Re: problems nesting TileResults....
Hi Antonio, I got a 2.0.6 snapshot and the issue is fixed! Thanks much for the tip. Also noteworthy is that now that I have actions that can forward to tiles which have nested within them actions that also forward to tiles (whew), in order for action context to be available to JSP pages I had to follow the steps to include the struts-cleanup filter in web.xml. The docs on the struts2 site say that this filter is solely for the purpose of sitemesh integration, but apparently it's beneficial to tiles integration as well thanks again, - Darren.

problems nesting TileResults....
Hello All,
I have a flow that is basically a toplevel struts2 action having a
result of type TilesResult. That tile
result has as one if it's attributes another struts2 action that also
has a result of type TilesResult.
So my tiles.xml looks like this (I've changed names and attributes to
try to simplify the example
as much as possible)
definition name=pageLevelTile extends=somePageLevelTemplate
put-attribute name=header
value=/WEB-INF/tiles/pages/header.jsp /
put-attribute name=body value=/findTileBody.action /
/definition
definition name=moduleLevelTile extends=someModuleTemplate
stuff
/definition
---
So i have an action, call it showPage.action that forwards to
pageLevelTile, then
within pageLevelTile the body attribute invokes the action
findTileBody.action
that eventually forwards to the moduleLevelTile.
The issue with this is the browser only renders the moduleLevelTile (all
the
surrounding page-level stuff gets wiped out for some reason), and I'm
seeing this
exception:
-

Re: About OGNL multi-threading contention
actually struts is currently using ongl 2.6.11 correct? In fact the problem that you reference here http://jira.opensymphony.com/browse/OGNL-141, seems to indicate it was the 2.6.11 version of the OGNL jar that introduced the problem. Can someone verify? I would second the idea that this is a very important issue for my project. Not sure if this is the appropriate forum to raise this issue, but I desperately need a patch. Does anyone know if downgrading to OGNL-2.6.10 would solve the problem? Looking at the sources the synchronization on the method object in the OgnlRuntime.invokeMethod seems to be the only difference between the two versions... thanks, - darren Telmo Costa wrote: Hello, We’ve been testing an application in a production environment and found a serious contention problem when the number of simultaneous requests grows. The problem seems to be related with the use of static synchronized blocks in OGNL code. I’ve found a related issue in OGNL (http://jira.opensymphony.com/browse/OGNL-141) that is already fixed in version 2.7.2. But, another related issue (http://jira.opensymphony.com/browse/OGNL-10) is still open, although it already has a patch. Does anyone know when Struts2 team is upgrading the OGNL version?

Re: freemaker model population
Sorry for the confusing question. I tried this again and it seemed to
work fine
(i.e. accessing objects that are not on the top of the value stack via
ognl expressions
via the ${foo} syntax in freemarker templates)
However, I did find a couple of places where I had to use the struts
property tag
instead. For example
s:set name=foo value=bar.baz/
I could not use ${#foo}, I had to use s:property value=#foo/.
Are there any other gotchas with ${} vs. s:property value=/
thanks peeps,
- darren.

Re: tag writers resources?
Hi Joachim,
This gives me something to start with. Time to dig into the struts2
source code to help me grok the sample you've provided.
thanks,
- Darren.
Joachim Ansorg wrote:
Hi Darren,
writing a simple Struts2 tag is not that difficult. But getting
started is.
The documentation of the tag api is not very good, imho. The best start
is in my opinion to get the Struts2 sources and read the source code of
the existing struts2 tags.
I'm posting a simple example with this mail so it's in the archives for
anybody. A tag writers guide would be a very useful resource for S2 users.
For a S2 body you basically need:
-A JSP tag implementation. e.g.:
public class NameValueTag extends AbstractUITag{
private String editMode;
public Component getBean(ValueStack valueStack, HttpServletRequest
httpServletRequest, HttpServletResponse httpServletResponse) {
return new NameValue(valueStack, httpServletRequest,
httpServletResponse);
}
protected void populateParams() {
super.populateParams();
((NameValue) component).setEditMode(editMode);
}
public String isEditMode() {
return editMode;
}
public void setEditMode(String editMode) {
this.editMode = editMode;
}
}
-A Struts2 component which is used by Struts. The JSP tags sets the
attributed on the component. The annotations are later used for
automatic .tld generation. I'm using Maven for that.
@StrutsTag(name = nameValue, description = Inserts a formatted
name-value html code construct., tldTagClass =
gr.ksi.tags.ksiplugin.views.jsp.NameValueTag)
public class NameValue extends ClosingUIBean {
private String editMode;
public NameValue(ValueStack valueStack, HttpServletRequest
httpServletRequest, HttpServletResponse httpServletResponse) {
super(valueStack, httpServletRequest, httpServletResponse);
}
public String getDefaultOpenTemplate() {
return ksinamevalue;
}
protected String getDefaultTemplate() {
return ksinamevalue-end;
}
@StrutsTagAttribute(description = Set to true to display edit boxes
instead of text labels., required = false, type = Boolean)
public void setEditMode(String editMode) {
this.editMode = editMode;
}
public String isEditMode() {
return editMode;
}
protected void evaluateExtraParams() {
if (editMode != null) {
addParameter(editMode, findValue(editMode, Boolean.class));
}
}
}
And you need Freemarker templates which render the html. Have a look at
the getDefaultTemplate() and getDefaultOpenTemplate() methods above.
These point to the corresponding freemarker templates.
The open template in this example is:
[#ftl]
[#if parameters.editMode?exists parameters.editMode == true]
div class=name_value_edit
span class=name
[#if parameters.label?exists] [EMAIL PROTECTED]
value=parameters.label /] [/#if]
/span
span class=value
[#else]
div class=name_value
span class=name
[#if parameters.label?exists] [EMAIL PROTECTED]
value=parameters.label /] [/#if]
/span
span class=value
[/#if]
The closing template is just:
[#ftl]
/ul
The rendered body is put in between.
These examples are a full implementation of a S2 tag.
If you want to place custom actions before and after the body rendering
I think overriding ClosingUIBean.start and ClosingUIBean.end (don't
remember the right name atm).
Hope that helps,
Joachim
Hi All,
Does anyone (know of/have any) resources that cover writing a tag?
I want to write a struts2 body tag that sets some applications specific
state before it emits it's body, and clears the state once the body has
been emitted. Any tag-writers guides out there???

Re: [struts] tag writers resources?
Hi Dale, Yes, i'm familiar with writing JSP tags, although it's been quite some time since i've done so. It took me about 1/2 an hour to dust off the cobwebs and write a JSP tag extending BodyTagSupport that did what I wanted it to do. What I was more interested in is some guidelines similar to what Joachim posted in writing a struts2 tag. And by that I mean one of those generic, technology independent beasts that can be used in Freemarker and Velocity as well as JSP. thanks, - Darren.

Re: including the output of an action execution in a servlet response.
I finally found the answer for any that are interested. servlet filters apparently don't trigger (by default) on forwarded and included requests. I had to change my filter url mapping in web.xml to make the struts2 filter fire from: filter-mapping filter-namestruts2/filter-name url-pattern/*/url-pattern /filter-mapping to: filter-mapping filter-namestruts2/filter-name url-pattern/*/url-pattern dispatcherREQUEST/dispatcher dispatcherFORWARD/dispatcher dispatcherINCLUDE/dispatcher /filter-mapping cheers, - darren.

question about interceptors
Hi all, I'm new to struts2 and have some questions about configuring Interceptors. If your action does not define an interceptor does it get the default one (i.e. defaultStack)? e.g. action name=MyAction class= // does this action get the struts2 default interceptor stack result/myAction.jsjp/result /action also, if your action *does* define an interceptor, does that augment the default one or override it? e.g. action name=MyAction class=... interceptor-ref name=myinterceptor/ // do i get defaultStack, or did i just override it? result/myAction.jsp/result /action thanks, - darren. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
