java - How to access javax.faces.PROJECT_STAGE from the view/inside code? -


[मेरा सेटअप: जावा ईई 6 आवेदन, ईजेबी 3.1, सीडीआई / वेल्ड, जेएसएफ 2, ग्लासफ़िश 3.0.1 पर चल रहा है)

मैं सिर्फ फीस प्रोजेक्ट स्ट्रेज पर पढ़ता हूं, जो एक अच्छी बात है इसलिए मैंने इसे मेरी वेब। एक्सएमएल में इसे डिज़ाइन करने के लिए कॉन्फ़िगर किया है: 

  & lt; context-param & gt; & LT; परम-नाम & gt; javax.faces.PROJECT_STAGE & lt; / परम-नाम & gt; & LT; परम-मूल्य & gt; विकास & lt; / परम-मूल्य & gt; & Lt; / संदर्भ param & gt;

अब मैं JSF दृश्य से प्रोजेक्ट स्टैज का उपयोग करना चाहता हूं (तदनुसार विशिष्ट UI घटकों की दृश्यता सेट करना)।

इसलिए मैंने पहले से ही एक आउटपुट टेक्स्ट मान # {javax.application.projectStage} , जो रिक्त लगता है, और मैंने भी कई अन्य रूपों की कोशिश की, बिना सफलता के। मैं भी जावा कोड के भीतर से ProjectStage का उपयोग करने के लिए प्रबंधित नहीं है (फिर मैं एक बीन के साथ खुद को बेनकाब कर सकता हूं)।

मैं अपने आवेदन के अंदर PROJECT_STAGE मान कैसे प्राप्त कर सकता हूं?

समझे। दृश्य से, इसे यहां तक ​​पहुंचा जा सकता है: 

  & lt; h: आउटपुट टेक्स्ट वैल्यू = "स्टेज: # {facesContext.application.projectStage}" / & gt;

कोड में, इसे यहां तक ​​पहुंचा जा सकता है: 

  FacesContext.getCurrentInstance ()। GetApplication ()। GetProjectStage ()। ToString ()

php - How to paginate multiple results in CakePHP? -

How can I use the Pageinization Assistant in KPHPH to set more than one result on the same page? They will do the page independently Edit: I have found a reason why it can not do this because because the page will get its URL from the assistant controller / verb and after that Finally add its parameters. If it pulls the URL from the address bar, it has its own unique variable and then a straw_rele is used to navigate to the next one if you have already placed the page, or if it is not present in it Now, I'm thinking of re-writing assistant to support this feature to support this feature, but I'm not sure if I need it or if they are already I support it and I am doing it wrong Here's my solution in your controller: function index () {// your default model is $ $ this- & gt; Set ('model1', $ this- & gt; paginated)); // Endorsement for Model 2- $ this- & gt; Set ('Model2', $ this- & gt; Paginated ('Model2')); } In your ...

wpf - Converter stops filter working -

I'm trying to display the file name in a listbox, taken from a special directory. They are stored in an ObservableCollection of FileInfo Object: Public supervision & lt; FileInfo & gt; Project Files {Get (empty (selected folder == empty); DirectoryInfo D = New Directory Info (SelectedFolder); if (!
