I'm learning Spring and webflow and I'm having trouble with something which seems like it should be simple. My flow is capturing a query string parameter and stashing it in a flow-scoped variable when the flow begins. I'm trying to echo it on the first view-state. Errors ensue.
Here's the flow definition:
<?xml version="1.0" encoding="UTF-8"?>
<flow xmlns="http://www.springframework.org/schema/webflow"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/webflow
http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">
<on-start>
<set name="flowScope.foo" value="requestParameters.fubar" />
</on-start>
<view-state id="step1" view="../jsp/step1.jsp">
<transition on="next" to="step2" />
</view-state>
<view-state id="step2" view="../jsp/step2.jsp">
<transition on="next" to="step3" />
<transition on="prev" to="step1" />
</view-state>
<view-state id="step3" view="../jsp/step3.jsp">
<transition on="prev" to="step2" />
<transition on="next" to="done" />
</view-state>
<end-state id="done" view="endView" />
<end-state id="cancelled" view="../jsp/cancelledView.jsp" />
<global-transitions>
<transition on="cancel" to="cancelled" />
</global-transitions>
</flow>
step1.jsp:

Resulting error:

...
If I omit the attempt to access the key "foo" the page renders with the following output (where the query string is ?fubar=baz):
This is step 1
flowRequestContext.flowScope: map['foo' -> 'baz', 'viewScope' -> map[[empty]]]
FLOW SCOPE IS EMPTY!
flowRequestContext.FLOW SCOPE IS *NOT* EMPTY!
It looks like the identifier flowRequestContext.flowScope does refer to a map, and it looks like it does contain the key and value I would expect... but if I try to access it like a map in EL it doesn't cooperate.
just use ${foo} everything in your flowscope should be accessible with $

I have a problem when adding view parameters to a <h:link includeViewParams="true" /> - they are not added to the rendered link. I am using Mojarra 2.3.9.

Been working on wrapping my head around expression engine now. And I'm using the Structure add-on as well. This is my first attempt of building my own template.
The problem I'm having is on the index page when you initially land on the site. It will repeat the entire html over and over until its' loaded every pages' content. It only does this on the index page. If you click on any other page it works as its supposed to.
Heres my code:
<!DOCTYPE html>
<html>
{exp:channel:entries channel="pages"}
<head>
<meta charset="UTF-8">
{!-- add="filename|filename2" --}
{embed="Pages/styles"}
{embed="Pages/scripts"}
<title>{title}</title>
</head>
<body>
<header>
<img src="img/logo.png" />
<nav>
{exp:structure:nav css_id="none" start_from="/" show_depth="2"}{/exp:structure:nav}
</nav>
</header>
<main>
<nav>
{exp:structure:breadcrumb inc_home="no" here_as_title="yes"}{/exp:structure:breadcrumb}
</nav>
{if structure:child_ids != '' OR structure:parent:entry_id != '0'}
<aside>
{exp:structure:nav css_id="none" show_depth="2" start_from="/{segment_1}" show_overview="yes" rename_overview="{structure:top:title}"}{/exp:structure:nav}
</aside>
{/if}
<article>
<h1>{title}</h1>
{page_contents}
</article>
</main>
<footer>
<nav>
{exp:structure:nav css_id="none" start_from="/" max_depth="1"}{/exp:structure:nav}
</nav>
<address>
<p>1234 Address St<br />
City Name, STATE 12345<br />
Phonee: 123 456 7890<br />
Email Us</p>
</address>
</footer>
</body>
{/exp:channel:entries}
</html>
And here is the link to the site: (no styling, just building and testing for now) http://www.oneoffs.co
It's not the prettiest solution but you could simply add entry_id to the loop which would limit it to only the homepage.
{exp:channel:entries channel="pages" entry_id="1"}
..
{/exp:channel:entries}
or
{exp:channel:entries channel="pages" {if segment_1 == ''}entry_id="1"{/if}}
..
{/exp:channel:entries}
...which only adds the entry_id if you're on your homepage (assumption that segment_1 is blank).
Using VB.NET in Visual Studio 2010, I have two files:
"test2.aspx" and "test2.aspx.vb".
The aspx file is basically as follows:
<%# Page Language="VB" AutoEventWireup="false" CodeFile="test2.aspx.vb" Inherits="App_test2" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta id="meta1" runat="server" name="description" />
</head>
<body>
<textarea id="text1" runat="server" />
</body>
</html>
The vb file is basically like this:
meta1.Attributes("charset") = "UTF-8"
meta1.Attributes("content") = "I'm a description tag"
text1.InnerText = "&'<>"
This all displays as expected in the browser, but the source code when the page is rendered looks like this:
<html>
<head>
<meta id="meta1" name="description" content="I'm a description tag" charset="UTF-8"></meta>
</head>
<body>
<textarea name="text1" id="text2">&'<></textarea>
</body>
</html>
Is there something I can do so the source code doesn't escape characters like "&", "'", "<", and ">" ?
You don't. If it didn't convert those characters, the browser would incorrectly interpret them as commands instead of data. It shouldn't be an issue for you because it is always converted back to the character data in code. text2.Text would contain the values you want, not the escaped data.
I'm currently creating a web application using the jquery+struts plugin. It also uses hibernate. I have two web pages already, the other one works perfectly fine but when I created another one, it threw an error saying that the action cannot be found. The error is:

The other page already worked. With just some refresh and restarts on the server, the page just worked fine. :) Weird though.. :)
I have a problem with using a script that adds a NiceEdit toolbar to a text area when that text area is within an Ajax tab.
I want to know if I should refer to it in a different way than just the ID.
I mean the ID of that text area, I tried to take the text area outside the Tab Container, it works, but when I return it, it simply doesn't.

});

txt is the server ID of your control, you have to use the client ID :
....panelInstance('<%= txt.ClientID %>');
Basically, the client ID is derived from the server ID and the naming container where your control is, to avoid any naming conflict. When your text area is not in the Ajax Tab, the client ID is the same as the server ID. When you put the text area in the Ajax Tab, it's client ID is different (you can check that by looking at the page source in your browser).
EDIT:
From Maen
I viewed the page in browser, checked
the ID in the page source, it was
"TabContainer1$first$txt", used it
instead of "txt" and the script was
like: panelInstance('<%=
txt.TabContainer1$first$txt %> I got
an error: BC30456: 'TabContainer1' is
not a member of
'System.Web.UI.WebControls.TextBox'.
That's not what I meant : you have to put panelInstance('<%= txt.ClientID %>') in your source code, and asp.net will convert that to panelInstance('TabContainer1$first$txt').
I told you to check the page source in the web browser just to see that the client Id was no longer "txt", but that it was constructed from the server ID and the naming container.
