jquery - jsf 2.0 working with javascript prevents ajax call -

-

i'm working on jsf 2 project. got javascript/jquery functions on client side, after calling these functions <a4j:commandbutton> not working. 

servlet.service() servlet faces servlet threw exception: java.lang.nullpointerexception      @ com.sun.faces.context.partialviewcontextimpl.createpartialresponsewriter(partialviewcontextimpl.java:441)

if change <a4j:commandbutton> <h:commandbutton>, works fine, need a4j because of oncomplete attribute.

how can debug issue? looks problem javascript event, prevents ajax call.

i have tracked down problem determine due <button> tag being in html.

for example:

<!doctype html> <html lang="en"  xmlns="http://www.w3.org/1999/xhtml"  xmlns:h="http://java.sun.com/jsf/html"  xmlns:a4j="http://richfaces.org/a4j"> <h:head> </h:head> <h:body>     <h:form id="example">         <a4j:commandbutton type="submit" value="submit" />         <button>button</button>     </h:form> </h:body> </html>

my theory javascript submitting ajax somehow confused <button> tag in ie7 causing invalid post server.

without seeing html, can't issue.

check following jira posts more information.

http://java.net/jira/browse/javaserverfaces-2666

https://issues.jboss.org/browse/rf-12693

pavol pitonak on @ richfaces discovered if add name attribute <button> error go away.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
