Experimental Physics and Industrial Control System

Hi,

I debugged the source code. The problem is in following class

org.csstudio.opibuilder.properties.StringListProperty:

public Object checkValue(Object value) {
if(value == null)
return null;
List<String> acceptableValue = null;
if(value instanceof List){
if(((List<?>) value).size() == 0 ||
(((List<?>) value).size() > 0 && ((List<?>) value).get(0) instanceof String))
acceptableValue = (List<String>)value;
}
return acceptableValue;
}


So unless the value is a java.util.List, the property will not be set. There needs to be a conversion step somewhere which either converts a String to a java.util.List or org.mozilla.javascript.NativeArray to a java.util.List.

Cheers,

Xinyu

Hi Xinyu,
I am experiencing the same problem with CSS 3.1.4.

In theory, display.getWidget("BitFileComboBox").setPropertyValue("items",  "[choice1, choice2, choice3]"); should work.
Since when I getPropertyValue of the manually set widget I get [1, 2, 3].

Strange, indeed.

Hi,

I have a combo box, and I would like to set its items (ie the available options) dynamically using a javascript.

I tried the following and it did not work.

display.getWidget("BitFileComboBox").setPropertyValue("items",  "[choice1, choice2, choice3]");

I also tried array object and it did not work either:

var mycars = new Array();
mycars[0] = "choice1";
mycars[1] = "choice2";
mycars[2] = "choice3";
display.getWidget("BitFileComboBox").setPropertyValue("items", mycars);

Thanks,
