    <p>I am getting a wierd problem and i am stuck on it for atleast 4 hours now. Actually i had written my code in a controller for testing but when i have moved the code to service i am getting a strange behaviour that the methods in service are not returning or may be methods that are calling them in the service only are not receiving .</p> <pre><code>class FacebookService implements InitializingBean, GroovyInterceptable { def getUserLikes(def at){ List&lt;String&gt; listOfUrls = [] String basicFbUrl = "https://graph.facebook.com/" String likeUrl = basicFbUrl + "me/likes?access_token=${at}" URL url = new URL(likeUrl) String jsonResponse = getResponseFromUrl(url) println "JSON RESPONSE IS ${jsonResponse}" // this is showing null } String getResponseFromUrl() { String something String resp = null; HttpURLConnection conn = (HttpURLConnection) url.openConnection(); try { int respCode = conn.responseCode if (respCode == 400) { log.error("COULD NOT MAKE CONNECTION") BufferedReader br = new BufferedReader(new InputStreamReader(conn.getErrorStream())); def jsonResp = JSON.parse(br.text) } else { resp = conn.getInputStream().getText() } } finally { conn.disconnect() } println("RETURNIG RESPONSE ${resp}") // This returns me a map as expected return resp; } </code></pre> <p>Dont know where does resp goes ?? any suggestions please ?? OK i know the culprit , i am posting the code of invokeMethod</p> <pre><code>def invokeMethod(String name, args){ System.out.println("IN INVOKE METHOD NAME ${name}") if(facebookPalsCache==null) facebookPalsCache = new FacebookPalsCache(1000) System.out.println("time before ${name} called: ${new Date()}") //Get the method that was originally called. def calledMethod = metaClass.getMetaMethod(name, args) System.out.println("CALLED METHOD IS ${calledMethod}") //The "?" operator first checks to see that the "calledMethod" is not //null (i.e. it exists). if(name.equals("getFriends")){ println "getFriends..." def session = RequestContextHolder.currentRequestAttributes().getSession() def friends = facebookPalsCache.get(session.facebook.uid) if(!friends){ def getFriends = facebookGraphService.invokeMethod (name, args) println "Saving FBFRIENDS in CACHE" facebookPalsCache.put(session.facebook.uid, getFriends) return getFriends } else return friends } else { if(calledMethod){ System.out.println("IN IF AND INVOKING METHOD ${calledMethod}") calledMethod.invoke(this, args) } else { return facebookGraphService.invokeMethod(name, args) } } System.out.println "RETURNING FROM INVOKE METHOD FOR NAME ${name}" System.out.println("time after ${name} called: ${new Date()}\n") } </code></pre> <p>OK SOMETHING IS WRONG ABOVE I DONT KNOW WHAT CAN ANYONE PLEASE HELP ??</p>

    2. COYou must have something else named `methodB` in the visibility scope. A closure, a variable, whatever. +1 for actual code.

    3. COhi victor , tim : sorry for late response but there;s nothing as such.. just that from a UtilController i am calling the service methodA and from that methodA in the service i am calling another method which is methodB . Now all is well till methodB returns something , its not available in methodA , but if i write the methodB in UtilController , i get the return value.. I thought it had something to do with my service since it implements InitializingBean, GroovyInterceptable

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
