New Web Service Sample Form Posted

0

It was recently brought to my attention that the web service used by my sample form for my tutorial on connecting a form to a web service is no longer operational. Obviously, that makes the sample form much less useful so I have posted a second sample form that uses a different web service. If you have been struggling with the original sample, please have a look at the new one I posted in an update to the original post.

Show the List of a Drop Down List

2

Did you know that the list portion of a drop down list field can be displayed programmatically? You can set focus to the field and force its drop list to be displayed all in a single API call:

xfa.host.openList(@object)
xfa.host.openList(@string) -- deprecated since XFA 2.6

where @object is a reference to the drop down list field and @string is the SOM expression of the drop down list field.

xfa.host.openList(myDropDownList); // set focus/show the drop list

The second form of the API has been deprecated since XFA 2.6 which means that since Designer 8.1, it is preferred to use the first form which takes a reference to the field rather than its SOM expression.

If you’re using Designer 8.0 or earlier, you can get the SOM expression of any field by using its somExpression property:

xfa.host.openList(ddlInDesigner71.somExpression)

This works in both JavaScript and FormCalc with the same syntax.

Now if only there was a way to programmatically show the drop calendar of a date/time field…

Acrobat JavaScript Debugger on XFA Forms

0

Many of you have been requesting some debugging features for XFA Forms (and I’m sure many more of you just haven’t voted for it yet). It so happens that Acrobat Pro has a JavaScript Debugger which can be used — to a limited extent — with XFA Forms. See John Brinkman’s post to learn more about it — thanks John!

As he puts it, there are limitations, the biggest ones of them being, in my opinion, the inability to debug script objects and the inability to retain breakpoints between debugging sessions. Nonetheless, this tool can give you way more insight than the good old “JavaScript Console + saveXML(‘pretty’)” combination can in certain cases, and it does it in a nice tree to boot!

Tech Talk on Database Connected Forms

2

Paul Guerette, a colleague of mine at Adobe, will be giving a “tech talk” eSeminar on connecting forms to databases over at AcrobatUsers.com on Tuesday, March 23, 2010, at 10am PST (1pm EST).

If you have been struggling with connecting a form to a database, are wanting to know what the best practices and/or security concerns are, or have some specific questions you would like to ask, I highly recommend you attend the session. It’s free to attend (and free to become a member in order to attend)!

I’ll be answering chat questions “live” as the session unfolds. I hope you can join us!
