Seifeddine Dridi updated FOP-2317:
----------------------------------
Description:
<fo:table-cell width="" border-left="0.5pt green dashed">
<fo:block>Cell</fo:block>
</fo:table-cell>
FOP issues a warning because border-left has an invalid structure (the
border-style should be placed before the border-color).
In FObj.warnOnUnknownProperties(), there is a call to
getAttributeNameForValue() to find the name of the attribute whose value is
unknown, then it stumbles on the width="" property, which returns a null object
when instantiated. And there goes a NPE which leads to a crash:
if (prop.equals(value)) {
return attributeName;
}
I attached a patch which encloses the above code with a simple if-test.
