[S2] How to add a custom parameter to an existing Struts UI Tag?
I am trying to override a struts tag template (specifically
s:checkboxlist), and I can't figure out how to add a parameter to
the tag. I have successfully overridden the template by copying
checkboxlist.tld to my template/simple directory and all works well.
Now I would like to add a parameter. It appears that I need to
override the the META-INF/struts-tags.tld file because I keep getting
the error below. However, using the same method as checkboxlist.tld,
I copy a modified version of struts-tags.tld to my
META-INF/struts-tags.tld directory. However, I still get the same
error below. Not sure if I need to modify another file or if
struts-tags.tld cannot be overridden. Anyone given this a try?
Trying not to have to create a new custom tag since all I want is a
simple modification to checkboxlist.tld.

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
Do you need to insert a breaking string every 3 items?
I think this approach is too much expansive in term of time.
Furthermore, after that, you should deal with subcassing process.
You should have valid reasons for do that.
Why don't you simply use mod operator?:
s:iterator status=stat value={1,2,3,4,5}
s:if test=(#stat.index % 3)==0
insert breaking string
/s:if
.
/s:iterator

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
I think encapsulating this kind of behavior in a custom tag is why
custom tags exist--and since the iteration is handled by the
checkboxlist tag internally, using an iterator/etc. doesn't really
work.

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
Much cleaner to encapsulate the behavior, especially if it's used
often. It might be easier to use a JSP-based tag, though, than to
extend an S2 tag.

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
Agreed. I think an upgrade to the checklistbox tag is in warranted.
Through my searches there are many posts looking for ways to layout
the checkboxlist better. Most frustrating on this tag is the actual
checkbox and the label will break lines making this unacceptable from
a UI perspective. Also, many users I saw just wanted a one column
format. I would propose surrounding the input type=checkbox and
label html elements in a div tag (you could even supply an
additional class and style attribute to the tag). This way a user
could set widths, floats, etc for the div tag. This hack below did
the trick for me. By setting the div Class properties: float in
combination with width you can easily set up one column lists or
fixed width layouts that extend to the next line easily. Would make
this tag much more versatile - especially with just a small
modification.
#-- Modified checklistbox.tld with surrounding div tag --
div class=myCustomDivClass
input type=checkbox name=${parameters.name?html}
value=${itemKeyStr?html}
id=${parameters.name?html}-${itemCount}#rt/
#if tag.contains(parameters.nameValue, itemKey)
checked=checked#rt/
/#if
#if parameters.disabled?default(false)
disabled=disabled#rt/
/#if
#if parameters.title??
title=${parameters.title?html}#rt/
/#if
#include /${parameters.templateDir}/simple/scripting-events.ftl /
#include /${parameters.templateDir}/simple/common-attributes.ftl /
/
label for=${parameters.name?html}-${itemCount}
class=checkboxLabel${itemValue?html}/label
#-- Add ending div tag --
/div

I ended up not having to create a new tag. I simply overrode the current template (template/simple/checkboxlist.tld) to do what I wanted.

Hi Burton, I see, that would be the problem cause that ERROR. You have to download the struts2 source, and take a look at the both org.apache.struts2.views.jsp.ui.CheckboxListTag and org.apache.struts2.components,CheckboxList. I think you must add the attribute breakCount into CheckboxList.java, then it will work, maybe. I am not sure about that, I am also got the same problem, when creating myself Tag. Good Luck.

Thanks for the email. I was afraid it might be a bit more involved. I will probably shy away from that sort of surgery. Once you start modifying the Struts source, it can make future Struts upgrades painful.

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
Hi Burton: The error message looks like the TLD file does not defined the new attribute correctly. So i think maybe the execute environment is not using the modified TLD file but the old one. Can you show us how you do apply your TLD file to the execute environment? - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
