I am trying to add an "onfocus" attribute to an input coming out of a form which I have made using the forms module of WebManager.

In the standard formPart.jspf you need to use the following variable 

 ${formPart.content}



to call the content of the form model (coming out of the forms module) which generates the HTML for eg. an input. The problem is that I cannot influence the HTML which is generated. 

 <input class="normalclass" type="text" value="Uw gebruikersnaam" maxlength="250" style="" name="f79461" size="20"/>



To make a long story short; I want to achieve something like the following:

 <input class="normalclass" type="text" value="Uw gebruikersnaam" maxlength="250" style="" name="f79461" size="20" onfocus="this.value=''" />

What you can do is not use the formPart.content but write the content yourself. An example (for a text input):


<c:choose>
  <c:when test="${wmfn:instanceOf(formPart, 'nl.gx.webmanager.cms.form.FormPartText')}">
  <input type="text" maxlength="${formPart.maxLength}" name="${formPart.identifier}" value="${formPart.prefilling}" class="${formPart.styleOptions}" />
	</c:when>
<c:otherwise>etcetc</c:otherwise>
</c:choose>



You can (ab)use any available fields in forms module you don't need (help text, additional text) for adding attributes the forms module doesn't provide.
