Just upload this via the Manage Dashlets section.
It seems that it doesn't matter what radio button I select when in DASHLET_MODE_GETCONFIGHTML, it always seems to store the value of the last radio button in that radio button group.
For example:
- In the Available Dashlets section click the icon for the Demo Dashlet
The Add To Dashboard window appears
Select Home Page from the drop down list
If you click any of the radio buttons it will tell you the value of that radio button
Select radio_one Value A
Select radio_two Value C
Click the Add It button
Now go to the Home Page
You will see the Dashlet that is reporting the values of radio_one and radio_two
Notice that the value for radio_one is B (I selected value A)
Notice that the value for radio_two is D (I selected value C)
