When generating the report as HTML (with servlet=frameset), the JavaScript of a text field gets evaluated besides the fact, that the visibility should prevent showing the text field. This results in a NPE when calling model.getEvaluator().getGender(), which the Visibility condition should prevent. It works as expected with DOC and PDF. It seems that the JavaScript gets otherwise processed than with servlet=run. <text id="833"> <property name="fontFamily">"Arial"</property> <property name="fontSize">7pt</property> <property name="paddingBottom">10pt</property> <list-property name="visibility"> <structure> <property name="format">all</property> <expression name="valueExpr" type="javascript">model.getEvaluator()==null</expression> </structure> </list-property> <property name="contentType">html</property> <text-property name="content"><![CDATA[Bearbeitet von <VALUE-OF>model.getGenderTitle(model.getEvaluator().getGender())</VALUE-OF> &nbsp;<VALUE-OF>model.getEvaluator().getLastName()</VALUE-OF> &nbsp;<VALUE-OF> <BR />]]></text-property> </text>
We have to evaluate the value script even when visibility is false because firstly visibility is processed after value is evaluated; secondly, the visibility may be false for some formats and true for others. So please don't assume the value script won't be executed if item is hidden.
Thank you for the quick answer. > We have to evaluate the value script even when visibility is false because > firstly visibility is processed after value is evaluated; Why is that? I mean this makes the visibility check useless. I still have to evaluate inside the text element, whether the property is null and exclude it from output. Maybe there are elements in the documents tree for which this behaviour might make sense, but for elements of type TEXT??? > secondly, the visibility may be false for some formats and true for others. The JavaScript code (for example: model.isElementXyVisible() ) can have different results on different output formats? > So please don't assume the value script won't be executed if item is hidden. This should be documented in detail. In PDF format, the JavaScript doesn't get executed when visibility == false. So I have no reason to expect a different behaviour for HTML output.
