problems with getURL in CVS build
Hi all,
in my mapping applications I make extensive use of getURL() to load map
data to the current map extent. I don't load complete XML files, but
just chunks of SVG or XML.
It worked fine in the Batik 1.5.1 official release, but does not work in
the current CVS version. I don't know why. Using the debugger, I see
that in the callback function of getURL() it returns data.success with
"false" which was not the case in the 1.5.1 release (there it returned
"true").
Here is my JS code:
function getLayers() {
myMainMap.nrLayerToLoad = 0;
for (i=0;i<myMainMap.dynamicLayers.length;i++) {
if (myMainMap.dynamicLayers[i].value == "yes") {
myMainMap.nrLayerToLoad++;
if (myMainMap.nrLayerToLoad == 1) {
document.getElementById("loadingData").setAttributeNS(null,"visibility","visible");
}
var myUrlString =
"sendGeom.php?layername="+myMainMap.dynamicLayers[i].key+"&xmin="+myMainMap.curxOrig+"&ymin="+((myMainMap.curyOrig
+ myMainMap.curHeight)*
-1)+"&xmax="+(myMainMap.curxOrig+myMainMap.curWidth)+"&ymax="+(myMainMap.curyOrig
* -1);
getURL(myUrlString,addGeom);
}
}
}
//add the geometry to the application
//note that empty groups in the main-map have to exist
function addGeom(data) {
if(data.success) {
var node = parseXML(data.content, document);
var curDynLayer =
node.firstChild.getAttributeNS(null,"id").replace(/_tempGeometry/,"");
var myGeometryToAdd = document.getElementById(curDynLayer);
if (myMainMap.dynamicLayers[curDynLayer].loaded == "yes") {
var tempGeometry =
document.getElementById(curDynLayer+"_tempGeometry");
myGeometryToAdd.removeChild(tempGeometry);
}
myGeometryToAdd.appendChild(node);
//call function to place names
if (curDynLayer == "elevation") {
placeLabels(curDynLayer);
}
myMainMap.dynamicLayers[curDynLayer].loaded = "yes";
myMainMap.nrLayerToLoad--;
if (myMainMap.nrLayerToLoad < 0) {
alert("error: this shouldn't be happening...!
layercontext: "+curDynLayer);
}
if (myMainMap.nrLayerToLoad == 0) {
document.getElementById("loadingData").setAttributeNS(null,"visibility","hidden");
}
var myStatusString =
document.getElementById(curDynLayer+".Data").getAttributeNS(cartoNS,"nrRecs");
statusChange("loaded "+myStatusString+" elements for
layer "+curDynLayer+"!");
window.setTimeout("statusChange('map ready')",3000);
}
else {
alert("something went wrong with dynamic loading of
geometry!");
}
}
The full code is available at
http://www.carto.net/williams/yosemite/loaddata.js - the application is
available at http://www.carto.net/williams/yosemite/loaddata.js - if you
use the debugger, you'll see that in the file "loaddata.js" in the
function "addGeom(data)" that "data.success" evaluates to false.
Did something in Batik change or is it a matter of wrong document
encoding? Do I need to load full XML documents including a valid XML
header instead of just "chunks"?
Thanks for any idea what might be wrong here.
Andreas

yes, the content sent back was gziped with Apache mod_gzip - that
explains it!

thank you! it's not that urgent - enjoy your weekend!
I'll try the postURL support with my digitizing app

The problem was with the gziped content. I'll commit a
fix either tonight or over the weekend.
BTW there is some totally untested postURL support in the
current CVS build.
