As part of an effort to port an existing application to also work on Adobe ColdFusion we are having problems with the following code.

According to the documentation you should be able to search for structs

<cfscript>
fields = [{"name":"title"},{"name":"main_image"},{"name":"layout"},{"name":"teaser"},{"name":"main_content"},{"name":"sidebar_content"},{"name":"active"}];

writedump(fields); // should have 7 items

for ( field in fields ) {
	if (field.name == "layout") {
		arraydelete(fields, field);
	}
}

writedump(fields); // should now have 6 items
</cfscript>

Hi Alex, I agree this should work, and have voted. Meantime, perhaps this would work? <cfscript> fields = [{"name":"title"},{"name":"main_image"},{"name":"layout"},{"name":"teaser"},{"name":"main_content"},{"name":"sidebar_content"},{"name":"active"}]; fieldsTempWorkaround = fields.duplicate();//temporary workaround for CF-4197153 writedump(fields); // should have 7 items for ( field in fieldsTempWorkaround ) { if (field.name == "layout") { arraydelete(fields, field); } } writedump(fields); // should now have 6 items </cfscript> Thanks!, -Aaron

Following Code would work: <cfscript> fields = [ {"name":"title"} , {"name":"main_image"} , {"name":"layout"} , {"name":"teaser"} , {"name":"main_content"} , {"name":"sidebar_content"} , {"name":"active"} ]; writedump(fields); // should have 7 items arraydelete(fields, {"name":"layout"}); writedump(fields); // should now have 6 items </cfscript> ArrayDelete is working fine. But deleting elements while looping through it would throw ConcurrentModificationException. Hence not a bug and closing it .
