Pass info from record to Iframe widget

[Andrew_TND]

Hello all, I'll try and explain this best I can. 

• I've created a portal widget, for security reasons I'm going to call the page "sp/exec".
• To make it easily accessible I have then created an IFrame widget in a dashboard to said widget.

This works all well and good without an issue, however... There's a catch.

• I have a UI action which runs on a "table" to the dashboard which looks like this...
  

  action.setRedirectURL('now/nav/ui/classic/params/target/%24pa_dashboard.do%3Fsysparm_dashboard%3D29f056a11b9ba290408c4156b04bcb94');​

To loosely explain the widget it essentially takes 3 sets of criteria such as the current record id, its parent and the parent of the parent to display data.

All this information exists on the record on the UI action redirect so my question is... Is there a way to pass the current record data through to the widget on the dashboard?

Thanks in advance! 

Andrew
