how to add update button to update data into table..?

Hello,

I made you a basic example of a page that can list your Bonita applications, delete the selected one, then refresh the list:

1. So first in the white board drag and drop:

   - a DATA TABLE widget

   - and a BUTTON widget

2. Then create the 4 following variables:
   - refreshTimeStamp : Type = Javascript expression , value = "return function(){ $data.timeStamp = Date.now(); };"
   - timeStamp : Type = String
   - selectedAppId : Type = String
   - urlParam : Type = Javascript expression , value = "return {"timestamp": $data.timeStamp};"
   
3. Then the configuration of the DATA TABLE should be:
   - Headers = Id, displayName
   - Data source = Bonita API
   - URL = ../API/living/application
   - API request parameters = urlParam (as a variable, need to click on the fx button)
   - Columns key = id, displayName
   
4. and finally, the configuration of the delete button :
   - Label = Delete selected App
   - Action = DELETE
   - URL to call = ../API/living/application/{{selectedApp.id}}
   - Target URL on success = {{refreshTimeStamp()}}
   
   
   and normally, this should work. You suppose to be able to list the current applications in the table, and then if you select a line and click the delete button:

• it will call the delete request
• update the timestamp on success
• as the application list URL depends on the Timestamp, the list will be refreshed

Hope this will help you,

let me know if everything is ok.
