seam - Check for validation errors in part of a form in JSF -

-

i'm building seam application, huge form divided different parts, or modules. need way figure out when module "complete", meaning validation fields in module passes. need in view, setting css-class or whatever.

something like:

<a:region id="region1">     <s:div styleclass="#{invalid ? 'errors' : ''}">        <h:inputtext required="true" id="input1" />        <h:inputtext required="true" id="input2" />        <h:commandbutton value="save section" rerender="region1" />     </s:div> </a:region>

i figured had 2 options:

  • using sort of view-logic (like #{invalid} single field)
  • using method in bean, components module programmatically, , check them validation errors.

however, can't find way of them. ideas if possible?

we're using jsf 1.2 seam.

thanks.

you can use uiinput#isvalid() check if validation error has occurred on particular input component.

<s:div styleclass="#{!input1.valid or !input2.valid ? 'errors' : ''}">    <h:inputtext binding="#{input1}" required="true" id="input1" />    <h:inputtext binding="#{input2}" required="true" id="input2" />    <h:commandbutton value="save section" rerender="region1" /> </s:div>

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...
