setVariable in CustomCodePanel

[natje02]

I am trying set a variable in a CustonCodePanel during the pre-Install stage. However,  the value of  the variable is blank during the Install phase. Can anyone help? Here is part the code:

@Override
public boolean setupUI(CustomCodePanelProxy proxy)
{
// TODO Auto-generated method stub
this.proxy=proxy;

proxy.setVariable("$TOMCAT_OLD$", "test");

Any ideas would be appreciated.

Thanks!
