<DIV></DIV>We had a similar challenge here, one of our web programmers helped me
figure this out.<BR>In this situation, I wanted all layers with a name that did
NOT include "Balance", "Ratio", or "Highlight" to appear in this
layercontainer:<BR><BR>loader: {

filter: function(record)

var myarr = new
Array();<BR>
myarr[0]=record.get("layer").name.indexOf("Balance");<BR>
myarr[1]=record.get("layer").name.indexOf("Ratio");<BR>
myarr[2]=record.get("layer").name.indexOf("Highlight");<BR>
<BR>
if(myarr[0]==-1 && myarr[1]==-1 &&
myarr[2]==-1){<BR>
return
true;<BR>
}else{<BR>
return
false;<BR>
}<BR>
}<BR><BR>Not sure if it's THE best solution, but it does work and it's fairly
simple to add additional words to search for. <BR>Hope this helps,

<DIV>I am faily new to GeoExt and openlayers. What I am trying to do is add
multiple filters to a layercontainer so that I can add multiple layers to each
group. Not sure if this is the best way to do this but what I want to do is
add all my Street Labels to a group called "Labels" I can add one no problem
called Overview Streets with the following code, but I need to add additional
layers like one called Quadrant Streets. When I try to modify the filter code
to add additional names it doesn't work and I get javascript errors. Any help
appreciated!</DIV>
