting Sample" was completed successfully
Step 4: goto Courier Section
- I go to "Task Manager" and right hand side will see "Recently processed tasks"
- and selected the most recent "Packaging"/"Extraction" and error message as shown as below.
- seem like once we see the message "Extracting Sample" was completed successfully in step 3, the "app_data\courier\revisions\" folder has been deleted.
Hope this is clear enough.
