Warning: htmlspecialchars() expects parameter 1 to be string, array given

[klas]

When hidden variation is put on select dynamic in multiple mode the following appears, it also always happens in the list module (I presume hidden is forced here):

Warning: htmlspecialchars() expects parameter 1 to be string, array given in .../libraries/cms/cck/plugin/field.php on line 1116

as $value is array here we need to loop it..sth like http://hawkee.com/snippet/8641/

still here, PR to fix this #301

With Seblod 3.10 I can't reproduce this error message, but hidden form is still rendered incorrectly:

<input id="select_dynamicin_multiple" name="select_dynamicin_multiple[]" value="6,7" class="inputbox" type="hidden">

As you can see array values are rendered as single string,

This should be the same as when form is rendered with default variation

<input id="select_dynamicin_multiple" name="select_dynamicin_multiple[]" value="6" class="inputbox" type="hidden"> 
<input id="select_dynamicin_multiple" name="select_dynamicin_multiple[]" value="7" class="inputbox" type="hidden"> 

My PR should resolve this, but it doesn't as value is converted to string somewhere upstream, before it reaches /libraries/cms/cck/plugin/field.php
