undefined index: #maxlength

I created a webform with 4 fields. Three are textfields and one is a date field. The text fields have maxlength and width set for them. Since saving the form, I am getting the following error every time I access the form.
Notice: Undefined index: #maxlength in clientside_validation_webform_after_build_recurse() (line 269 of /var/www/d7dir/sites/all/modules/clientside_validation/clientside_validation.module).
Notice: Undefined index: #maxlength in clientside_validation_webform_after_build_recurse() (line 269 of /var/www/d7dir/sites/all/modules/clientside_validation/clientside_validation.module).

Notice: Undefined index: #maxlength in clientside_validation_webform_after_build_recurse() (line 269 of /var/www/d7dir/sites/all/modules/clientside_validation/clientside_validation.module).

I have this module, webform, webform validation and webform conditional modules enabled.

Here is the html that was generated for the first text field of the form:

<div id="webform-component-first-name" class="form-item webform-component webform-component-textfield">
<label for="edit-submitted-first-name">
First Name
<span class="form-required" title="This field is required.">*</span>
</label>
<input id="edit-submitted-first-name" class="form-text required" type="text" maxlength="25" size="25" value="" name="submitted[first_name]">
</div>

The other textfields look similar. The maxlength property is set. Also can't really tell if the textfields are even the problem, maybe it's looking for a maxlength on the date field(s)? ...

FWIW, I'm using the Stark 7.0 theme while developing the site.
