Binding Exception for generated property in Foreach
Hi-
Sorry to spam with questions today, but I'm stuck on something that
should be straight-forward.
I keep getting a binding exception for my index property in the Foreach
loop below - it looks like it thinks the property is read only (which
it shouldn't be, despite the name). There is no abstract methods for
these properties in the page, they are completely synthetic. I should
mention that I am not positive on this syntax in the html:
<span jwcid="@Insert" value="ognl:readOnlyFieldNames[readOnlyIndex]" />
but it doesn't seem to be causing the error. The intention of that
line is to use readOnlyIndex as an index into the string array
readOnlyFieldNames.
