In our application we get an ugly exception (parser) when having a string that contains a character like &.
For now we replace these characters using StringEscapeUtils.escapeXml(aLabel).
Is this the proper way because the label in our tableView shows the escaped character instead of a clean &
Thanks,
Vincent
The '&' character is used for the mnemonics in SWT/RAP/Tabris. They are usually used to mark a character in a menu or button with an underline for keyboard navigation.
On the Tabris clients for iOS and Android we don't display mnemonics, as we don't have a keyboard navigation as on the desktop - but they should cause no problems if they are set.
So, where does this exception happen?
On the server, the Android or iOS client?
Jordi, the exception happens in the server in the method getColumnText.
public String getColumnText( Object element, int columnIndex ) {
return text;
}
The exception happens when the text is a string containing '&' like in "Billy & Jean"
This is the exception:
Exception occurred
java.lang.IllegalArgumentException: Failed to parse markup text at org.eclipse.swt.internal.widgets.MarkupValidator.validate(MarkupValidator.java:60) at org.eclipse.swt.widgets.TreeItem.setText(TreeItem.java:978) at org.eclipse.jface.viewers.TreeViewerRow.setText(TreeViewerRow.java:176) at org.eclipse.jface.viewers.ViewerCell.setText(ViewerCell.java:162) at org.eclipse.jface.viewers.TableColumnViewerLabelProvider.update(TableColumnViewerLabelProvider.java:70) at org.eclipse.jface.viewers.ViewerColumn.refresh(ViewerColumn.java:155) at org.eclipse.jface.viewers.AbstractTreeViewer.doUpdateItem(AbstractTreeViewer.java:935) at org.eclipse.jface.viewers.AbstractTreeViewer$UpdateItemSafeRunnable.run(AbstractTreeViewer.java:103) at org.eclipse.jface.util.SafeRunnable$1.run(SafeRunnable.java:130) at org.eclipse.jface.util.SafeRunnable.run(SafeRunnable.java:177)
The exception you see does not come form tabris. It comes from RAP. I assume you are using tree/table.setData( RWT.MARKUP_ENABLED, Boolean.TRUE ); right?
When using markup only a subset of HTML is allowed, see http://download.eclipse.org/rt/rap/doc/2.2/guide/reference/api/org/eclipse/rap/rwt/RWT.html#MARKUP_ENABLED
So, when you are using markup and you want to have an & character you need to use it's entity: &
But please note: Basic markup is only supported in Tabris with version 1.4 (release 2014, June 26th)

I am trying to set up a MFC C++ App in Visual Studio 2019 such that modifies the user's text as they are typing.
Current layout is 2 radio buttons,
ID= rdbOn (set to Group = True, with Value int variable m_isOn = 1)
ID= rdbOff, m_isOn value would be = 0
and 1 Edit Control,
ID= txtInputBox, with Value CString variable m_inputString
Currently, for testing I can see how it would work for a button on click, it would take something like the following and just SetDlgItemText of the result. But that would be after they have typed, not WHILE they are typing.
void Onsomebtnclick()
{
//convert CString to String of m_inputString
//do some string manipulation
//convert back to CString
//SetDlgItemText(txtInputBox, result)
}
Update:
got EN_CHANGE to work
I was able to get EN_CHANGE working with the flag suggestion from user #GoGoWorx. However, now I just have a slight problem that the cursor is back to the beginning of the edit control txtInput.
I'm reading about using a CEdit::SetSel but don't know how to use that directly in my code. I tried
CEdit control MFC, placing cursor to end of string after SetWindowText
someDlg::someFunction()
{
//some logic stuff to get a result string
SetDlgItemText(txtInputBox, result);
//need it to set the cursor to the end
//I tried these, but it didn't recognize (expression must have class type?)
//txtInputBox.SetSel(0, -1);
//txtInputBox.SetSel(-1);
}
It sounds like you need to use the ON_EN_CHANGE message-map notification (called after the control has been updated due to typing or pasting for example)
BEGIN_MESSAGE_MAP(CMyDialog, CDialog)
ON_EN_CHANGE(IDC_EDIT_CONTROL, &CMyDialog::OnEnChangeEditControl)
END_MESSAGE_MAP()
void CMyDialog::OnEnChangeEditControl()
{
// Copy or call your Onsomebtnclick() here
}
I'm not sure what you're using for the numeric identifier for the edit control, since these are typically upper case defines - replace IDC_EDIT_CONTROL above with your define (possibly txtInputBox, but again, these are normally upper case, so I'm not sure).
Also change CMyDialog for the name of your dialog class too.
Note that we're using the ON_EN_CHANGE message-map handler here instead of the ON_EN_UPDATE, since the ON_EN_CHANGE message is sent after the control has been updated, whereas ON_EN_UPDATE is called just before it's updated.
The message-map handlers are described in the Remarks section of the CEdit control documentation: https://learn.microsoft.com/en-us/cpp/mfc/reference/cedit-class?view=msvc-160
Regarding your concern about modifying things as the user types - this should be fine, since every change (keystroke or paste from clipboard, etc.) should trigger this handler to be called, where you can change whatever you need. Just be sure that when you're updating the control, you don't trigger the ON_EN_CHANGE again and end up in a recursive 'change' loop.
You might be able to do this with some sort of flag to indicate you're the one updating the control, as opposed to the user, however it's probably better to subclass the CEdit control to do what you're wanting. There are a few examples out there of how to do this (it's not as difficult as it might sound), for example:
https://www.codeproject.com/Articles/27376/Avoiding-EN-CHANGE-notifications
I recently changed my domain objects from LocalDate to ZonedDateTime. I also created a brand new play JHipster application and one play entity choosing ZonedDateTime for two class members. The test application (new) works while my existing application does not, even after going through all the code twice. I loaded CSV data using Liquibase and my listing code shows the dates properly. Here's what the data looks like in my Maven output, e.g. entrydate='2017-02-23T19:53:18-05:00[America/New_York]', transaction='Initial Balance',
When I choose to update the date-time value with the "datetime-picker" in the dialog.html, a string date time is shown in the text box but when I push "Save" I get an "Internal Server Error" and the Maven output shows:
.HttpMessageNotReadableException: Could not read document: Text '2017-02- 26T00:53:18.000Z' could not be parsed at index 23 (through reference chain: org.ciwise.blackhole.domain.GenLedger["entrydate"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Text '2017-02-26T00:53:18.000Z' could not be parsed at index 23 (through reference chain: org.ciwise.blackhole.domain.GenLedger["entrydate"])]
Does anyone have an idea why the picker would produce String text in the text box that isn't acceptable when the HTTP PUT occurs (edit)?
My application does use Service classes but they handle the same Java domain objects as the JPA Repository classes do.
One more thing, the schema for the API shows e.g. "entrydate": "2017-02-23T21:44:04.859Z", but the actual JSON return is "entrydate": "2017-02-23T19:53:18.000-0500",
I'm hoping someone else has encountered this before.
Thanks

The answer here was to re-introduce application.yml. Inside this file it defines some Spring profiles but of most importance, it provides an option for Jackson serialization into JSON e.g.
jackson:
serialization.write_dates_as_timestamps: false
This resolved my issue.
I am trying to construct an anchor tag with a dynamic href attribute in Jade.
I did go through the docs and some SO questions but they didn't help me. This is what I tried.
a(href= "http://www.imdb.com/title/#{movie.imdb_id}") Know more
But it renders
http://www.imdb.com/title/#{movie.imdb_id}
rather than
http://www.imdb.com/title/tt1234567
However this works
a(href= "http://www.imdb.com/title/" + movie.imdb_id) Know more
and this too.
- var url = "http://www.imdb.com/title/" + movie.imdb_id;
a(href= url) Know more
What's wrong with the first version?
Interpolation is only available in text.
You need to use JS string concatenation for attributes:
a(href="http://www.imdb.com/title/" + movie.imdb_id) Know more
If you JavaScript runtime supports ES2015 template string, you can also use them (notice the backticks):
a(href=`http://www.imdb.com/title/${movie.imdb_id}`) Know more
Reference
the pug variable declaration doesnt work in this case using #{...}
the right syntax goes this way,
a(attributes) Know more
a(href="http://www.imdb.com/title/"+ movie.imdb_id) Know more
the attributes is an expression so it renders correcly, or you could use ES5 template literals with back quotes to render the variable along side the text which becomes
a(href=`http://www.imdb.com/title/${movie.imdb_id}`) Know more
note that when using back quotes with template literals your variable expression are enclosed in parenthesis and a leading $ sign, that is ${..expression..}
When you quote it simply tells pug "this is a string". That's basic JS. Interpolation works with #{'#{interpolation}'} too! is an example which renders "Interpolation works with #{interpolation} too!"
I don't have any knowledge about pug(jade)
But my guess is "a(your code)" is already a signal to pug(jade) that it is in the controller's scope already.. and "{variable}" is also an indicator that you are accessing controller's scope. so
a(href= "http://www.imdb.com/title/#{movie.imdb_id}") Know more
for "{}" inside a() is no longer an indicator that your are trying to access controller's scope because you're already in the controller's scope.. so "{}" inside a() is just a string, {movie.imdb_id} is part of the link string.
So in order for the framework to identity that movie.imdb_id is a variable, you should separate it from the actual string.
NOTE: This is just a guess..I'm using angular
I use richfaces 3.3.3.Final with Seam and facelet.
I have plugged a profiler on my application and I have a weird behavior.
When I log all exceptions thrown by the application, I have more than 10 000 NoSuchFieldElementException in 10 minutes.
After many search, I found the problem:
When I started an ajax request by a4j:support, the NoSuchFieldElementException is thrown by the AjaxChildrenRenderer in these lines (199-202):
String componentType = (String) component.getClass().getField("COMPONENT_TYPE").get(null);
result = _specialComponentTypes.contains(componentType);
The component variable is a UIInstructions and it has no "COMPONENT_TYPE" field. So, the exception is normal.
This exception is thrown for each html block contained in my page. For example:
<h2>Test</h2>
<span></span>
When I reRender a block with html tag, the exception is thrown.
I have very complex page, so I get many of this exceptions.
How I can do to avoid this exception ? May be a parser option to avoid to go in this class for html block.
Thanks for your help.
As a temporary solution, you could modify the source code to add an instanceof check which should skip that block and then ship the modified source code with your webapp. Ship it either as a single class with identical package/class name in web project itself (javadoc-document it properly), which would always have preference in classloading over the one in the JAR, or as a modified and rebuild JAR file.
if (!(component instanceof UIInstructions)) {
String componentType = (String) component.getClass().getField("COMPONENT_TYPE").get(null);
result = _specialComponentTypes.contains(componentType);
}
As a lasting solution, you should report it as a performance issue to the RichFaces guys so that they get it fixed and release a new update, but I don't think that they will prioritize 3.3.x updates that much. I.e. it might take longer than you'd expect.
I am working with a Windows Forms application in C# and Visual Studio 2005.
I am showing a message box within an button click event,
string messageBoxText = "Click OK to save your changes\n";
string caption = "Confirm Changes";
MessageBoxButtons button = MessageBoxButtons.OKCancel;
//Display the MessageBox
MessageBox.Show(messageBoxText, caption, button);
MessageBoxResult result = MessageBox.Show(messageBoxText, caption, button);
The following error pops up on compilation:
Error 1 The type or namespace name 'MessageBoxResult' could not be found (are you missing a using directive or an assembly reference?)
Also, IntelliSense does not show any such thing as MessageBoxResult. I have seen this statement on MSDN. How to capture the response of the message (OK/Cancel) without using MessageBoxResult?
The MessageBoxResult Enumeration is only available on .NET 3.0+. You're using 2.0.
Use DialogResult as Walt suggested.
You could try placing
using System.Windows;
at the top of your source.
Or try DialogResult instead. That's in the System.Windows.Forms namespace, and is what Show() returns in my C# source files...
First Add Reference PresentationFramework (best from NuGet) and make using System.Windows;. Then You must use System.Windows from PresentationFramework for MessageBoxResult.
Second make using Microsoft.Win32; and pick it up for SaveFileDialog.
