Hi,

I'm afraid I only understood the part where you have a library that can only read value in this format: [value].

So where are you trying to add the brackets? In a smartform forms/views, in a K2 workflow, or somewhere else? It'll help if you can provide some screenshots and further elaborate what you are trying to achieve.

A simple method is to put in another control such as a text area and apply an Expression on it to put the brackets around the values from the memo field you need.

Yes i'm trying to add it to view. here is an example (example.bmp). Object view, when button Serialize get pressed generates string - 

{"$type":"Vraa.Div.Client.Reference.ObjectType, Vraa.Div.Client, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null","Any":null,"Id":"2","MimeType":"pdf","Encoding":"xml"}

 this string must be copied to key info view in field Object []. How to copy from one view i find and create that reference with TransferData. But i dont know, how to add brackets [ ]. In KeyInfo view Object [] field, transfered string must be like this:

[{"$type":"Vraa.Div.Client.Reference.ObjectType, Vraa.Div.Client, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null","Any":null,"Id":"2","MimeType":"pdf","Encoding":"xml"}]

Also i have a similar question about transfered info changing. Some methods in library uses differend inputted strings, as example in transferred string we need to remove 

"$type":"Vraa.Div.Client.Reference.ObjectType, Vraa.Div.Client, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"

and left just  

[{"Any":null,"Id":"2","MimeType":"pdf","Encoding":"xml"}]

Thank You for your help 

Hi,

I have to agree with Ziqing on this. The easy way is to have another control on the form or view and use it as a placeholder for the value of the expression, see video link: http://www.screencast.com/t/NpFFNX8lnmhK

1. On the main form. Add a Text Area control (this control can be hidden at runtime).


2. Apply Expression to the control [{string_value}].


3. The transfer action will use the control value from step (2).

Thank you for your help
