[jira] [Commented] (TAP5-2081) datefield: cannot blank out date value via text input

["Paul Stanton (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-2081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13596852#comment-13596852 ] 

Paul Stanton commented on TAP5-2081:
------------------------------------

Copying the similar implementation from elsewhere in the datefield.js script, adding the following to the "selectDate" function (just before calling "sendServerRequest") resolves the issue.

// If the field is blank, don't bother going to the server to parse!
if (value == "") {
resultHandler.call(this, {"formatted":"", "value":""});
return;
}

> If you select a date via the calendar, and then delete the value in the text field an exception is thrown since the server site method "onParse" does not accept a blank parameter.
> This should instead avoid going to the server for a parse, and set the current value to null.
