Hi,

I have in my language file this:

$lang['de_DE']['Statistik']['ANDERESAISON'] = 'Andere Saison anzeigen  ';

and then I'm using that:

$filter = new DropdownField('Saisonauswahl', '', $return, '','' , _t('Statistik.ANDERESAISON','Andere Saison anzeigen  '));

after update the generated code is like this:

<fieldset class="top-form">
			<select class=" nolabel" id="CustomSeasonChooseForm__Saisonauswahl" name="Saisonauswahl"><option selected="selected" value="">Andere Saison anzeigen&amp;nbsp;&amp;nbsp;</option><option value="/spielplan-u23/2009/">2009/10</option><option value="/spielplan-u23/2010/">2010/11</option></select>
			<button onclick='changeSeason();return false;'>anzeigen</button>
		</fieldset>

So it's    instead of   

Anyone?

DropdownField doesn't support filling HTML into <select> boxes (see Convert::raw2xml() call in DropdownField->Field()). This is not an i18n issue - try to output the string directly, it should come out as a HTML entity properly.
