Prepopulate dropdown lists with xml file

[Former Community Member]

Hi everyone,

I'm trying to prepopulate a dropdown list using an xml file. There are many tutorials on the internet that allows me to do that from the preview tab of the designer. However, when I did that it worked well, but i'm not able to "embed" the xml file so that the values will appear in the workspace when the user start a process.

I tried to load the xml file with read resource content in the action profile of the first task, and put the result in the "xmlPrepareData" but the problem is that I can't set any values of the xmlPrepareData after because the xml template isn't exactly the one used by LiveCycle.

Any thought ? Is anyone already succeded in prepopulate a dropdown list with an xml file inside the process ?

Hi,

you make invoke a shortlived process[which populates your dropdown values, example: Query for Multiple Rows as XML service] when the user start a process from workspace and prepopulate a dropdown list using that xml file.

Hi,

First of all, thanks for your response !

I already have an xml file that I use to preview the form in LiveCycle designer.

How exactly do I "prepopulate a dropdown list using that xml file" in a process ?

Thanks

is my understanding correct ..

you want to prepopulate a dropdown list using xml file in XDP/PDF form, when a user initiates a process from workspace..

Yes, you're right.

I have dropdown list which should contain like hundreds of values, so i want those values to be stored in an xml file, simply maintainable.

So I want to add the values in the dropdown list when the users initiates a process from the workspace, exactly

ok gr8 ..

Assuming that u are able to get the xml file from LC process to your XDP/PDF form field.

You can resolve the xml file to dropdown list as -

//clear drop-down list box
*DROPDOWN_Field.clearItems();

choiceList = XMLData.parse(*XML_Field.rawValue, false);

//split the choiceList into an array of values

choices = choiceList.resolveNodes("root.element[*].*NODENAME");

var numchoices = choices.length;

//add an array of values to drop down list
for (var i = 0; i < numchoices; i++)

{
*DROPDOWN_Field.addItem(choices.item(i).value);
}

*DROPDOWN_Field -- Is your drop-down field.

*XML_Field -- Is your XML data that is stored in a TextField.

*NODENAME -- Is node name in your XML to be resolved.

Hope it Hepls..
