Hello -
I am trying to use the EO validation frameworks and am a bit confused.
I would like a person to be able to enter either a number, or a
percent with the percent sign.
But then I need to strip this out.
Do I have to create a "string" instance variable or can I somehow use
validatePercentLoad in the EO?
% is a String value, so you must parse the string:
<wo:WOTextField value="$str" />
public String str;
public boolean success;
public WOComponent control(){
try{
success = true;
if(str.indexOf("\u0025") < 0) //No percertage
{
Integer i = new Integer(str);
//do what you want wth the int
}
else
{
String parsedStr = str.replaceAll("\u0025");
Integer i = new Integer(parsedStr);
}
} catch(NumberFormatException e)
{
//raise the exception for the validation
success = false;
}
if(!success)
return null; //you need this for the validation
return pageWithName(null);
}
Thanks,
James Cicenia
