I have a datagrid which is editable and I need to send that back to the database via a CFC for insertion into the database after all the editing is complete. Dumping the array collection to cfdump tells me that I have an array with items and a structure but i cannot understand how to "loop" through each and insert into the DB. There see...
I have an application.cfc in a subdir of my webroot: /app/application.cfc I recently added another application.cfc in a subdir of that and it extends the original application.cfc using the proxy method described here http://corfield.org/blog/index.cfm/do/blog.entry/entry/Extending_Your_Root_Applicationcfc : /app/mysubdir/application....
Hey Guys, I'm having a tad of an issue dealing with Dynamic Variable Names. What is happening is I have a CFC that builds part of form for me using some data in a table. Then the cfc sends the form's code back to the page as a string. Well I need to assign values to these form fields so people don't overwrite the data. I'm pulling the da...
How do I reset a Coldfusion Application / application.cfc without resetting the Coldfusion Server instance? If I remember right, there are a few tricks out there such as creating a reinit function within application.cfc or renaming the file. ...
In a Coldfusion component / CFC, I want to properly scope some variables to be available for all contained functions, but to be hidden or blocked from outside scripts. What is the name of the cfc's memory scope? Is it 'variables'? Is that available inside a contained function? Is it blocked from outside the cfc? (Examples in CF 8) Call...
I have a fairly long cfc file, about 1800 lines long, that worked fine in ColdFusion 8, but after upgrading my development system to ColdFusion 9 and doing some testing I get a compile error for a cfc and the message says "Branch target offset too large for short". I modified the file to eliminate some unused functions and consolidated o...
How do I post a form using jQuery.post() to a Coldfusion.cfc method and return json data? Is there a certain way I need to format the url or form values in order to specify the cfc method to invoke remotely? How do I tell Coldfusion to return json data? I've searched the existing jQuery/Coldfusion.cfc questions and I'm looking for some ...
How do I invoke a static method on a CFC without using cfinvoke? I know that I can do this: <cfinvoke component="MyComponent" method="myStaticMethod' arg1="blah" returnvariable=myReturnVar> I would like to be able to invoke this method the same way I would a UDF: <cfset myReturnVar = MyComponent.myStaticMethod(blah)> This, however...
I have a cfc <cffunction name="addEditPerson" access="remote" returntype="struct"> a bunch of cfarguments <cfscript> var returnThis = structNew(); var error = ''; structInsert(returnThis,'success',0,true); structInsert(returnThis,'error','',true); structInsert(returnThis,'pers...
Hello, I develop coldFusion applications on my laptop with it's own ColdFusion 8 server with IIS which run on Windows Vista. I am having a rather annoying problem. The problem is whenever I make any changes to my CFC's, it appears that unless I restart my ColdFusion Application server, the changes to my CFC's will not take effect unti...
I've written a database load script in ColdFusion and I'm having a problem that the script slowly runs out of memory. I've split each table load into its own thread with <cfthread> and I'm calling the garbage collector when memory dips below 50% (making sure to have 30 seconds between gc() calls to prevent the garbage collector from hogg...
Is there a way to specify the component path in the tag? I am using ColdFusion Components for my application. My application has several folders, however, and each time I want a CFC to work, I have to save it in the same directory as those files that need access. This results in my creating of several CFC files that are identical. Is ...
Hello, I'm using the following scrip to call a CFC function: function loadQuery() { $.get('QueryData.cfc',{},function(GetMyData){ $("#content").html(GetMyData) }) return false } $(document).ready(function() { $("#loadLink").click(loadQuery) }); This is my HTML: <a href="" id="loadLink">Load It</a> <div ...
I've been doing some logging of object creation times in our open account process in production. Periodically, initializing an object would take way longer than expected. By initializing I mean calling it's init() and passing a couple of arguments that may be simple variables or objects. e.g. <cfset validateObj = createObject("component...
Hello. I have a CFC as singletone object in Application scope. One of the methods is used for massive data processing and periodically causes the "Java heap space" errors. EDIT All variables inside the method are VAR-scoped, so they should not be kept in the object scope when invokation ended. It can be a bit dumb question for Java p...
I'm trying to create pagination for search results using MySQL and ColdFusion. My intention is to only retrieve the queries that can be displayed on a single page, thus making the process efficient. I tried using two queries in my function, but I could not return two variables to the cfinvoke. The following code does not paginate, but ...
I'm calling a Coldfusion component (cfc) using jQuery.post(). I need an integer or string representation of the number returned for use in a URL. {"PAGE":"My Page Title","ID":19382} or {"PAGE":"My Page Title","ID":"19382"} Instead what I get back is a decimal: {"PAGE":"My Page Title","ID":19382.0} Needed to update the following HTM...

Heres the situation. Component B extends component A and overrides the init method to accept a different parameter. A also has a create method that calls init. If i have an instance of B and i call create, its calling the wrong init - it calls init in B, where i need it to call init in A. I dont want to call super.init() as there may n...
