CONNECTIONTYPE UNION & STYLEITEM "AUTO" problem with beta7 and rc1

[jmckenna]

Initially reported by Christy:

* ...However, if I have styling in the source layers (i.e. layer_1_for_union and layer_2_for_union) and use STYLEITEM "AUTO" in the union layer, the two source layers must have STATUS DEFAULT for anything to show up (which, I think, causes them to be drawn twice?). *

I've also tested and I confirm that there is a problem with beta7 and rc1 when using STYLEITEM "AUTO" on the union layer. I am attaching my example from the docs that works with beta6.

Committed a fix in r11639

• trunk now works with the doc example for me (union with styleitem auto)

[tamas]

applied a fix for an issue in r11664, thanks to Jana Golinowski

Can we mark this one fixed now? Or is there another pending issue?

[cnieman]

I'm currently recompiling to check.

[cnieman]

Works for me as long as there is only one class in the source layers. Should it work with more than 1 class?

Replying to cnieman:

I hope so. Did you have an issue with this?

[cnieman]

It seems that as long as I only have one class per source layer, and that the class doesn't have an EXPRESSION, it works. Once I add an EXPRESSION, the layer no longer draws.

I tried with two classes and no expression, and it draws as expected, using the styling from the first class.

I can't reproduce this on Windows with trunk. On unix I get Christy's problem, and the ms_errorfile contains:

  [Mon May  9 20:40:47 2011].326101 msEvalExpression(): General error message. Can
      not evaluate expression, no item index defined.
  [Mon May  9 20:40:47 2011].326124 msEvalExpression(): General error message. Can
      not evaluate expression, no item index defined.
  ...

Just applied a fix for the expression problems in r11665. Any testing would be appreciated.

Just recompiled with r11665 and still seeing the same behaviour with the same errors Jeff posted in his last reply.

Do you have a working example to reproduce this?

[cnieman]

Example of STYLEITEM AUTO still not working with expressions for me on Linux

[jmckenna]

Also note that the errors that I reported earlier ("Cannot evaluate expression, no item index defined.") exist on Windows in the ms_errorfile as well, but the features are drawn correctly.

[tamas]

Fixed the problem in r11667. Tests are welcomed

[tamas]

Further fixes in r11668 and r11669

[cnieman]

Just recompiled and it looks good now!

[jmckenna]

also tested on windows and unix: works on both, and those 'no item index defined' errors are gone.
