validation problem with JSF h:form and PrimeFaces p:dialog -

-

i have jsf page create form. form consists of variety of input fields , list of sub-elements.

to add sub-element, click "add element" link pops dialog box using primefaces p:dialog tag. it's similar login panel demo on prime faces page here, complete p:growl validation messages:

http://www.primefaces.org/showcase/ui/dialoglogin.jsf

my problem is, when click "add" in dialog box see growl validation messages fields in dialog box , fields on main form. want see messages dialog box.

is there way this? tried embedding form within form, didn't work. is, tried ...

<h:form>    <p:messages /> <!-- show validation messages create form contents -->    <h:inputtext value .../>    <h:datatable value .../> <!-- list of sub elements -->    <h:commandlink "shows add element dialog" ... />    <p:growl /> <!-- shows validation messages dialog contents -->    <p:dialog>       <h:form>         <h:inputtext value .../>         <p:commandbutton "validate dialog box fields add item list" .../>       </h:form>    </p:dialog>  </h:form>

... didn't work. appreciated!

first of cannot embed 1 form in another. think not valid html.

p:growl behaves h:messages. shows messages elements of page (not limited 1 form). can limit global messages (messages no id) setting globalonly="true" attribute.

change commandbutton update p:growl , make sure ajax request fired commandbutton (ajax=true). p:commandbutton has ajax=true default behaviour. if didn't change explicitly, ajax request.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
