I'm passing GML features to a Vector layer. I need to put the feature name in
a label. Some of my features have numeric names, for which the leading zeros
are significant. My problem: the leading zeros are being stripped.
I've tracked this down to OpenLayers.Style.createLiteral(), which checks to see
if the replacement value is numeric and does a parseFloat() if it is.
OpenLayers.Style.createLiteral = function(value, context, feature) {
if (typeof value == "string" && value.indexOf("${") != -1) {
value = OpenLayers.String.format(value, context, [feature]);
value = (isNaN(value) || !value) ? value : parseFloat(value);
}
return value;
};
I'm not sure why this is being done. It's not like style labels should ever be
processed as if they are numeric. They seem to me to be descriptive by
definition. Perhaps this same function is being used elsewhere where the
numeric conversion is necessary. Still, it leaves me with a problem.
What is the cleanest way to prevent this? It doesn't happen if I add printable
characters to the label field: "name: ${name}" works fine. Unfortunately, I
need an unadorned name, without extra characters. I've tried adding spaces,
and I've tried adding , and neither worked.
Ideas?
