Description

The following throws a NPE in OGNL 2.7 but not in previous versions:

test.html:

<span jwcid="@Insert" value="ognl:(text1 == null) ? 'Empty' : text1.length()"/><br/>

<span jwcid="@Insert" value="ognl:(text2 == null) ? 'Empty' : text2.length()"/> <------- text2 is null

test.page:

<page-specification>

<property name="text1" initial-value="'text1'"/>

<property name="text2"/> <------- text2 is null

</page-specification>

exception:

java.lang.NullPointerException: target is null for method length

at ognl.OgnlRuntime.callMethod(OgnlRuntime.java:963)

at ognl.ASTMethod.getValueBody(ASTMethod.java:90)

etc.

Another thing I noticed is that:

<span jwcid="@Insert" value="ognl:(text1 == null) ? '1' : text1.length()"/><br/>

works for the previous OGNL, but not for 2.7
