[udig-devel] Problem with custom SLD style

[Lukasz Stawicki <stl@xxxxxxxxxx>]

I have a customized SLD style files for my layers on the map. I were  
working perfectly with uDig 1.1 / GeoTools 2.2.* release.

But it crashed with GeoTools 2.6.4 (or is it 2.6-SNAPSHOT - no  
difference with 2.6.4 as I see).

<sld:LineSymbolizer>
                        <sld:Stroke>
                            <sld:CssParameter name="stroke">
                                <ogc:Function name="if_then_else">
									<ogc:Function name="lessThan">
										<ogc:PropertyName>VOLTAGE_ID</ogc:PropertyName>
										<ogc:Literal>3</ogc:Literal>
									</ogc:Function>
									<ogc:Literal>#FFBB55</ogc:Literal>
									<ogc:Function name="if_then_else">
										<ogc:Function name="lessThan">
											<ogc:PropertyName>VOLTAGE_ID</ogc:PropertyName>
											<ogc:Literal>7</ogc:Literal>
										</ogc:Function>
										<ogc:Literal>#F78484</ogc:Literal>
										<ogc:Literal>#5C993C</ogc:Literal>
									</ogc:Function>
								</ogc:Function>
......

and it crashes
