Fwd: [fw-mvc] Zend_Form - rendering form level errors

Hi all

I'm still seeing this error with 1.6.1.  You can clear it by doing an empty() check (or equivalent) on $errors in Zend_View_Helper_FormErrors::formErrors(), but am I missing something?

Hello again!

I'm sorry to keep pestering the group with Zend_Form questions, but the project I am currently working on makes pretty heavy use of forms, and by trying to do everything properly with Zend_Form, I'm giving the modules and my brain quite a work-out!

My next issue relates to the display of error messages following form validation by various built-in and custom validators.  Rather than display errors next to each form field (which I can do without problems), I want to display a list of errors at the top of the form.  I have added the 'Errors' decorator to my form using a config which starts like this:

<form>

<name>logIn</name>

<class>login</class>

<action>/login</action>

<method>post</method>

<description>Please log In</description>

<prefixPath>

<element>

<prefix>UKTickets_Form_Element</prefix>

<path>UKTickets/Form/Element/</path>

</element>

</prefixPath>

<decorators>

<formelements>

<type>FormElements</type>

</formelements>

<desc>

<type>Description</type>

<options>

<tag>h2</tag>

<placement>prepend</placement>

</options>

</desc>

  <errors>

<type>Errors</type>

</errors>

<form>

<type>Form</type>

</form>

</decorators>

<elements>

<email>

.....

Now, when I render the form for the first time all is well.  However, once the form is submitted and I receive validation errors, the following warning is output (appearing where I would expect to see errors), and no error messages are rendered:

Warning: htmlspecialchars() expects parameter 1 to be string, array given in /var/www/wetbshared /libs/Zend/View/Abstract.php on line 786

With the following stack trace:

Any help greatly appreciated
