How to pass values from a multiselect dropdown through a Redirector module and prepopulate a dropdown on 2nd page

[cmak]

With the following code:

<module name="Redirector">                                                                                                    <param name="url">VG_Single_DUT_Test_Data_v1</param>                                                                                                    <param name="popup">True</param>                                                                                                    <param name="arg.Weight_Select">$Weight_Select$</param>                                                                                                 <param name="windowFeatures">scrollbars=yes,width=1000px,height=1000px;</param>                                                                                                </module>

Weight_Select is a variable from a multi select dropdown. Therefore, the value is 'weight="3" OR weight="2"' for example.

When I pass this through to the Redirector, the other page cannot use this to prepopulate a dropdown for weights. It seems like to URL loader takes in the parameters such as "Weight_Select=2&Weight_Select=3" in order to prepopulate dropdowns. Is there an easy way to prepopulate my weight dropdown in my second page with the redirector?

If this cannot be done, I suppose I could construct my own link.

For Redirector keys, all you have to do is follow the normal convention of using $foo.rawValue$ always for links, redirects and human-readable headers, and using the $foo$ key itself only for cases where it's being fed directly into the Splunk search language.

This will work for multiselect Pulldowns as well as single-selection Pulldowns, and indeed it will note the array-valued selection and you'll end up with values in the URL like ?Weight_Select=value1&Weight_Select=value2&Weight_Select=value4.

And in the target view, when URLLoader sees that value, assuming there's a multiselect Pulldown module with a name param of "Weight_Select", it will be able to prepopulate itself to exactly those values when the page loads.

This point, about when to use $foo.rawValue$ and when to use $foo$, is called out as being an important point on the main docs page for using Redirector and URLLoader - go to either "Key Techniques -> linking from view to view -> intro", OR go to "Module Documentation > The URLLoader and Redirector modules". Both of those links actually go to the same page. Note the third bullet item in the "Notes" section.
