Hi Krishna,

first put a validation check

try{

if{wdcontect.currentContextElement.getamodel()>0.0|| wdcontect.currentContextElement.getamodel()=0.0)

{

-

---

-

---

}

}

catch(Exception e)

{

wdComponentAPI.getMessageManager().reportSuccess("Please enter positive values");

}

Hi Krishna,

Create one value attribute and bind that to a simple type(double) dictionary , in that dictionary give ur min value as 0 and max as per reqd.

if any doubt let me know.

Thanks & Regards

The attribute is "decimal", a built-in type in WebDynpro that translates to Java BigDecimal type. If you do not want to allow a negative value to enter in the InputField you can code a validation function when you submit the data to the server.

Hi,

Try this:

double x = wdContext.currentContextElement().getBigdecimalAttribute().doubleValue();

Refer methods applicable on Bigdecimal here -
