Re: WOIFrame Question
Hi Mike,
we use JavaScript to do this.
Put a function in the page containing the iframe that will set the
height of the frame:
script language=JavaScript
function setFrameHeight(height) {
document.getElementById('theframe').height = height;
}
/script
and then call this function from the page that is loaded into the frame:
script language=JavaScript
try {
parent.setFrameHeight(550);
}
catch(e) {}
/script
But JavaScript will only do this if the two pages come from the same
server (same domain name)

Hi, I'm trying to create a WOIFrame which changes it's frame height
dynamically, depending on the height of the page it displays. For
example, if the inner page contains no data, I'd like the WOIFrame to
have a height of 0 pixels. If the inner page contains a few entries,
I'd like it to expand to say... 100 pixels. If the inner page
contains a large amount of data, I'd like it to expand to a maximum
length of 400 pixels, and also display a scrollbar. Are there any
easy ways to do this?
Thanks,

Re: Newbie JavaScript Question
Hi Mike,There are a number of things you can do. You can include the script in the head section of the page where you want to call it. You can include it in a page template. You can include your script as a WebServer resource and bind it to WOJavaScript (you can find this on the palette in WOBuilder). http://developer.apple.com/documentation/WebObjects/Reference/DynamicElements/WOJavaScript/chapter_21_section_1.htmlI do the latter in my page templates so that I can call this particular script from any input form:headWEBOBJECT NAME=CalendarPopupJavaScript/WEBOBJECT/headCalendarPopupJavaScript: WOJavaScript { scriptSource = "calendar.js"; hideInComment = true;}One thing that you must look out for if you are deploying using XCode is that under the WebServer resources target, ".js" files end up in the Compile Sources folder. They must be manually moved to the Copy Bundle Resources folder.DavidOn 26 Jul 2006, at 9:45 AM, Chip Myers wrote:Hi, I'm trying to incorporate some _javascript_ into my webobjects file.

Direct to Web Services Caching Problem
Hi all, Recently I created a Direct to Web Service application, and used WebServiceAssistant to add services and operations. There is absolutely no coding and it works great until the following problem occurred: Even though I added -WOCachingEnabled NO for the web service instance, it still somehow caches the old data. Only when the web service instance is restarted, it will re-fetch and get the latest information. I wonder where the data is cached and how to prevent such caching? Do I need to write my own code to handle it? Any settings or application properties to include? This is my first web service application. Please help me if you know how to solve it. Thanks a lot.

Re: EOObjectNotAvailableException
EOF looks at it a different way, and I can understand their approach. If you had a foreign key to the other table in your table, and it was NULL, then it's ok if the relationship is not mandatory. In their eyes, since you happen to use the same primary key for both objects, it figures it MUST be there, because the key has a value.There are ways to use delegation (can't remember which delegate) to catch the fault firing, and if you don't find the object, return null instead of a blank one. I've done that before...KenOn Jul 25, 2006, at 11:20 AM, Watkins, Garry wrote: Really not the answer that I wanted. Personally, I think that it is a bug in EO, if the relationship is defined as NOT mandatory, and it encounters a EOObjectNotAvailableException it should return null. However, I want to continue to use EOGenericRecords since it is mainly a reporting type application. Does anyone know where the Fault is triggered inside the EO stack so that I might be able to trap the operation with AspectJ? This would also require that I have the EORelationship that triggered the fault.

Re: JDBCChannel method failed to update
Hi, Thanks to everyone who replied. I have removed locking from all but the primary key from the entity and this has remedied the problem. But I am concerned that this is not correct and may cause other problems. It is not possible for the this error to be handled by the user because it occurs within a web service operation that does not provide persistent transactions. The problem appears when the user is making a series of modifications to one entity and I think it is due to that each transaction/ modification is being handled by a different instance of the application whose object store has become dirty. So in addition to reducing the locking attributes I have ensured that the EOEditingContext refaults before each transaction. (I suspect only one would be necessary.) Cheers, Corin.

Catching this exception, then getting the user to handle the modification somehow is probably the solution you should consider rather than unchecking attributes used for locking.

Direct Action vs. Component Action...
Hi, The first part of David LeBer's articles on Direct Actions (http:// david.codeferous.com/?p=63) says the following about component actions: each visitor will receive a relatively heavyweight Session object, so they may not be appropriate if you expect a lot of visitors and/or you do not need to track their state. Direct Action are designed for these situtations. So if I have a direct action which (1) requires a session object, and (2) returns a WOComponent object, will it be as heavy weight as a component action? If not, what is it that makes component actions relatively heavyweight? If I have a site where multiple things can be accessed via direct actions, and if I want some of these things to be available only to registered users, would I need a session object for these direct actions?
