Tags and variable attributes
Hi all,
I have an action property holding a key in a properties file. In the view
page, I like to display the value of the key. Since struts tags only accept
plain text as attribute values, I can only render the key in the view like
this:
<s:property value="varHoldingKey"/>
Using <s:property value='getText("varHoldingKey")"/> is NOT allowed because
of syntax error.
Is there a way to display the key's value?
Thanks.

Before you were using ognl to call getText with a string argument
"varHoldingKey". Without those strings you're now calling that same
method with the evaluated value of the action attribute varHoldingKey.
(Technically, varHoldingKey is evaluated against the value stack, but
typically the action is the top item on that stack, so as long as your
action has that attribute, and nothing higher on the stack does as well,
the result is the same.)

It works. What's behind it? I even can't believe it.
Thanks so much.

So, have you tried <s:property value='%{getText(varHoldingKey)}'/> ?

Thanks Dave.
I wanted to do it either in the bean class or in the view page but now it
seems I have to deal with that in the action class.
Thanks again.

Get the text in the action.
You should be able to call a method inside getText, though.

Thanks Dave and Dale.
If the "varHoldingKey" is a key, it works fine. However, it is not a key
itself. It is an action property holding the key.
Suppose the key is "confirm.title" so varHoldingKey's value is the "
confirm.title" string. In the view, <s:property value="varHoldingKey"/> will
display "confirm.title".
<s:property value='getText("varHoldingKey")'/> doesn't show the value of the
key "confirm.title" as it tries to display the value of the key
"varHoldingKey" but actually the "varHoldingKey" is not a property's key and
it is a variable holding the key.
My question is if there is a way to display the key's value in the view page
with the variable holding the key but actually not knowing what the key is.
Many thanks.

The syntax error is that you have unmatched ''s and "'s.

Is that a typo?
I use getText(...) inside <s:property.../> tags fairly frequently w/o issue.
