Re: [Tobago] PageRendererBase warning

Hi Hani,

with which browser version do you get this warning exactly? Only with FF 4.0.1?

Hi,

We could reproduce the warning by selecting the same items to performe an 
action.

Test page:

<%@ taglib uri="http://java.sun.com/jsf/core"; prefix="f"%>
<%@ taglib uri="http://java.sun.com/jsf/html"; prefix="h"%>
<%@ taglib uri="http://myfaces.apache.org/tobago/component"; prefix="tc"%>

<f:view>
     <tc:page id="statusbar">

         <tc:panel>
             <f:facet name="layout">
                 <tc:gridLayout rows="20px;*" columns="222px;*" margin="0" 
cellspacing="0" />
             </f:facet>

             <tc:panel>
                 <f:facet name="layout">
                     <tc:gridLayout rows="*" columns="160px;*" />
                 </f:facet>

                 <tc:selectOneChoice id="selector"
                                     value="#{controller.selectedItem}">
                     <f:facet name="change">
                         <tc:command id="changeAction" 
action="#{controller.doSomething}"  />
                     </f:facet>
                     <tc:selectItems value="#{controller.items}" />
                 </tc:selectOneChoice>
                 <tc:panel />
             </tc:panel>

             <tc:panel />

             <tc:cell spanX="2" />

         </tc:panel>
     </tc:page>
</f:view>

Betreff: Re: [Tobago] PageRendererBase warning

Hi,

I found this warning often in our customers log file too, but I wasn't able to
reproduce it myself. I had a look in tobago.js and found this code:

getAbsoluteLeft: function(element) {
      var left = 0;
      var parent = false;
      while (element&&  element.offsetParent) {
        left += element.offsetLeft;
        left -= element.scrollLeft;
        if (parent&&  element.currentStyle) {  // IE only
          left += element.currentStyle.borderLeftWidth.replace(/\D/g, "") - 0;
        }
        element = element.offsetParent;
        parent = true;
      }
      return left;
    }

I'm not sure, if it's correct for all browsers and if the page content is 
scrolled.

Regards,
Helmut

Hello,

Sometimes we got a warning from PageRendererBase class while calling an
action. In contrast to firefox, internet explorer don`t produce this
warning.
I found out, that by decoding the requested page the request parametr
"actionPositionString" contains negative pixel values.
I don`t know what that means and why.

Log:
WARN org.apache.myfaces.tobago.renderkit.PageRendererBase - Can't
analyse parameter for action-position
java.lang.IllegalArgumentException: Can't parse to any measure: '-12px'
at org.apache.myfaces.tobago.layout.Measure.parse(Measure.java:39)

Env:
Tabago Version: 1.0.30
MyFaces: 1.1.7
FireFox: 4.0.1
IE: 6.0
