Relations not rendered right away

[bastiK]

Create a new Layer and create a new multipolygon relation (with area tags on the relation only.)

-> It is not rendered as an area.

Do some stuff like save and reopen or duplicate layer or just add a single tag. -> It is rendered as an area.

[bastiK]

create a relation like this. Note that the bug is not visible if you just open the file.

[jttt]

I can't reproduce this (tested with sun java)

[bastiK]

It's quite easy to miss this, if you do not follow the exact steps.

Another way to see it: Open the file and make a duplicate of the relation. Then delete the old relation. Then the multipolygon is not rendered. If you move a node it is ok.

[jttt]

It works for me. Is the multipolygon correctly rendered after you add any point to the dataset or do you have to do some modification on the multipolygon itself?

[bastiK]

No effect:

• add a node
• add a node to a way of the multipolygon
• move that node around

rendering starts correctly:

• move a node that was there in the first place
• add an arbitrary tag to the relation

once it is rendered correctly there is no way to expose the bug again

Replying to jttt:

#4696 includes a small test case and "test script" which reliably reproduces the defect.

[jttt]

Now it looks clear, bbox for relations is cached and it's not updated when node is added to the relation. I'll fix it when I get home.
