    long com_num;
    long com_amount;
    public boolean isPermutation() {
        return isPermutation;
    }
    public void setPermutation(boolean isPermutation) {
        this.isPermutation = isPermutation;
    }
    public boolean isCombination() {
        return isCombination;
    }
    public void setCombination(boolean isCombination) {
        this.isCombination = isCombination;
    }
    public boolean isBoth() {

    }
    public void setCom_amount(long com_amount) {
        this.com_amount = com_amount;
    }
    public void onChange()
    {
        System.out.print("Per is"+isPermutation);

When your boolean property is named isPermutation, the getter is supposed to be named isIsPermutation().

If you rename your property to permutation, then you can leave the getter named isPermutation().

Also note that this getter prefix won't work if your property type is set to Boolean (and the property name is isPermutation). In this case the getter has to be named getIsPermutation().

To summarize:

The getters for boolean properties should start with is.
The getters for Boolean (and other subtypes of Object) should start with get.
No matter the prefix, the suffix of the getter name should be a UpperCamelCased version of the property name.

More info:

boolean property starting with is is not found.

because it has to be `isIsPermutation`. – Konstantin Yovkov Mar 19 '15 at 19:36
i chnaged isPermutation to Permutation but still not working? – TechChain Mar 19 '15 at 19:39
1. Change `isPermutation` to `permutation`. 2. Change the `value="#{userDraw.isPermutation}"` to `value="#{userDraw.permutation}"`. And don't touch the getter. – Konstantin Yovkov Mar 19 '15 at 19:41
Worked like magic.Thanks ... hang on there for answer my more doubts which might coming in. – TechChain Mar 19 '15 at 19:45

When you have another question, start a new thread so that more people can see it. :) – Konstantin Yovkov Mar 19 '15 at 19:46
