Re: Struts2 Checkboxlist
I am using the defaultStack but the ArrayList used for the checkboxes is of type Long. If we change it to ArrayList of Boolean would the interceptor set the values to false? Or is this only applicable if you have individual checkboxes rather than checkboxlist?

RE: Struts2 Checkboxlist
Yes, setFoo is only called if the checkbox is checked. However, Struts 2 does have a checkbox interceptor: https://struts.apache.org/core-developers/checkbox-interceptor.html This interceptor defaults checkbox Boolean's to False if the box is not checked. This is part of the default interceptor stack.

Re: Struts2 Checkboxlist
Is that how Struts2 is expected to work? Meaning setFoo would not be called if non of the Foo checkboxes are selected? I know that is how Struts1 worked.

Re: [struts-user] XML based configuration
Hi Lukasz, Here's a summary of how Roller uses Struts and Tiles: Roller uses the StrutsPrepareAndExecute filter and maps it to all requests ending with “.rol” https://github.com/apache/roller/blob/master/app/src/main/webapp/WEB-INF/web.xml Roller’s actions are defined in struts.xml and return results of type “tiles” https://github.com/apache/roller/blob/master/app/src/main/resources/struts.xml Roller’s JSP pages are kept under /WEB-INF/jsps to prevent direct access to them. You can see that in the tiles.xml file https://github.com/apache/roller/blob/master/app/src/main/webapp/WEB-INF/tiles.xml Hope that is helpful. What else can I tell you about Roller and it's use of Struts & Tiles?

Re: Escaping dollar sign and curly brackets
Hey Lukasz, thanks for your reply.
Actually, I don't want to use struts tag replacement mechanism, but one
of my own.
I already solved my problem as you probably read by now.
Cheers and thanks for your help.

Re: Escaping dollar sign and curly brackets
Hey Yasser,
Thanks for your reply. I tought I tried every combination you suggested,
but it seems that I missed the *$'{placeholder}'* variant.
This works for me. Thanks for your help!

Subject: Escaping dollar sign and curly brackets
Hey,
In my action I'm using getText(myKey) to get a localized string. This string has
some placeholders of mine, in ${placeholder} format. Consider my original key is
defined as this in my properties file:
myKey = Some text ${placeholder} more text.
I've read in Struts documentation that it uses MessageFormat. So, if I want
literals, I need to use single quotes. This is what I did in my properties file:
myKey = Some text '${placeholder}' more text.
However, when I call getText(myKey) I get: Some text ' more text. Why does this
happen?
It seems firstly ${placeholder} is evaluated to empty by Struts then '' is
evaluated to ' by MessageFormat.
I also noticed that the problem is the dollar sign AND curly brackets without
any
character in between. If I have this definition:
myKey = Some text '$' text '{placeholder}' more text.
It gets resolved to: Some text $ text {placeholder} more text.
Can somebody explain me how can I escape the dollar and curly brackets
characters?
I guess '$'{placeholder} or $'{placeholder}' or '$''{placeholder}' should work
:\ could you please report back the result for each one? And which Struts
version you test?
Thanks for using Struts!
Kind Regards.
