I have to form a custom tag which has the following format.
 
 
<project:multiselect title="Title">
  <project:available search="true">
  <option value="1999">1999</option>
   ...available can have html:option, html:options, html:optionsCollection...
  </project:available>
 <project:selected search="false">
  <option value="2000">2000</option>
  ...selected can have html:option, html:options, html:optionsCollection...
 </project:selected>
</project:multiselect>
 
Error 500--Internal Server Error
