Interactive tree error

[Søren Tolstrup]

In 1.5.3 the Interactive Tree view isn't working with some individuals. The error message is:

Catchable fatal error: Argument 1 passed to TreeView::drawPerson() must be an instance of WT_Individual, null given, called in /usr/local/www/[username]/www/webtrees/modules_v3/tree/class_treeview.php on line 292 and defined in /usr/local/www/[username]/www/webtrees/modules_v3/tree/class_treeview.php on line 212

The tree is working fine with other individuals. I haven't figured out a pattern.

In my case it is only for myself that this problem occurs. Maybe it's because I am set as the Default person?

[Ulf Granlund (ulf-granlund)]

What I wrote above was not correct. I have now found one more individual that is affected by this error. And setting another individual as the default person did not change anything, so it has nothing to do with that.

Could it be related to one-parent families?

[fisharebest (fisharebest)]

Yes. It happens when the partner of the person has a mother, but no father.

[Ulf Granlund (ulf-granlund)]

In my tree it is not related to one-parent families. I have at least two individuals in my tree where the problem occurs and their partners both have two parents.

[fisharebest (fisharebest)]

Looking at the code, the problem occurs when the partner of the person has a mother but not father.

(Father but no mother is OK).

[Grzegorz (g.m.)]

This affects newer generations as well.

[fisharebest (fisharebest)]

Can you provide me with a GEDCOM file that will demonstrate the problem?

(1.5.3)

[Ulf Granlund (ulf-granlund)]

Similar case in my tree. Father and mother exist for both the individual and partner:

Is this enough or do you need the actual GEDCOM?

[Ulf Granlund (ulf-granlund)]

However, there is a grandfather missing. It seems the problem climbs upwards in the tree. But not always and to all generations. The problem "jumps" some generations.

[fisharebest (fisharebest)]

I would need a GEDCOM file that demonstrates the problem.

[Ulf Granlund (ulf-granlund)]

Have sent it to you by email.

[fisharebest (fisharebest)]

Thanks for the file.

In webtrees 1.5.3, I see the error. In the fixed version (2014-05-06), I do not see the error.

> In my tree it is not related to one-parent families

Checking the data, I see that F146 has a mother but no father.
This family is included in the chart.

[Ulf Granlund (ulf-granlund)]

I was not aware of a fix.

When you wrote that it was related to one-parent families, I would interpret that as meaning
that the individual would have to be a member of a one-parent family in order to experience the error.
This was/is not case. Apparently it is enough that there is a one-parent family somewhere down the tree
for the error to occur. That is something quite different. But if your fix fixes the latter case also, then
I guess it's fine. I would like to download the fix. Is it available somewhere?

[fisharebest (fisharebest)]

> Is it available somewhere?

Yes. See the forums...

[Ulf Granlund (ulf-granlund)]

OK. Thanks. The replacement file seems to have solved the problem.

[fisharebest (fisharebest)]

The fix is not released (in a stable version).

The status will be changed to "released" after the 1.5.4 version is released.

[fisharebest (fisharebest)]

Fix released in 1.6.0
