Hi,

I'm developing a target platform base on eclipse 4.11, I included RED v0.8.11 using target file and used maven to build a product. I always get error when open a robot file source tab. I can not do every thing because this issue. Could you take a look on it ?

Thanks,
Nghia

Hi,

I'm unable to reproduce your issue. How is your target platform configured? What features does it include?

Are you aware of any plugins which somehow would contribute to action bar? In the definition of editor:

RED/src/Eclipse-IDE/org.robotframework.ide.eclipse.main.plugin/plugin.xml

Line 341 in aa36f05

contributorClass="org.robotframework.ide.eclipse.main.plugin.tableeditor.RobotFormEditorActionBarContributor"
we add action bars contributor which itself is defined here: https://github.com/nokia/RED/blob/master/src/Eclipse-IDE/org.robotframework.ide.eclipse.main.plugin/src/org/robotframework/ide/eclipse/main/plugin/tableeditor/RobotFormEditorActionBarContributor.java

As you can see in the source this contributor adds StatusLineContributionItem under ITextEditorActionConstants.STATUS_CATEGORY_INPUT_POSITION category.

Then SuiteSourceEditor attaches a listener on a caret position and here:

RED/src/Eclipse-IDE/org.robotframework.ide.eclipse.main.plugin/src/org/robotframework/ide/eclipse/main/plugin/tableeditor/source/SuiteSourceEditor.java

Line 207 in aa36f05

final StatusLineContributionItem find = (StatusLineContributionItem) getEditorSite().getActionBars()
it looks for the item in order to update position. It expects to be of type StatusLineContributionItem since the contributor registered this item under the same category.

Overall this mechanism is responsible for displaying and updating the element marked with red on screenshot:
source_position

Do you have other plugins possibly somehow altering the items contributed to status line when Robot editor is open?

Closing due to no answers from reporter + no one else run into this issue. RED 0.9.0 is based on eclipse 4.13 instead of 4.9, so maybe this is also fixed (if this was RED issue)

Sorry for my late response. We imported RED source codes to my project and added workaround for RED v0.8.11. Now We upgrade the Eclipse and upgrade RED and get error again, we could have to add source codes again. We hope that you can fix it in next release to avoid our effort. I'm very appreciate your help.
