S2 Using with parameters

Hi

 

I’m using the Struts 2 validation framework and using message properties
like this:

 

message.requiredfield = The field "${getText(fieldName)}" is required

 

Now I need to do some extra javascript validations where I need to get the
message from the property files but I can’t get:

 

<s:text name="message.requiredfield"><s:param name="fieldName"
value="projectDocument"/></s:text>

 

to work. I don’t know if this is possible. Do I have to create another
message key for this?

 

Regards,

 

Néstor Boscán

Yes I also think that only positional parameters would work, which means I
have to create another message just for this case. Struts 2 should allow
developers to use messages with positional parameters with the validation
framework so you can have just one type of message.

I don't think that's how it would work; if I had to guess I'd say that 
only positional message parameters would be possible--could be wrong 
about that.

That said, you can still call the getText() variant that takes a list or 
an array--this should be doable using OGNL syntax; something like:

<s:property value="getText('message.requiredField',
                            { 'projectDocument' })"/>

IIRC you can also construct actual arrays:

<s:property value="getText('message.requiredField',
                            new String[] { 'projectDocument' })"/>

if the first way doesn't work.
