I try myfaces-examples (last cvs) – myfaces is JSF implementation with added components like datalist,tree etc and validator like regexp validator

in examples application is there validate.jsp with this :

<h:inputText id=”regExprValue” value=”#{validateForm.regExpr}”
required=”true”>
<x:validateRegExpr pattern=”\d{5}” />
</h:inputText>

Myeclipse return erro on line 3 (\d{5}) :

Invalid escape sequence (valid ones are \b \t \n \f \r \” \’ \\ )

This is correct syntax

I disagree, since the backslash is the escape character, it must be escaped:

 <x:validateRegExpr pattern="\\d{5}" /> 

regards

NOP

I try and have same error in myeclipse

snpe,
Try and add slashes until the error goes away… I ran down something like this with another person in another thread and they ended up needing: “\\\\d” or something to that effect… if you read the regular expression docs in Java, you someitmes run into this situation as well where you need to super-escape sequences… its a bit of a mystery to me.
