select - Tapestry: default value for a dropdown component -

i use following code select-component:

java-class:

@component(parameters = {"blankoption=auto", "model=somemodel", "value=someid",                          "zone=somezone"}) private select demoselect; 

template:

<select t:id="demoselect" /> 

this gets rendered following:

<select id="demoselect" name="demoselect">     <option value=""></option>     <option value="1">first</option>     <option value="2">second</option>     <option value="3">third</option> </select> 

the behavior i'm looking is, option preselected (this should decided in page class). how can configure in tapestry? need tell tapestry render "selected" appropriate option, e.g.:

<select id="demoselect" name="demoselect">     <option value=""></option>     <option value="1">first</option>     <option value="2" selected="selected">second</option>     <option value="3">third</option> </select> 

does suffice alter model (i don't think so), or have extend select-component itself. have found this article, looked quite promising, unfortunately links source codes dead.

there no need extend anything. setting property value before rendering trick:

@property private sometype someid;  @setuprender void initsomeid() {     if (this.someid == null) {        this.someid = this.getdefaultvalueforsomeid();     } }
