Hi Apsy,
You could try something like the following:
// execute the following method when the page finishes loading
dojo.addOnLoad({
// connect the following method to the onChange event on the myFormField DOM Node
dojo.connect(dojo.byId('myFormField'), 'onfocus', {
// find the dijit object associated with myFormField (the INPUT domNode must have a dojoType attribute)
var myFormFieldWidget = dijit.byId('myFormField');
// if the dijit object is found and its value is blank, set its value to the default
if(myFormFieldWidget && !myFormFieldWidget.getValue())
dijit.byId('myFormField').setValue('my default value');
});
})
