<p class=MsoNormal>I’ve been pulling my hair out trying to get the
attached code to work with ExtJS v3.0.0. It works fine with 2.2.1 but I
get the following error with 3.0.0: <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Error: this.el is undefined<o:p></o:p></p>
<p class=MsoNormal>Source File:
http://extjs.cachefly.net/ext-3.0.0/ext-all-debug.js<o:p></o:p></p>
<p class=MsoNormal>Line: 40920<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve narrowed it down to the following bits (below the
sig). “selFeatCtl”—in addition to being used as the selectControl
for the FeatureSelectionModel in the GridPanel—is also used as the
control for a GeoExt.Action (not shown below but is in the attached code).
The code works under 3.0.0 if I just use the plain GeoExt.grid.FeatureSelectionModel()
constructor for the sm in the GridPanel (but of course then the featurehighlighted
handler doesn’t work).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any help is greatly appreciated,<o:p></o:p></p>
