JavaScript Error When Dragging Over SELECT

apptaro Feb 29, 2008 3:44 AM

Please try the following:

<h:selectOneMenu>
<f:selectItem itemValue="option"/>
</h:selectOneMenu>
<a4j:outputPanel>
<rich:dragSupport dragType="myType"/>
<h:outputText value="DRAGME"/>
</a4j:outputPanel>

JavaScript error occurs when dragging over the select.
Happens for IE6, but not for Firefox 2.

How can I fix this?

I tested with MyFaces Core 1.1.3 + RichFaces 3.1.4GA, and JavaScript error occurs.

Just to clarify, I don't need to drop on the select.

I use dragSupport/dropSupport and selectOneMenu on the same page,
so when I drag things, the cursor occasionally gets over the select and JavaScript error occurs.
I just want this error not to happen.

You shure it isn't prototype versions conflict?

No, error occurs without using prototype.js.
Only the above code is sufficient to reproduce the issue.

This probably is a bug, but I found I can workaround it, by defining a dragIndicator.

<h:selectOneMenu>
<f:selectItem itemValue="option"/>
</h:selectOneMenu>
<rich:dragIndicator id="indicator"/>
<a4j:outputPanel>
<rich:dragSupport dragType="myType" dragIndicator="indicator">
<rich:dndParam name="label"><h:outputText value="DRAGME"/></rich:dndParam>
</rich:dragSupport>
<h:outputText value="DRAGME"/>
</a4j:outputPanel>

This code does not product JavaScript error.
