 Don't know if this solves your problem, but maybe it helps to use the
 params-prepare-params trick, calling params interceptor twice, so you have
 your params ready before prepare().

 You have an already configured stack, the paramsPrepareParamsStack

 From struts-default.xml:

 !-- An example of the paramsPrepareParams trick. This stack
 is exactly the same as the defaultStack, except that it
 includes one extra interceptor before the prepare
 interceptor:
 the params interceptor.

 This is useful for when you wish to apply parameters
 directly
 to an object that you wish to load externally (such as a
 DAO
 or database or service layer), but can't load that object
 until at least the ID parameter has been loaded. By loading
 the parameters twice, you can retrieve the object in the
 prepare() method, allowing the second params interceptor to
 apply the values on the object. --

  Hi,

 I have read the documentation How do we repopulate controls when
 validation
 fails [1]. I tried the action tag solution. However, when there is a
 validation error, the execute method of the action ins:action  is not
 called.

 I don't choose the Preparable solution because the parameter required is
 not
 ready in the Prepare stage. (For the first time of visit, the parameter is
 set to default.) And I don't want to call the preparation twice in both
 execute and prepare. So what is the best way to repopulate controls for
 normal case and revisit after validation error? Should I abandon to
 validate
 the input in validate method?

 Thanks.

Get i18n text problem

[Franz Wong]

Hi group,

In the jsp page, I have a page scope variable title. This variable stores
the key of the resource bundle. I can print the value by %= title %.
However, I am not able to use it with s:text/.

I have tried s:text name=${title}/ or s:text name=%= title %/. But
both of them do not work.

Thanks.

Clear ThreadLocal of ActionContext

[Franz Wong]

Hi,

I would like to ask is there any mechanism clearing ThreadLocal of
ActionContext by struts? As I know, there are some issues when ThreadLocal
is used with thread pool.

Parse url parameter

[Franz Wong]

Hi group,

Suppose I have an URL with parameters (e.g.
http://localhost:8080/myApp/action/myAction/user/name/Peter).

I would like to map those parameters in the following way.

class MyAction {
private String searchType; // user
private String searchMethod; // name
private String searchData // Peter
}

Is there any Action class can parse the parameters into properties of
Action?

Thanks
Franz

Strange behaviour on i18n

[Franz Wong]

Hi,

I have an i18n web site with struts 2. I don't know why the i18n text is not
loaded properly. I expect 檢索詞不能空白 (Chinese characters), but it turns out
檢索詞不不能空白. But if I make any change on the html (e.g. the order of
attributes or remove some elements), the text is loaded without any problem.

Thanks.
Franz

Problem html code :

input type=button value=s:text name=search/
onClick=searchButtonClick('s:text name=search.searchTermCannotBeEmpty
/');/

(HTML : input
type=button value=檢索 onClick=searchButtonClick('檢索詞不不能空白');/)

However, the following html code works fine.

input type=button onClick=searchButtonClick('s:text
name=search.searchTermCannotBeEmpty /'); value=s:text
name=search//

(HTML : input type=button onClick=searchButtonClick('檢索詞不能空白');
value=檢索/)

Properties file :

search.searchMethod=檢索方法
search.searchMethod.Title=書名
search.searchMethod.Author=著者
search.searchMethod.Subject=主題
search.searchMethod.Series=叢書
search.searchMethod.TitleKeyword=書名關鍵詞
search.searchMethod.AuthorKeyword=著者關鍵詞
search.searchMethod.SubjectKeyword=主題關鍵詞
search.searchTerm=檢索詞
search.searchTermCannotBeEmpty=檢索詞不能空白
search=檢索

Here is the whole jsp file.

Display ActionMessage added from different action

[Franz Wong]

Hi,

I am using Struts 2. I have a page which contains 2 forms. Each form
corresponds to different Actions (Action B / C). The action adds
ActionMessage and redirects back to the original page. I would like to
display the ActionMessage in the form which triggered the Action. How do I
perform this in Struts? As I see, addActionMessage method only accepts
single string as parameter.

Action A = Main JSP (Containing 2 Forms) = Action B / C (Both action adds
ActionMessage) = Action A

Thanks.
Franz
