Hi, Thanks so much Martin.........but I am not trying to validate a date field, I am actually trying to give a dynamic initial value to a text box through struts-config.xml.
<form-property name="date" type="java.lang.String" initial="rd.admin.DateFormat.getDate()"/> Regards, Shivani -----Original Message----- From: Martin Gainty [mailto:[EMAIL PROTECTED] Sent: 03 December, 2005 8:20 PM To: Struts Users Mailing List Subject: Re: Preserving the query string while validating a form & using dynamic initialization with DynaAction Good Morning Shivani/Raghu Assuming the date for the QueryString is a valid date following the tutorial for date-validation with struts validator at http://www.roseindia.net/strutstutorial/usingstrutsvalidatorframewor.sht ml in your "form" capture the date information in a html:text tag e.g. DATE: <html:text property="date"/> we have a string which needs to be transformed and validated to well-formed date we can use field level datePattern validation of "MM/dd/yyyy" to validate the form value before attempting a populate e.g. <field property="date" depends="required,date"> <arg0 key="form.date" /> <var> <var-name>datePattern</var-name> <var-value>MM/dd/yyyy</var-value> </var> </field> Anyone else?

The option (a) for Query 1 actually works............ Thanks a ton! In set up action, I was trying to get the values through "request.getParameter("id0")", changing it to "form.get("id0")" worked. About the 2nd query, when I write, <form-property name="date" type="java.lang.String" initial="rd.admin.DateFormat.getDate()"/> ..the text box displays "rd.admin.DateFormat.getDate()" literally. Is there any way that I could get the form value to be evaluated rather than just outputting it as is?

You will need to "burn" this querystring information into (a) the form object or (b) the session. (a) If you are using dynaction form, then just adding another variable to hold the id0 in the config.xml definition should be less painful. But even if you are using the regular "typed" action form, then also it should not be too much of a trouble to add the extra parameter. You can then map this parameter to a hidden variable in your jsp. (b) Instead of reading the variable form querystring/request object, burn it in to the session and read it from there. You could have a helper function ( a getId0( ) ) which checks if the variable is in the query string then it returns from the request object, else it should look up the session. Prevalidation, it would find it in the the request object, post validation it can pick it up from the session. Be aware that the drawback of this approach is that the user may have contamination of this variable if she opens another window from the same browser (like a Ctrl N in internet explorer) which will share the same cookie and hence the same session. But this is true in all cases where you use session scoped variables. >Query 2: I doubt if you could do that! The xml config files are fairly static in my opinion. But I am just guessing.
