Query regarding initialization of jsp form 


Hi,

I am facing the following issue with regard to jsp form initialization by
struts
When a primitive data type such as int or double is used in the form bean ,
the corresponding jsp shows the
form elment initialized to 0 or 0.0 as the case may be.
	 How do i prevent this from happening ?

However if the form bean attribute carries a valid value (say 5 or 6.56 etc)
, then the same must be displayed on the jsp.


Let me enumerate with an example

Suppose the form bean look like this

	FromBeanA.java
	{
		double age ;

		public void setAge(double age)
		{
		this.age = age;
		}

		public double getAge()
		{
			return this.age
		}
	}

--- And the jsp has the following

<html:form action="/xyz.do" >
--------------
-----------
<!-- here form bean is assumed to be appropriately configured -->
Age = 	<html:text name="FromBeanA" property="age" />


<html:form/>

then  the display of the jsp will look like this

		Age = 0.0

I do not want 0.0 to appear


Thanks in advance,

	Prakash

Thats why its better to always use Strings for the form properties and
convert to the appropriate type for the business logic back in the action.
