removeData failing on line 1821 using "in" on true which is not an object

[[email protected]…]

Using the Edge version of jQuery I'm getting an error on line 1821 in function removeData

the line in question is } else if ( name in thisCache ) { (put in context below)

In this case thisCache === true which is not an object so cannot have the in keyword applied to it.

Browsers Tested Firefox 6.0.2 Chrome 14 IE 9

Steps to reproduce: Navigate to ​http://jsfiddle.net/dwat001/SYQJA/20/show/ Click on one of the markers on the map in the resulting infoWindow mouseover one of the small images Move mouse out of larger image ERROR

Line in context: Support space separated names if ( jQuery.isArray( name ) ) { name = name; } else if ( name in thisCache ) { name = [ name ]; } else { split the camel cased version by spaces name = jQuery.camelCase( name ); if ( name in thisCache ) { name = [ name ]; } else { name = name.split( " " ); } }

Can you create a reduced test case? How did thisCache get to be true?

Because we get so many tickets, we often need to return them to the initial reporter for more information. If that person does not reply within 14 days, the ticket will automatically be closed, and that has happened in this case. If you still are interested in pursuing this issue, feel free to add a comment with the requested information and we will be happy to reopen the ticket if it is still valid. Thanks!

Hi Sorry for the delay in updating this, I have created a fiddle which is far more cut down at ​http://jsfiddle.net/dwat001/yrdX9/13/ the HTML is still complex (produced by google maps then inspected and cut down by hand) the error still occurs at the same point.

To reproduce navigate to ​http://jsfiddle.net/dwat001/yrdX9/13/show/ mouse over image in white info box, on mouse out you will see this error.

looking at the function removeData the parameter elem appares to be an event so

isNode = elem.nodeType, See jQuery.data for more information cache = isNode ? jQuery.cache : elem,

sets cache to elem. as you can see below elem has a property for a jQueryId and its value is true.

I'm not sure if this is valid or not, just reopening as a reminder to look deeper tomorrow

$("#floating-image").mouseleave(function(image) {

An event handler gets an event object, not a reference to the element.

compleate: hideZoomImageNow

That is not the correct spelling of "complete".

Please ask for help in the forums if you need it.
