looking at roller upgrade again

Maybe a user question (sorry)

Using action like this : action="%{#mainAction}!saveDraft"/> struts 
seems to get the "id" wrong?  ...but the "name" correct.

eg:

<s:set var="mainAction">entryEdit</s:set>

<s:submit cssClass="btn btn-warning"
               value="%{getText('weblogEdit.save')}"
               action="%{#mainAction}!saveDraft"/>

renders:

<input type="submit" value="Save as Draft" 
id="entry____mainAction__saveDraft" name="action:entryAdd!saveDraft" 
class="btn btn-warning">


Should be

<input type="submit" value="Save as Draft" id="entry_entryAdd_saveDraft" 
name="action:entryAdd!saveDraft" class="btn btn-warning">

If I try it on my app it does the same thing

<form name="myConfig" id="myConfig" action="/app/myConfig.action" 
method="post">

<s:set var="myConfigzzzzz" value="'myConfig'" />
<s:submit value="%{getText('button.save')}" action="%{myConfigz}!save"  
accesskey="s" />

</form>

renders:

<input name="action:myConfig!save" type="submit" value="Save" 
id="myConfig___myConfigzzzzz__save" accesskey="s">


should be

<input name="action:myConfig!save" type="submit" value="Save" 
id="myConfig_myConfig_save" accesskey="s">
