Tokens for default value for Select options

[tkcent]

Tokens are not being accepted in the default value field for Select options. You need to click the Manual entry link to unhide the Default value field.

Problem appears to be the #default_value_pattern value, which is using an old token pattern. This affects the grid component as well.

$ diff select.inc select.inc.old

139c139
<       '#default_value_pattern' => '|^\[.*\]$',
---
>       '#default_value_pattern' => '^%.+\[.+\]$',

This is the Drupal issue where this was reported.

@tkcent can you provide a bit more background? And how to test? I'm not familiar with this. I see that the original pattern was added here https://www.drupal.org/node/1007532.

Sure thing. I want to prefill certain components on a webform based on the page query parameters.

Example: https://www.servername.com/survey?color=yellow

If I create a component of type "Select options" and then use the Manual Entry option to specify the key/value pairs and the default value based on the current page query string token it fails.

Example: [current-page:query:color]

The token string does not validate properly and so the default value does not get saved. The #default_value_pattern needs to be updated to accept token strings.
