General

Hi, I have imlpemented your package - everyhting works correctly and I can pick the root server folder from the data type definition. However, when I go to a content node that contains the new doctype property to try to set its value, I get a null reference error as follows:

[NullReferenceException: Object reference not set to an instance of an object.]
   TH.FolderPicker.DataEditor.OnInit(EventArgs e) +39
   System.Web.UI.Control.InitRecursive(Control namingContainer) +132

An I missing anythgin? I am using the Umbraco v 4.6.1 (Assembly version: 1.0.4029.25836). I have tried cerating a completel;y new doctype, and done all the usual IIS restarts etc, but cant seem to figure it out. CHeers

Hi Barry

Maybe this package simply (and sadly) is not compatible with 4.5+ version of Umbraco - since it on the package page says it's compatible with v4.x and not 4.5.x I'm afraid it just won't run on newer versions.

I don't think so, but I will take a look right now...

Normally it has to be compatible but it's long time ago as I touched it the last time ;-)

Will dig into it right now

Bug found

Barry would you be so kind to test the new dll and give me feedback so that I can pack it up to a new version?

Just download the dll from here and put it into your bin folder.

hth, Thomas

Hi Thomas, thanks for your help - could you re-upload the DLL please, I am getting a 404 at that link. Cheers.

Right click on the link, and choose "save as"

it's the dll itself so the webserver does not know how to handle the file extension

Ah yes. I copied the DLL but no I am not getting a TH.FolderPicker in the render control list any more. If I go back to the datatype I created using v0.2 of the DLL, it tells me that 'The given key was not present in the dictionary.'

I am taking a look in the DB now to see if I can clean things out, but let me know if you spot the problem. Thanks again.

BTW I noticed that the original DLL is 14Kb but the new one is only 2Kb.

Hi Thomas - still no joy with your package - is there something missing in the DLL? The version on the link is only 1.3Kb whereas the one in the package is 14Kb. If you don't have time please send me the project code to barryfogarty at gmail dot com and I would be happy to contribute a fix.

Hi All,

I am getting saving an invalid .zip file using Save As on the above link. This is exactly what I need for my present project.

If the package no longer works, could someone give me a hint as to how the tree view was displayed in the data type definition, so I may display it possible as a macro?

Thanks in advance,
