Hello group!
I created a GetFeatureInfo-template for a 2-band raster layer. This works
fine and i can get the band values and convert them into numbers and write
the into a table:
<td>${cell.attributes["dgm"].value?number}</td>
<td>${cell.attributes["wd"].value?number}</td>
Now i want to add these two values, this is the part that does not work.
this creates a text output like n1 + n2 (n1,2 are the correct numbers)
${cell.attributes["dgm"].value?number} +
${cell.attributes["wd"].value?number}
This does not work:
${${cell.attributes["dgm"].value?number} +
${cell.attributes["wd"].value?number}}
Writing a function sum does also not work with the expressions only with
fixed numbers like 10or 20:
<#function sum a b>
<#return a + b>
</#function>
...
<td>${sum(${cell.attributes["dgm"].value?number},${cell.attributes["wd"].value?number})}</td>
Changing the localization does not have an effect:
<#setting locale="de_DE">
Can someone give me a hint how to add two expressions with freemarker?
Thank you in advance
Uwe
