We are in the process of upgrading from Tapestry 4.0.2 to Tapestry 4.1.5.
I've run into several porting issues along the way, but the most problematic
is:
ERROR HiveMindExpressionCompiler - Error generating OGNL getter for
expression
We use some OGNL expressions in our application that are probably more
complex than is typical. It seems that 4.0.2 with OGNL 2.6.9 allowed these
more complex OGNL expressions, but _apparently_ OGNL 2.7.2 has regressed in
this regard.
Here are some examples of the OGNL expressions we have in our application
that are causing problems with the latest Tapestry, OGNL libraries:
<binding name="queryParameters"
value="ognl:[EMAIL PROTECTED]@class,
@[EMAIL PROTECTED]()
.addEqFilter('photoType',@[EMAIL PROTECTED])
.addScopeFilter(getUserScope())
.addConCategoryFilter(components.categoryRetriever_UserPhoto.pageCategory)
.setSortBy('publishDate desc') }" />
<binding name="sortingCriteria"
value="ognl:{ #{'label':'Latest', 'criterion':'publishDate
desc','default':true},
#{'label':'Title', 'criterion':'title asc','default':false},
#{'label':'Most Popular', 'criterion':'counter.viewCounts.total
desc','default':false},
#{'label':'Most Commented',
'criterion':'counter.commentCounts.total
desc','default':false},
#{'label':'Highest Rated',
'criterion':'counter.ratingSummary.ratingAvgScore desc','default':false}
}"/>
So, these expressions succeed in Tapestry 4.0.2 + OGNL 2.6.9, but fail with
Tapestry 4.1.5 + OGNL 2.7.2. Is this a known issue?
Here is an abbreviated stack trace:
ERROR HiveMindExpressionCompiler - Error generating OGNL getter for
expression { @[EMAIL PROTECTED],
@[EMAIL PROTECTED]().addEqFilter("galleryType",
@[EMAIL
PROTECTED]).addScopeFilter(getEditorScope()).addConCategoryFilter(components.categoryRetriever_EditorPhotoGallery.pageCategory).setSortBy("publishDate
desc") } with root [EMAIL PROTECTED] and body:
