I have a requirement that I have to show all the attachment files from previous task to next task form. and I have found the solution that I should download external action "VT Get List Item Attachment" , but I did not find any link of it.From where I can download external action "Get List Item Attachment in Base64" to get the attachment from all the tasks.Please help me to solve this issue.. thank you.
thanks for the reply...
It works properly but whenever I click on the attachment link, it shows the error "A potentially dangerous Request.Path value was detected from the client (." So I can not download the attachment in next task.... so what is the solution of it.???
If you are talking about what you are receiving after the implementation of Vadim's UDA, it sounds like you are not supplying a correctly formatted url to the Base64 object call. I would check out what you have as the Attachment URL.
I have implemented this and it works a treat. Thanks Vadim!
I am attaching files in one task and in next task that attachments are displayed. While in next task's form , I am getting this error while clicking on that attachment link.
I have used foreach loop and in Attachment_url, I am getting url of one file (for example, http://abc/sites/sitecoll/Lists/Service TL/Attachments/805/call web service.txt)
While showing previous attachment in next task form, url of attachment contains additional part of task form url(for example: http:/abc/sites/sitecoll/Lists/Service%20TL/%7Bhttp://abc/sites/sitecoll/Lists/Service TL/Attachments/805/call web service.txt).
Here," http:/abc/sites/sitecoll/Lists/Service%20TL/%7B " is additional to my link.Because of this additional link I am getting above error.
Please help me in this.
I have followed this link collect task attachments in list item and show all attachments in next task and attached files on one task and trying to show in next.
