Re: JQuery .ajax() call posts back to invoking page only on Production
For these sorts of this, I usually will turn on the Developer Tools panel in Chrome and watch the back/forth communication int he browser via the network tab. you can then click on any request's headers, response, etc. -Cameron Hi Cameron, I tried that based on your suggestion and didn't see any indication of back/forth communication. I liked how Chrome groups js and css activities together so I can see where to spend some time cleaning things up. I appreciate your suggestion. Fiddler 2 does a good job for showing the traffic and shows that the ajax requests complete successfully. It's that different behaviour of refreshing the page with querystring params after completing that I'm out to determine the cause. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:350022 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
JQuery .ajax() call posts back to invoking page only on Production
Hello, thank you for any assistance with this puzzler. On my local Windows Vista development machine, I'm using CF 9. Here I have a JavaScript call JQuery's $.ajax() method to write some text to a database using a web service in a CFC. On my machine, it works as expected: writes the values, screen stays put. On production, a leased webserver with Hostek.com, something different happens. The .ajax() call accesses the CFC which writes to the database, then after about five seconds, refreshes the screen with the data passed into the CFC as querystring parameters. This page refresh is mucking up the purpose of using ajax. I haven't a clue why this behavior is server-specific nor if the area of research is Cold Fusion or the CF Admin settings or something else related to JQuery. I have debugging IPs turned off on both environments. Why does an ajax post turn into a get and refresh the URL after it's successful on production and not development? Thanks and hope it's an easy one Brent ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:350011 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Strange form field behavior based on its name
Are out_start and out_end reserved keywords for form fields? I looked for
documentation found no references. When I output their value after submission,
they're get translated to {t '00:00:00'}. If name them out_xstart and
out_xend, the proper date values show. Just an oddity to share.

Re: Empty error message in a query of queries
Thanks for the replies Carl and Brad. Turns out you're both on the right track. The query is the same as it loops over various databases and appends the results using the QofQ. There is no chance of the records being the same since they are in different databases and one of the columns is the database name. The union all seems like a perfect. It worked immediately. I never knew about this option. Thank you, Brad. Carl, there were 45 columns in the query and not having to specify them all was the solution I opted for. Detailing their types may have worked just as well. Thanks again for your help.

Programmatically deleting a datasource
I found some terrific code to access the admin api on House of Fusion here. Thanks to all! In experimenting with the methods, I can successfully create a SQL datasource. What I'm having trouble doing is deleting it. factory.datasourceservice.removeDatasource(theDatasourceName) seems the logically choice. In doing so, the datasource gets deleted from factory.datasourceservice.getNames() but not from factory.datasourceservice.getDatasources(). The datasource will appear in the CF Admin list, but errors if I try to edit or verify it. Something changed, just not everything. Does anyone know what piece I might be missing?

Nestd loop bug with a twist
Hello Forum, I am aware of the bug in regards to an inner loop not being able to access the values in an outer one. It most cases I'd drop a temporary variable right before the inner loop begins so I can reference it inside. What I'm doing now is creating a report from a configuration table that may have additional columns in the future. I run a query from syscolumns to get the list of columns when the report is ran. For the output, is there a way to output a column's value based on the position of the column in the recordset (like an array's index)? The only way I know to output a value is to say #queryName.columnName#. This leads me to cfoutput over the value query, and cfloop over the column query asking for #evaluate(qValues.#qColumns.name#)# where qColumns.name outputs the column's name and the evaluate() outputs the value. The code would work fine if it weren't for CF's nested-loop bug. What happens is the first row's values are repeated for each record which is not the stored data in the database. Any ideas how to either drop a temporary row from the qValues query to reference in the inner loop or access qValues' columns using their ordinal positions? Below is the code: !--- goofs only because of CF bug in nested loops --- table border=1 width=100% tr cfoutput query=qColumnNames td#qColumnNames.name#/td /cfoutput /tr cfoutput query=qValues tr cfloop query=qColumnNames td#evaluate(qValues.#qColumnNames.name#)#/td /cfloop /tr /cfoutput /table Any workarounds appreciated. ~| Upgrade to Adobe ColdFusion MX7 Experience Flex 2 MX7 integration create powerful cross-platform RIAs http:http://ad.doubleclick.net/clk;56760587;14748456;a?http://www.adobe.com/products/coldfusion/flex2/?sdid=LVNU Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:268993 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

A query errors referring to deleted columns yet it doesn't refer to them
Hello All, I'm wondering if anyone else has bumped into this oddity. I had a table with 25 columns that I had an update query update most of the fields. I then took out those fields from the query, and then the database. Happens all the time, right? For some reason, whenever I run the query, it fails stating it cannot find the deleted columns **even though the columns do not appear in the code CF shows with the error**. I've trimmed down the update to be a single column and it still errors stating 'unknown column' for the ones I deleted. If I add the unused columns back in, the query processes so I have a workaround. I was just hoping to only have valid fields in the database and not some that are needed because of a ghost query reference. I recycled the CF service, rebooted, pulled the query out of a cfc and pasted into the file, and still the same error. Any ideas? ~| Upgrade to Adobe ColdFusion MX7 Experience Flex 2 MX7 integration create powerful cross-platform RIAs http:http://ad.doubleclick.net/clk;56760587;14748456;a?http://www.adobe.com/products/coldfusion/flex2/?sdid=LVNU Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:266737 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Re: select * (star) caching
Thank you, Teddy, I will try it out. Thanks for your help and sparing me best practices preaching. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:254480 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: select * (star) caching
Teddy, I was hoping that'd be the answer, but it's not. Doesn't seem to affect
anything relevant to the queries. There must be something because if I add a
column to the table with a star, I got an error value cannot be converted to
the requested type. I changed the query to add a static value ('x' as temp)
and it ran fine. Then I took out the static field, and it ran fine. Thus, I
believe it's something to do with the way CF is caching the query. Does it
matter this query is in a .cfc that is an application-level object with a get
function that runs a star query? I'm thinking it's the star regardless of
CF-implementation.
Any help appreciated.
Brent

Re: select * (star) caching
I don't mind doing so. It would a) save me the headache of going through each query and de-starring it, and b) provide a user-controlled vehicle for flushing this cache so I know when it's going to happen. The initial cost is going to save me tons of mindless coding and testing. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:254506 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: select * (star) cache
Thanks for the comment, Brian. If changing the code recomplies the query, there must be a way to recompile all the queries by marking them for replacement as changing its code does. I'd like to be able to drop all queries from cache with a URL parameter or hidden form field or something I can control. Even a CF Administrator setting or option or process would be fine too. Something short of restarting CF Services or IIS. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:254507 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
Re: select * (star) caching
Thanks for this, Russ! I will test this tomorrow. The checkbox may save a lot of short-term work.

Select * in a view needs recompiled
Using MS SQL Server, I have a view that pulls a table with a *. I added a column to that table, and the view's data did not reflect the new column right away. In Query Analyzer, if I ran the view after adding the column from right-click Open View, the new column wasn't there. If I went into design mode and clicked the !, the new column was there. So in design mode, I added a space and deleted it in the SQL then saved the view. Now I can see the new column from right-click Open View. I'm a bit let down the * isn't as dynamic as it seems. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:250008 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: Select * in a view needs recompiled
I was just thinking that there might be a setting in SQL Server that was geared for optimization and cached the view definition. Perhaps there is a way to reconfigure it to check for changes more often. I might not change it because it's a small extra step to re-save each view (there aren't many) when I change a table that is referenced by a * in that view. It's a question of SQL-processing performance vs development-time performance. Just thinking out loud.

Re: Select * in a view needs recompiled
Thanks for the insights, John. Glad to have my observation on SQL's handling of the * confirmed. ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:250021 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
Path of a cfc important?
Hello all, I have a bunch of .cfcs in the same folder whose init() function creates application-level instances of the cfc object. I make reference to one of these objects as a parameter when initializing another cfc. It works fine when everything is in the same folder. When I pass in an application-level object to a cfc in a different folder, I get an error that the parameter object's type is not the expected type. I'm wondering if anyone has seen this before and knows how to correct. Here's some code to help: /cfcs/email/email.cfc cffunction name=init returntype=email output=false cfargument name=mailserv type=mailserver required=true / cfset variables.mailserv = arguments.mailserv / cfreturn this / /cffunction /cfcs/mailserv/mailserv.cfc cffunction name=init returntype=mailserver output=false ... cfreturn this / /cffunction in application.cfm: cfset application.mailserv = createObject(component, cfcs.mailserv.mailserv).init() / cfset application.email = createObject(component, cfcs.email.email).init(mailserv = application.mailserv) / Thanks in advance. Been trying everything to no avail! ~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:249484 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
