setting default with seed not working for text input field

[black123]

REFs:

1. http://docs.splunk.com/Documentation/Splunk/6.0.3/Viz/PanelreferenceforSimplifiedXML#Form_inputs
2. http://answers.splunk.com/answers/28633/current-user-in-search

input type="text"
Appears to support with "The initial value of the input element. Can be specified by a value returned from a populating search.".

I want a text field that users can input a "username" into. (And have it default to the current user.) However, I am unable to get it to work. Here is what I am doing.
Note: If I do not use the populatingSearch wrapper around the CDATA block then I see the literal CDATA string in the dashboard.
Note: If I drop the seed element then I see nothing.

<input type="text" token="MyLookupUser" searchWhenChanged="true">
  <label>User to Lookup</label>
  <seed><populatingSearch><![CDATA[ | rest /services/authentication/current-context/context | fields + username | dedup username | search username !=splunk-system-user | rename username as user ]]></populatingSearch></seed>
</input>

What am I doing wrong?
What else do you need to know to help me with this "feature"??

[vgenovese]

is for using a search to populate choices for a dropdown or radio inputs.

For a text input, you can set the value with default, but I'm not sure how to set the value of default dynamically. I will research and respond.

A couple of things

1. Text inputs do not support populating search: http://docs.splunk.com/Documentation/Splunk/6.0.3/Viz/PanelreferenceforSimplifiedXML#input_.28text.2...
2. seed supports text or tokens, not search

I don't think you can do this with simplexml only. You could write a javascript extension to help you, would you be open to using javascript?

RE your point #1:
See the table " child elements" in the URL that we both posted.

Specifically:
"
element:

Type: Attribute value

Description: The initial value of the input element. Can be specified by a value returned from a populating search.
"

So, how do the docs say that a Text element does not support a populating search?

They appear to say that a text input supports a seed element (0..1) which in turn supports a populating search.

To be fair my search should always return one value for the seed.

Having same need to set default value of text input field. Anyone know how to do this in sideview?

[snoobzilla]

See this... I am already in sideview, so I expect it to work...

Hum: "use Sideview" ( REF: http://sideviewapps.com/apps/sideview-utils ) UI modules "bolt on" that has a bit odd of a license. (REF: http://sideviewapps.com/apps/sideview-utils/download-full-version-internal-use/ ) To bad it is not LGPL still. 😞

No thanks.

Besides the main issue is that the plunk docs suggest that what I am trying to do should work.

I suspect a bug exists. Either in the documentation, or in the product. What I want is one of the two to change. Yes, I want the functionality, but I can live with an answer of "You can not do that." too. vgenovese is researching. I can wait.

@black123, did you get an answer from Splunk about this?

[black123]

Nope. Still waiting for a solution. ( Well, I have mostly given up on building a splunk based UI to work the way I want it to at this point. )
