Attribute 'for' of label component with id xxxx is not defined

I got the warning in the log file when I have used the tag <h:outputLabel> without attribute " for " in xhtml file. It was really polluting my server log files. The logged information actually makes sense anyway! We could find an answer as the following: "Having h:outputLabel without a "for" attribute is meaningless. If you are not attaching the label, you should be using h:outputText instead of h:outputLabel." However, these solutions are not possible just for my situation. Instead of using h:outputText for only displaying text, my team has used h:outputLabel too many places. We were nearly in our release time (next day) so it is quite risky and takes much efforts if we try to correct it. Because the style (with CSS) is already done with h:ouputLabel . The alternative by adding attribute " for " the existing h:outputLabel is not reasonable either. I really need to find another solution. Fortunately, I came across a way if I cha...

Styling Sort Icons Using Font Awesome for Primefaces' Data Table

So far, Primefaces has used image sprites for displaying the sort icons. This leads to a problem if we want to make a different style for these icons; for example, I would make the icon "arrow up" more blurry at the first time the table loading because I want to highlight the icon "arrow down". I found a way that I can replace these icons with Font Awesome icons. We will use "CSS Pseudo-classes" to achieve it. The hardest thing here is that we should handle displaying icons in different cases. There is a case both "arrow up" and "arrow down" showing and other case is only one of these icons is shown. .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s { background-image: none; margin-left: 5px; font-size: 1.1666em; position: relative; } .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s:not(.ui-icon-triangle-1-s)::before { content: "\f106"; font-family: "FontAwesome"; position: ...

Separate Constructing a System from Using It

I n the real world, in order to use a building (hotel, supermarket, etc) we need to construct it first. This concern should be applied for software development as well. Step by step, I would like to show you the issue about no separation of constructing and using it and then I'll give you some approaches to overcome this issue. | Note : you can find the  below  demonstrated code here    Take a Look the Following Simple Application Used tools and technologies: Eclipse (Mars), JDK 1.8 I had an App which uses Controller . Controller uses Service (an interface). Finally, Service has one concrete class is DefaultService . //package vn.nvanhuong.system.separationconstructing; public class App { public static void main(String[] args) { Controller controller = new Controller(); controller.doAction(); } } public class Controller { private Service service; public void doAction(){ System.out.println("doAction in Controller"); getService().execut...

Junit - Test fails on French or German string assertion

In my previous post about building a regex to check a text without special characters but allow German and French . I met a problem that the unit test works fine on my machine using Eclipse, but it was fail when running on Jenkins' build job. Here is my test: @Test public void shouldAllowFrenchAndGermanCharacters(){ String source = "ÄäÖöÜüß áÁàÀâÂéÉèÈêÊîÎçÇ"; assertFalse(SpecialCharactersUtils.isExistSpecialCharater(source)); } Production code: public static boolean isExistNotAllowedCharacters(String source){ Pattern regex = Pattern.compile("^[a-zA-Z_0-9_ÄäÖöÜüß áÁàÀâÂéÉèÈêÊîÎçÇ]*$"); Matcher matcher = regex.matcher(source); return !matcher.matches(); } The result likes the following: Failed tests: SpecialCharactersUtilsTest.shouldAllowFrenchAndGermanCharacters:32 null A guy from stackoverflow.com says: "This is probably due to the default encoding used for your Java source files. The ö in the string literal in the J...

No difficulties, no discovery

Bill Gate had said that “I choose a lazy person to do a hard job. Because a lazy person will find an easy way to do it.” In my opinion, that remark is so true in some cases. My team has tried to apply integration tests for our projects. Firstly, we had meeting to figure out what problems we met. Then, we decided to create a new project that is similiar to the current one and we called it a prototype project. Yeah, I and some members were reponsile for it. I spent a lot of time and took a lot of efforts for coppying the current project because its domain logic was really complicated. What a boring task! I smelt a rat and felt too lazy. At that time, I thought that I need a change. I discussed with others: "Why don't we just create a branch of curent project and work on it?".  We didn't need spending time for coppying anymore. Just forked it and modified on it. Therefore, it was really a good solution. Leave your comments about that. ;)
