Maximum decimal input text in richfaces

[sars]

Hallo All,

Please help me. I have a problem with decimal. I need to check it for maximum length is 4 digit with coma in the middle. And 4 digit is maximum value. So suppose I insert 4444 in my input text, it will be automatically convert into 44.44 .So data that will store in database is 44.44. And if I insert 44444, it will change to 44.44. If I input 44447, it will be converted into 44.45.

I tried use this way

<h:inputText id="gradePoint"

                                                                      value="#{myBean.gradePoint}" size="5" maxlength="5"

                                                                      readonly="#{myFormAction.formMode == 'VIEW'}">

                                                                      <f:convertNumber maxFractionDigits="2" groupingUsed="false" pattern="#.##"/>

                                                                      <a4j:support event="onblur" reRender="gradePoint" />

                                                            </h:inputText>

but still not working

Please help me guys. I really need your hand

1) Could you try to use <f:validateDoubleRange minimum="0" maximum="99.99"/>?

2) What type does gradePoint field have?

P.S.

If it won't match to your requirements I suppose you should write your own convertor/validator.

1. Could you try to use <f:validateDoubleRange minimum="0" maximum="99.99"/>?

yes I can, but once I change into correct value, arise error like this

java.lang.IllegalArgumentException: argument type mismatch

I put <rich:message for="gradePoint" /> under the panel

2. gradePoint is Double.

Please help, I'm newbie in richfaces. Many thanks.

You should have <rich:message for="gradePoint"/> on your page. It will be updated automatically with every ajax request. If you want to use h:message you should reRender h:message element by yourself. (In a case of full page submit both work in the same way)

Hi Ilya,

I already updated my response. So I already put <rich:message for="gradePoint" /> under the panel.

but once I change into correct value, arise error like this

java.lang.IllegalArgumentException: argument type mismatch

Please, could you provide a stack trace of the exception and your latest java and xhtml code.

Hi Ilya,

Solved already. I just create my own validator to check the length. Thanks.
