Designer ES2 Scripting Reference

This is one of the references I find the most useful when writing scripts and it’s now available for Designer ES2.

What’s more, you can now find all of the ES2 Developer and Programmer documentation all in a single place just like all ES2 documentation (which includes the Dev and Prog docs from the former link). Great sites to bookmark and nice to finally have it all in one spot!

This all comes to you due to the recent LiveCycle Developer Center site refresh in conjunction with the recent release of LiveCycle ES2. Check it out!

Multi-Selection List Schema Definition

After spending some time, recently, showing you how to connect your form to a schema and highlighting Designer’s support for schema metadata, I thought I would round-off my current train of thought on schemas by tackling multi-selection listboxes. Since they store their selected data in <value> nodes, once you think about it, their schema definition may not be obvious. When you’re working with XML data that isn’t governed by a schema and namespaces, it is perhaps easier to work with (i.e. accept) these <value> nodes however things change when you have a schema telling you how your data must be structured and scoped (with namespaces).

Schema Metadata

My first tutorial on XML schemas explained how to connect your form to a schema however it did not show some of the Data View palette’s special features with respect to metadata in XML schemas.

Using metadata based on a combination of the XML Schema appInfo and Dublin Core title and description elements, you can influence how the Data Connection Wizard creates fields you drag and drop from the data connection tree into your form. You can also direct the Data View palette to show some of this information in the Schema Data Connection Tree that it displays.

Tip: Pretty XML Strings

I regularly use the saveXML() method, available on all node class-based objects, as a way to debug my forms (think of it as a type of introspection technique). The method outputs a string representation of the XML content of the node in question, which helps when attempting to discover the underlying object structure without a debugger…

For example, say you have a simple form with a text field and a numeric field. The following statement will output the form’s data to the JavaScript Console in Acrobat:

console.println(xfa.datasets.data.saveXML());

The result, however, isn’t very readable:

<?xml version="1.0" encoding="UTF-8"?>
<xfa:data xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/"
><form1
><TextField1
>asdf</TextField1
><NumericField1
>1234</NumericField1
></form1
></xfa:data
>

Though I had been using saveXML() for quite some time, I hadn’t realized that it actually takes an optional parameter, a string with a value of “pretty”, that results in much nicer output.

console.println(xfa.datasets.data.saveXML('pretty'));

results in the following pretty/readable output:

<?xml version="1.0" encoding="UTF-8"?>
<xfa:data xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
   <form1>
      <TextField1>asdf</TextField1>
      <NumericField1>1234</NumericField1>
   </form1>
</xfa:data>

LC Designer ES2 Action Builder First Peek

Steve, on the LC Designer Team, has posted a good introduction to LC Designer ES2‘s Action Builder feature. This feature is going to be very useful, especially if you’re not comfortable with writing scripts and need to get some basic but powerful logic to function properly. Actions will take care of it all for you so that you don’t have to write a line of code!

Check-out more posts on Actions and the Action Builder feature:
