[Xerte] Re: Xerte 2 : Combo box value is defaulting to "" why?

[Julian Tenney]

Can do that, yes, if it doesn't already work? I know some controls take default values, precisely because when an optional attribute is added, it adds a null value: did you try what I suggested? This code from the wizard suggest all optional properties will handle a default value.

//add optional properties
addPropListener = new Object();
addPropListener.click = function(obj){

       if (wizard.nfoObject.wizard[tree.selectedNode.nodeName][optProps.selectedItem.data].defaultValue != undefined){
              tree.selectedNode.attributes[optProps.selectedItem.data] = wizard.nfoObject.wizard[tree.selectedNode.nodeName][optProps.selectedItem.data].defaultValue;
       } else {
              tree.selectedNode.attributes[optProps.selectedItem.data] = ""
       }
       tree.dispatchEvent({target:tree, type: "change"});
}
addProp.addEventListener('click', addPropListener);

Thanks for your help.

It seems strange to me that a combo box / drop down menu should default to returning "" rather than the value of the first element in the list.

Since the xwd file provides the data for the construction of the wizard, I guess the behaviour of the wizard is governed by the code that processes the xwd file and presents the wizard form to the user, and that this is a part of the core Xerte code. Would it be possible to update the code so that a combo box when run could have either a default value specified in the xwd file or alternatively that it just defaulted to returning the value of the first item in the list unless one of the other items had been selected?

Kind regards

Johnathan

Hello Xerte team,

As far as I can tell this line is set up like many other optional property lines and I don't recall hitting this problem before

In an xwd file I have the optional property

<narPlayback type="ComboBox" label="Narration Playback" options="On page load,On user request" data="pageLoad,userRequest" default="pageLoad" width="150" optional="true"/>
When the page wizard is opened and the Narration Playback property added and the page wizard closed, the value of narPlayback changes from undefined to ""
If the page wizard is re-opened the combo box displays the selected value as "On page load".
Clicking on the value "On page load" does not change the value from "" to "pageLoad".

The only way I can actually set the value of narPlayback to "pageLoad" is to select the alternative option from the combo box i.e. "On user request" and then to select "On page load"

What am I missing here?
What do I need to do to ensure that when the optional property is added it receives the default value of "pageLoad"?

Kind regards

Johnathan
