how auto populate jsf edit forms

[festo]

Hi guys,

how do I get a form to auto populate in jsf/jsp when the user clicks
the edit button.
That is if there is a radio button that had been previously checked, to
have it correctly checked, if a drop down item was selected , to have
that item selected?
Please help

In the bean, have something along these lines:
-------------------------------------------------------------------------------------------
public boolean isMyRadioChecked()
{
return myRadioChecked;
}

public void setParam(String value)
{
myRadioChecked = true;
// your code here
}

private boolean myRadioChecked;
-------------------------------------------------------------------------------------------
then in your page, have:

<input type="radio" name="param" value="value" ${bean.myRadioChecked ?
"checked" : ""}>

so when myRadioChecked == true, your radio button code will turn out
like this:

<input type="radio" name="param" value="value" checked>
