[Tap 4.1.2] More OGNL problems

[Bastian Voigt]

Hi *,

we have the following problem with both OGNL 2.7.0 and OGNL
2.7.1-20070625 on Tap 4.1.2 with a construct like this:

------------html--------------
<div jwcid="@If" condition="ognl: !loggedIn or
!user.hasPermission(@constants.Permissions@FOO)">
    You do not have the permission for this!
</div>
------------java--------------
@InjectStateFlag("loginData")
public abstract boolean getLoggedIn();
   
@InjectState("loginData")
public abstract LoginSession getUser();
-------------------------------

Right after deployment, we are of course not logged in, so !loggedIn
should be true and hasPermission should never be called! and getLoggedIn
does indeed return false if you call it from the Java code!.

However, in OGNL it seems to be false or whatever, because we get an
exception saying "hasPermission" was called on a non-existing object.

1. We tried the following:
<div jwcid="@If" condition="ognl: true or
!user.hasPermission(@constants.Permissions@FOO)">
    You do not have the permission for this!
</div>
-> this works (hasPermission is NOT called, so no exception)

2. We also tried:
<div jwcid="@If" condition="ognl:
!user.hasPermission(@constants.Permissions@FOO) or !loggedIn">
    You do not have the permission for this!
</div>
-> same exception

3. And then we tried:
<div jwcid="@If" condition="ognl: (!loggedIn) or
(!user.hasPermission(@constants.Permissions@FOO))">
    You do not have the permission for this!
</div>
-> same exception


Is this a bug in OGNL, or in Tapestry? How can I find this out?

Oh I forgot to say that all this was working with Tap 4.1.1

Did you try to replace getLoggedIn() by isLoggedIn()?

Not sure, can you file in http://jira.opensymphony.com/browse/OGNL just in
case?  I usually do them all in one batch so it's in everyones best interest
to get them in to jira asap.
