Getting an error after adding fields to my webform.

Me too. Created the form, added name. Added email but that threw one error. Now the whole web site is bonked with

Fatal error: Call to undefined function url() in /Users/Joe/Sites/devdesktop/henriques-dev/docroot/modules/webform/webform.module on line 1847

Me to got a same error. Kindly provide any solution for this issue.

I got error log message like :

Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[HY000]: General error: 1364 Field 'value' doesn't have a default value: INSERT INTO {webform_component} (nid, cid, type, pid, weight, name, form_key, required, extra) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_8); Array ( [:db_insert_placeholder_0] => 1 [:db_insert_placeholder_1] => 3 [:db_insert_placeholder_2] => email [:db_insert_placeholder_3] => 0 [:db_insert_placeholder_4] => 2 [:db_insert_placeholder_5] => Name1 [:db_insert_placeholder_6] => name1 [:db_insert_placeholder_7] => 1 [:db_insert_placeholder_8] => a:2:{s:11:"wrapper_css";s:6:"sdfsdf";s:9:"field_css";s:6:"sfdsdf";} ) in Drupal\webform\ComponentBase->save() (line 274 of /var/www/html/xxx/modules/webform/src/ComponentBase.php).

API change reference:
Use the \Drupal\Core\Url object in place of arrays of route info - https://www.drupal.org/node/2189619
l() and url() are removed in favor of a routing based URL generation API - https://www.drupal.org/node/2346779

When the error happens, check your PHP log and you should see something like this:

)

It was trying to insert an empty 'value' into the database table "webform_component"'s "value" field which doesn't allow empty (Null) values.

I manually checked it to Allow Null so I could proceed on to add components, but its just a temporary workaround, may not even be a solution.
I guess the module maintainer has to provide a fix for this...

Hi,
Am also try to create the forms using webform 8.x.4-dev faced problems on fatal
As per comment #3 i replicated the issue and patched for that.

Some other issues:
1. Can't create webforms when attached to another content types. it always show blank list.
2. Select Options(Select list, Radio or checkbox option) is not exist in drupal 8

If any one Guide me i can help to fix mentioned issues.

The same issue have been reproduced on email component creation
#6 for me is working well

I'm not sure exactly why it's failing testing, but #6 is working to fix the issue with adding email fields to a webform node.

The patch in #6 solves adding email fields to a webform for me as well. I think it just needs to be rerolled with consistent indents. Regardless, it actually DOES work.

Hi,
As per comment #11 i re rolled patch with proper indentation.

Remove extra spacing. And what's the result of simpletest testing on local ?

The patch in #6 solves adding email fields to a webform for me as well.Thanks

Closing to clear out the old Webform 8.x-4.x branch. See #2827845: [roadmap] YAML Form 8.x-1.x to Webform 8.x-5.x.
