Hi people
I have a bean with Labels and textfields together. The data inside the textfields is a Vector of Objects. I need to be able to get the textfield to accept different datatypes depending on other dependencies.How do I get the textfield to accept :
1. A String datatype only
2. An Integer datatype only
3. A Date datat type only
4. An IPAddress formatted value
Thanks
Meghna
