[izpack-users] izpack variable issue

[Mandeep Saini]

Hi Carmel,

Try this :
else if (RULE_FIELD.equals(element[POS_TYPE]))
{
    RuleInputField rulef = (RuleInputField) element[POS_FIELD];
    String variable = (String) element[POS_VARIABLE];
    for (int l = 0; l < rulef.getNumFields(); l++) {
  	 value = idata.getVariable(variable + '.' + l);
          if (value != null && value.length() > 0)
          rulef.setFieldContents(value, l)
    }
}

How you are taking the value of port number at run time. if you are 
taking it from user then you must be storing it inside a variable say 
'port' declared in Install.xml.

If we assume that variable name is 'port' then you have to write:
  <field type="rule" variable="AppServerPort">
    <description align="left" txt="" id="description1.text"/>
    <spec txt="Enter web site port:" layout="N:15:5" set="0:${port}"/>
    validator class="com.izforge.izpack.util.NotEmptyValidator" 
txt="Please enter a valid port number"/>
</field>	

and in Install.xml you can define the default value of port variable as 
8888.

I think this will help bcoz its working for me.
