Setting the value in <s:textfield from request scope

[Jigar Naik]

Hi,

I want to set the value in textfield, the value is in requet scope.

how do i do it ?
i tried to use <s:property tag but i am not able to nest it in ><s:textfield tag.

my action class which sets the value in request is as bellow

public String redirectEditModule() throws Exception {
		request.setAttribute("module", moduleDAO.getModule(module.getId()));
		request.setAttribute("mode", "edit");
		return SUCCESS;

and my jsp

on which i want to set the value is as bellow

...
...
><s:if test="#request.mode == 'edit'">
		<h3>Edit Mode</h3>
		<s:textfield name="code" id="code" required="true" value="%{request.module.code }" label="Module Code" maxlength="20"></s:textfield>
		<s:textfield name="name" id="name" required="true" value="" label="Module Name" maxlength="40"></s:textfield>
		<d:datetimepicker name="expiryDate" id="expiryDate" value=""  label="Expory Date" displayFormat="yyyy-MM-dd"></d:datetimepicker>
		<s:submit name="Save" align="center" ></s:submit>
		</s:if>
...

Hi,

You just remove request. from your text field tag.

   <s:textfield name="code" id="code" required="true" value="%{module.code}" label="Module Code" maxlength="20"></s:textfield>    

And you will get the value.

That's incorrect; OGNL expressions do not search JEE scopes. If a JSTL expression is used the request wrapper *will* search the value stack first *then* fall back to a scoped attr. The OGNL expression *would* require the request, but with a hash mark: #request.

The larger question is why do it this way at all? S2 provides an elegant mechanism making setting and using values like this in the request scope unnecessarily cumbersome--just make the values action properties:

private String mode;
private Module module; // Or whatever type it really is.
public String getMode() { return mode; }
public Module getModule() { return module; }
public String redirectEditModule() throws Exception {  
    module = moduleDAO.getModule(module.getId());
    mode = "edit";
    return SUCCESS;  
}

Then in the JSP:

<s:if test="mode == 'edit'">  
  <h3>Edit Mode</h3>  
  <s:textfield name="code" id="code" required="true" value="%{module.code}" label="Module Code" maxlength="20"/>
  ... etc ...

Thanks David & Nishan.

Bellow worked... I found it by googling.

%{#request['module'].code}

but i am not sure how it works... Can you please explain ? What do i get with "%" & "#"

[David Newton]

%{} is the OGNL escape. The # means it's an action context "scope" variable, not on the stack.

Again--there's zero reason to do it like this, and at least a couple reasons not to.
