Unable to edit template file with 0.9.0

[eximius313]

I have fresh install of eclipse 4.6.2 with only one plugin installed (ScalaIDE from this update site: http://download.scala-ide.org/sdk/lithium/e46/scala211/stable/site)
along with: Play2 support in Scala IDE 0.9.0.v-2_11-201612131054-063b4e8 org.scala-ide.play2.feature.feature.group

When I open any template file the HTML syntax is not colored and if I modify the file - changes are not shown (editor "freezes")

Same exasperating problem !
When entering a simple new line in a view template, everything goes wrong (Cf. logs below)

Clean 4.6.2 eclipse with latest and up-to-date Scala IDE for Eclipse 4.5.0.v-2_11-201612131030-02830a6 and Play2 support in Scala IDE 0.9.0.v-2_11-201612131054-063b4e8.

Hi, I have the same issue with Scala IDE 4.5.0 with all of my Play projects. This has been reported by other users also in Scala IDE: https://groups.google.com/forum/#!searchin/scala-ide-user/template$20editor%7Csort:relevance/scala-ide-user/q9zkW2lA2e4/TgrEsY-pDwAJ

The funny thing is that the "Template Editor" works fine for me, but "New Template Editor" (currently the default) does not work.

[karateboy]

I also have the same issue with 4.5. I thought this is due to the template contains utf-8 Chinese character. This issue has been there for a while. In the mean time, I still stick to IDE 4.4

[wpopielarski]

right now Scala IDE in 4.6.0 is not supporting Play2 because problems with incompatibilities with scala 2.12.1. Just as remainder Scala IDE 4,5.0 supports Play 2.3 and 2.4 which are compliant with scala 2.11.x. Currently we are thinking to support 2.5 and potentially 2.6 but work is not started yet. Sorry for potential inconvenience, 2017-04-25 9:02 GMT+02:00 Aragorn Huang <notifications@github.com>:

[eximius313]

well, since 2.4 is two years old now (May 26 2015) it would be great if you support 2.5 and 2.6
I think we're all eagerly waiting for that

[karateboy]

Thank for the information. I can manually open play template by "Template Editor" without any problem. Does you have any plan to fix it? Or how can I set the default editor back to "Template Editor"?

[lagerspetz]

@wpopielarski I experienced this problem with out of the box http://scala-ide.org/ 4.5.0 with Play 2.5.14. I have not tried with 4.6.0 yet. Other than this, Play 2.5.x works fine.

[wpopielarski]

4.5.0 supports Play 2.3 and 2.4. Actually it is connected with twirl versions accordingly 1.0.4 and 1.1.1. It needs to be upgraded too. 2017-05-02 10:09 GMT+02:00 Eemil Lagerspetz <notifications@github.com>:

@wpopielarski How can I upgrade the editor?

[wpopielarski]

now we are in releasing of 4.6.0 process. We plan RC2 this Thursday and week later if no blocking bugs will be found, final. So I think the prudent and safe estimate for 2.5 and potentially 2.6 will be added around end of May. 2017-05-02 10:45 GMT+02:00 Aragorn Huang <notifications@github.com>:

[eximius313]

Fabulous! Are you testing it also against Eclipse Oxygen (4.7)?

[lagerspetz]

@eximius313 Looks like plugin-profiles will need to be updated with e47 before this is possible...

[lagerspetz]

I'm getting the same issue with "new template editor" with a Play 2.6.0-M5 project using the new 0.10.0 version.
I built it from https://github.com/wpopielarski/scala-ide-play2/tree/0.10.0 using the build args:
mvn -Peclipse-neon -Pscala-ide-dev -Pscala-2.12.x clean verify.
I then installed from the local update site that the build creates on a clean Scala-IDE 4.6.0 release. I also had to modify plugin-profiles to set the scala-version to 2.12.0 for the 2.12.x profile for it to build properly.

[wpopielarski]

I'm working on it. I think the problem is nailed but needs implementation. Hope today there will be some solution. 2017-05-20 16:41 GMT+02:00 Eemil Lagerspetz <notifications@github.com>:
