Jasper compiler error when using SUM method
问题 I'm using the Jasper built-in SUM function in a cell of a table. It should sum the content of other cells (in the example I'm using a single cell, but the output is pretty much the same adding multiple cells). The jrxml is: <jr:column width="49" uuid="e6595bc8-b46e-4bbe-85a2-7ea9526fce83"> <property name="local_mesure_unitwidth" value="pixel"/> <jr:columnHeader style="Table 2_CH" height="20"> <staticText> <reportElement x="2" y="0" width="47" height="20" uuid="af5e8305-5cdf-41ad-b827
