Passing parameters to 

Hello.

I need to access a property the includes a parameter but I cannot find a way
to do it.

I want to list all page names in selectedPages but I also need to specify
the locale (language) the should appear because a page may have many names
in different languages:

This works fine. It's a normal getName():

<ul>
    <s:iterator value="selectedPages" status="row">
        <li>
            <s:property value="name" />
        </li>
    </s:iterator>
</ul>

but I needed to do something like

<ul>
    <s:iterator value="selectedPages" status="row">
        <li>
            <s:property value="name(Locale.US)" />
        </li>
    </s:iterator>
</ul>

Best Regards,
Ricardo

use an alias in the getName call like so

 

<s:property value="getName('US')"/>

 

this will still call getName but pass the string "US" then make the class method getName do the locale related work.

 

you can't pass an object in a property call as far as i know only a primitive/string.

 

i still think you should be looking at this differently and using the i18n interceptor and resource bundles to handle different languages.

Re: Passing parameters to

Posted by Ricardo Jorge <rv...@gmail.com>.
Thank you both for your help. I got this working with your suggestions. :)

I made an experiment with various ways of working this out. Here are the
results. They may be helpful to others looking for the same answer.

1. Doesn't work
            name('Locale.US'): <s:property value="name('Locale.US')" />


2. Doesn't work
            name(Locale.US): <s:property value="name(Locale.US)" />


3. Doesn't work
            getName(Locale.US): <s:property value="getName(Locale.US)" />


4. Works. notice the ' in the parameter
            getName('Locale.US'): <s:property value="getName('Locale.US')"
/>

5. Works. i tried something similar before but I was just using 'name'
instead of 'getName'
            getName(@java.util.Locale@US): <s:property
value="getName(@java.util.Locale@US)" />


6. Doesn't wok. I tried this previously. See nº5
            name(@java.util.Locale@US): <s:property
value="name(@java.util.Locale@US)" />


7. Works but probably only because there is also a getName(String s) where s
is the locale as a string
            name('en_US'): <s:property value="getName('en_US')" />


8. Works but probably only because there is also a getName(String s) where s
is the locale as a string
            name('US'): <s:property value="getName('US')" />



Also, I did not need to use struts.ognl.allowStaticMethodAccess

@adam: I'm using Liferay and this is a class provided by the Portal to get
the names of the pages in localized format. The getName method (without
parameters) returns XML content with the various languages so I need to get
the right locale using the provided getName(Locale locale).

Perhaps I could create an additional class where I would store the
information I need in an already localized format and handle this in the
Action.

Ricardo

RE: Passing parameters to

just pass an alias to the locale in the parameter

 

<s:property value="getName('US')"/>

 

and let the getName class handle the actual locale.

Take a look on some examples here [1] and try
<s:property value="getName(@java.util.Locale@US)" />

Thank you for your reply.

I don't have a getName in my action class if that's what you mean.

I'm using an iterator so the getName is a method from the class's object
defined in the iterator's value option. That class also makes available a
getName(Locale locale).

Locale is a class (java.util.Locale).

PS: I've just tried the following but it did not work
<s:property value="name(@java.util.Locale@US)" />

Best Regards
Ricardo

Did you define method name(Locale locale) in your class? Or just
getName(Locale locale)? For second case use
<s:property value="getName(Locale.US)" /> or <s:property
value="%{getName(Locale.US)}" />
