Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Re: List Control - action javascript - how to define session variables

    Thanks again David, understood, you're right it is embedded and Orders2 is the alias. I got it working and discovered some things...

    1. I had to move the hidden "cid" control out of the panel that contained the list.
    2. I was using Action javascript with "inline javascript" to run your code then "panel actions" to open the panel. Changed this to all text javascript like the demo you sent.

    After testing it seems both these things prevent the "cid" field from populating.

    So it works, huge thanks...but there is a lag when you go back and forth choosing items in the list testing on an iPhone, preview is faster so not noticeable.

    When the embedded UX is displayed the previous choice is visible while it updates, is there a way to shorten the lag or clear the embedded UX before it displays, maybe a time delay? (I'm running local sql on windows 7)

      Jim,

      Your item # 1 has me wondering... do you have a panelcard around your List control... in the UX which is embedded? The hidden control belongs to the child UX. And, unless you have a reason for using a panelcard here, you don't need one. The panelcards only need to be used in the parent UX.

      Item # 2 makes sense (that it wouldn't work) because this.value is no longer valid for the List control. Instead, you need to use .getValue to get the value of the List control.

      I don't see the previous choices... the lag... they may be there but it's updating so fast I can't really tell.

      Running the code directly is definitely a bit faster than going through Actions.

      And I would probably go with the "filter" method instead of a hidden field... it's cleaner.

      Here's an example of using Action Javascript compared with using javacsript directly.

        Great video David, thanks again... I stripped down the ux I'm embedding, took out all the panel cards and now it's just the list control, using the filter method.

        I have Alpha on a Virtual Box VM running on a Mac, I publish the app, view it in safari on the mac and it runs fast, on the iPhone over the wifi it lags, when I let the app sit for a while the lag is very long. Question: I guess it could be my wifi but if the app is running on say Zebra Host and the user has a slow connection will these lags be apparent? I thought a lot of the data was cached in the device browser...
