I have got the same error (Exception... "Component returned failure code:

And I have found another solution:
Do NOT call "this._object.send(vData);"
if "this._object.abort();" has been called (see XMLHttpRequest.js).
-----------------------
Look at Request.js:
window.setTimeout(function(){
if (request._aborted !== true) {
request.send(config.data);
}
}, 0);
and look at XMLHttpRequest.js :
cXMLHttpRequest.prototype.send = function(vData) {
// Add method sniffer
if (cXMLHttpRequest.onsend)
....
and look at XMLHttpRequest.js:
cXMLHttpRequest.prototype.abort = function() {
....
// BUGFIX: Gecko - unnecessary DONE when aborting
if (this.readyState> cXMLHttpRequest.UNSENT)
this._aborted = true;
this._object.abort();
....
-----------------------
I have added to XMLHttpRequest.js these lines and the problem was solved:
cXMLHttpRequest.prototype.send = function(vData) {
if (!!this._isAbortCalled)
return;
....
cXMLHttpRequest.prototype.abort = function() {
this._isAbortCalled = true;
....
---------------------
I.e.
try { this._object.send(vData); } catch (e) {}
looks like a workaround.
What do you think?
Could you check my changes on your system if it solves your problem?
Hi
Is the problem reproducible on one of the OpenLayers examples?
(http://www.openlayers.org/dev/examples)
What version of OpenLayers do you use? Do you have the problem with
OpenLayers trunk?
XMLHttpRequest.js already includes a state variable to know if abort()
has been called, namely _aborted. But abort() sets _aborted to true
only if the XHR status is greater than UNSET. Could you try to have
abort() unconditionally set _aborted to true and see if that fixes it?
Thanks.
Hi
-------
It looks like the problem is reproducible here :
http://www.openlayers.org/dev/examples/getfeature-wfs.html :
POST
http://www.openlayers.org/dev/examples/proxy.cgi...p%3A%2F%2Fv2.suite.opengeo.org%2Fgeoserver%2Fows
POST
http://www.openlayers.org/dev/examples/proxy.cgi?url=http%3A%2F%2Fv2.suite.opengeo.org%2Fgeoserver%2Fows
Aborted
OpenLayers.js (line 969)
- that is from Firebug console.
- there is ".send..." method;
then I have manually wrap "this._object.send(this._data);" with
"try{..}catch(e){alert(e)}" and have got this exception :
[Exception... "Access to restricted URI denied" code: "1012" nsresult:
"0x805303f4 (NS_ERROR_DOM_BAD_URI)" location:
"file:///media/TMP/tmp_shara/OL-ex/getfeature-wfs_files/OpenLayers.js
Line: 11177"]
So seems I have done something wrong.
-------
We use 2.10 (stable) version of OpanLayer.
-------
The problem occurred right in the case XHR status is NOT greater then
UNSENT (on abort() call).
I have removed my fix and have commented this line:
if (this.readyState > cXMLHttpRequest.UNSENT)
- this also fixes the problem: checked on FF3.6.17+ubuntu;
F3.6.17+winXP; IE8+winXP ;
- BUT that line is marked as "BUGFIX" !
- I have also found a strange side effect at IE (! but NOT at FF)
(after commenting that line) : ... but seems that is completely another
problem and most probably it does NOT relate to current ticket:
"this.blocks.length" is null or not an object Framed.js, line:140
character 24
Thanks.
