Producing HTML wireframe in JDeveloper using Visual Web Designer

Question

Using 10.1.3.5 on winXP..
You'd think something as simple as an html wireframe could be easily accomplished using the visual editor... doesn't work at all. I create an html template, then create an html page from template... fine so far.
As soon as I try to insert a component from component palette in Design mode... it doesn't let me... there are no valid insertion points anywhere... all I want is to produce some quick screen mockups, basic wireframe for clients to test out and review.
Has anyone ever done this with Jdeveloper successfully?

Answer 1

You will get this error, when you don't have necessary web.config file entires related to ASP.NET Chart controls for that. Please verify those entries
Make sure that the following entries are there in your web.config file
<appSettings> 
  <add
key="ChartImageHandler"
value="storage=file;timeout=20;"
/> 
</appSettings> 
<compilation
targetFramework="4.0"> 
 <assemblies> 
  <add
assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> 
 </assemblies> 
</compilation> 
<system.webServer> 
<handlers> 
      <add
name="ChartImg"
verb="*"
path="ChartImg.axd"  type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,
System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"  /> 
    </handlers> 
</system.webServer> 
Also make sure that you've the following register directives
<%@ Register
Assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" 
    Namespace="System.Web.UI.DataVisualization.Charting"
TagPrefix="asp" %>
