Re: getText returns NULL when formating number using l10n
If you want a definitive solution, i suggest you create a new method like: getTextEx(.) in your action, in this method, you can check the parameters, if they are null, change them to empty string, and then invoke the original getText method. you can put this method in the base class of your actions, so you can use it in all the actions. 2011/11/23 Felipe Issa : > It's not a definitive solution, but it works.

Re: getText returns NULL when formating number using l10n
or you can do the null check in the jsp code, before you create the param list for the format string. Code like: 2011/11/22 Felipe Issa : > Hi.

Re: getText returns NULL when formating number using l10n
I have read the source of java.text.MessageFormat, looks like it output a "null" text to the result String when the argument is null. I think you can create a read-only property in your action (or your data model class), and implement the null check and format process in this property, code like: public String getPriceDisplay(String formatPattern) { if (this.price == null) { return "" } else { format it by the formatPattern } } and use this property in the jsp tag, code like: 2011/11/22 Felipe Issa : > Hi.

getText returns NULL when formating number using l10n
Hi. I'm trying to internationalize my application, and for that i need to use the struts l10n. I have managed to parse the number according to the user locale, but I'm having some troubles to display the number using the user locale. On Struts 2 documentation it says: "to input a number, one might have noticed that the number is always shown in the Java default number format. Not only that this is not "nice", if you are in a non-en locale, it will also cause trouble when submitting the form since type conversion is locale aware. The solution is to again use the message formats as defined above, by using the getText Method of ActionSupport: value="%{getText('format.number',{orderItem.price})}" /> This maps to the method signature getText( String key, Object[] params ) in ActionSupport." (http://struts.apache.org/2.x/docs/formatting-dates-and-numbers.html) It display the number in the correct format when i use the value like this, but when the value is null it shows "null" instead of a empty textfield.
