Using multiple-value variable in canvas button post

Hi,

I’m having troubles to configure a repeated canvas panel with a button.

Repeated panel uses multiple-value varaible called “ids” to create several canvas panels in a row. These panels have a button that post data in json format and this data should include the id of the generated panel.

So far, I can use ${ids} in panel title but not in JSON post.

Example 1:
{"id":"${ids}"}

Result 1 is:

Object
id:"{1,2,3,4}"

Example 2:
{"id":"${ids:json}"}

Object
id:Array[4]
0:"1"
1:"2"
2:"3"
3:"4"

In both examples, the problem is that the variable in post is getting all selected values but not the specfic for that panel.

I tried using it in the URL but the result is the same.

Any suggestion?

Thank you in advnace,
Carlos
