[jboss-user] [JBoss Seam] - Re: document.getElementById() problem with JSF/Seam
thx for the reply. It seems you're right based on the view source (HTML rendered) in
IE:
<input id="mainForm:hotels:3:hideme1" type="hidden"
name="mainForm:hotels:3:hideme1" /><span
id="mainForm:hotels:3:bigout">bigout</span>
I don't know why the hidden field's value ("hideme") is not showing
above. val1 is blank and val2 is undefined in the javascript function when I run the app.
I modified the main.xhtml from the seam booking example as a test below:
