How to get updated HTML radio button in Workflow Inbox?
Question
Since I'm so new for workflow, now I'm stuck at on how to get updated radio button of HTML table in Workflow inbox when click decision button.
STEP 1: ln HTML table, the user can approve or reject WBS by checked radio
STEP 2: When user click confirm, then the workflow will update status for each WBS that shown in the table.
Question: On STEP 2 - how can I get the HTML text which updated by user action.
For now I've enhanced SAPEVENTS and using 'SAP_WAPI_READ_CONTAINER' to get HTML container.
However, after check the HTML code, the HTML table is not update to user action.

Here's a minimal program which demonstrates how to get the values of the radio buttons. If the user presses Approve on the first line and Reject on the second line, and presses the button Confirm, the method on_sapevent gets group[1]=approve&group[2]=reject .
(works in something like ABAP 7.40 SP8)

&& '<p><button type= "submit">Confirm</button></p>'
&& '</form></body>'.
