Hi
Take a look a the code

<t:inputText value="#{bean.val1}">
<f:validator validatorId="validate"/>
</t:inputText>

<t:inputText value="#{bean.val2}">
<f:validator validatorId="validate"/>
</t:inputText>


public void validate(FacesContext arg0, UIComponent arg1, Object arg2) throws ValidatorException {

if (cond1)
validate1(arg0, arg1, arg2);

if (cond2
validate2(arg0, arg1, arg2);

}

private void validate1(FacesContext arg0, UIComponent arg1, Object arg2) throws ValidatorException {

// validation code here for val1

}

private void validate2(FacesContext arg0, UIComponent arg1, Object arg2) throws ValidatorException {

// validation code here for val2

}


Now I need to know the condition cond1 and cond2 whether it can be given for different inputTexts. So i do not need to have different classes for different text boxes. How do I identify which text box is being called in the validate method since I have the same Id for both. Can this requirement be done like this or is there any other way ? Please help

Hi Augustine,
I personally haven't tried this with plain JSF. You might want to give it a try:
1. Provide ids to your inputText tags (assuming this is not a constraint for you)
2. In your validator check the component.getId() value against the id's of tags in step 1.

 
It is sorta covered in the JavaRanch Style Guide.
