having big trouble with evalJSON() - am I really at war with it?
Based on the example from Hugo Palma (see http://markmail.org/message/4bdwo2yrx6tavdgh)
I implemented a dependend checkbox.
Event handling is fine, but I lost hours finding out while
response.evalJSON() fails and I still have no clue...
Im always getting this erreor;
Error communication with the server: Result of expression
'response.evalJSON' [undefined] is not a function.
Looks like evalJSON ist not defined (I'm not a JavaScript guy at
all....)
How do I import the js library that includes the evalJSON function? I
tried everithing I can think of and this is my
current js import
@IncludeJavaScriptLibrary( { "context:js/Chenillekit.js", "context:js/
RESelection.js", "${tapestry.scriptaculous}/prototype.js" })
public class RealEstateCreate {
Any help is VERY welcome, as I'm at a dead end now....
Thanks, Max
This are the js, tml and class files
---------- RESelection.js ---------
function onCompleteChangeReSubType(response) {
selectElement = $('resubtype');
Tapestry.debug(response);
Tapestry.debug("1");
responseJSON = response.evalJSON();
Tapestry.debug("2");
while (selectElement.options.length > 0) {
selectElement.options[0] = null;
}
for (index = 0; index < responseJSON.length; index++) {
selectElement.options[index] = new Option(responseJSON
[index].label, responseJSON [index].value);
}
Tapestry.ElementEffect.highlight($("resubtype"));
}
