Error When Executing PlantUML Macro 2.0

[GOhrner]

Xwiki 12.10.8

What did I do wrong, and how to fix it?

I just upgraded to PlantUML Macro 2.0 by first uninstalling Macro 1.1 and then installing Macro version 2.0.

Now my PlantUML sections just fail:

Failed to execute the [groovy] macro. Cause: [No signature of method: java.lang.String.setObjects() is applicable for argument types: (com.xpn.xwiki.api.Document, com.xpn.xwiki.api.Context, String) values: [Example Com.Technik & EDV.Server- und Internet-Dienst-Infrastruktur.WebHome, ...]]. Click on this message for details.

Clicking this message shows the macro code and a stack trace - not sure if it makes sense to show it here, but just in case:

The pasted error suggests that the old version is actually still in use for some reason. Are you sure you uninstalled it ? If yes were all the pages listed for deletion selected ? Does the page XWiki/PlantUMLMacro page still exist (that’s where the 1.x macro used to be stored) ?

@tmortagne

Positive:

@tmortagne

If yes were all the pages listed for deletion selected ? Does the page XWiki/PlantUMLMacro page still exist (that’s where the 1.x macro used to be stored) ?

No, does not look like:

So nothing with the name “PlantUMLMacro” which I could find, just pages called “PlantUML” (without suffix “Macro”). The actual toplevel node also doesn’t seem to exist as a page, the subordinate spaces/pages do:

[tmortagne]

Did you try to access the page with reference XWiki.PlantUMLMacro ? The URL should be something like https://myhost/xwiki/bin/view/XWiki/PlantUMLMacro.

If this old page really does not exist, then maybe the wiki macro was not properly unregistered for some reason, in which case a restart should fix it.

[GOhrner]

Ok, when I tried to access the page directly, I used the wrong URL.

Apparently the page actually is still there:

Why wasn’t it deleted when removing the PlantUML Macro extension? Can I now just delete it manually?

[tmortagne]

@GOhrner

Why wasn’t it deleted when removing the PlantUML Macro extension?

Hard to say now, when an extension is uninstalled all the pages that were part of it are listed for confirmation and if a page is different from the standard version (customized) it’s unselected for delete by default, so maybe that was your case.

@GOhrner

Can I now just delete it manually?

Yes.

[vmassol]

Also note that 2.0.1 is now released, see PlantUML Macro 2.0.1 released

[vmassol]

@GOhrner let me know how it goes, I didn’t know we had some users of this macro so I’m curious to see how the new version works for you! It should normally perform better (faster, async, etc).

Thx

[GOhrner]

@tmortagne , @vmassol : Ok, after manually deleting the old Macro page (well possible that for whatever reason it was unchecked during deinstallation and I missed that) and upgrading the PlantUML plugin to 2.0.1 it now works.

An additional mistake I made was not to reconfigure the server to “empty” immediately in the config screen, which caused the Macro to use the public PlantUML server at first. Fortunately, I don’t have that sensitive data in my diagrams, but otherwise this could have become a bad surprise…

I hope that in case of a direct update of the extension, which is now supported with 2.0.1, such config settings are respected and taken over, if the older Macro was configured accordingly?

When using the PlantUML server, the rendered image didn’t fit its box / into the page and was cut off to the right. Using my own GraphViz which was also used previously, the image fits fine and is scaled down just fine in case the browser window is resized.

Performance feels quite good.

Just as a side note: Why are you implementing a new version for a Macro which you think noone uses? And how did you get the impression that it’s not used - because noone had questions about it for a while? Maybe it just worked. (It did for me, at least - wasn’t the fastest, but cached the images, so performance was ok.)

@GOhrner

no it’s not supported yet, that’s more work to do to create an automation migration… You coud create a jira issue but not sure I’ll fix it anytime soon. Maybe a warning in the doc could be added for now.

Note that the plantuml server doesn’t store any data at all so that limits the risks.

ok interesting to know.

@GOhrner

Just as a side note: Why are you implementing a new version for a Macro which you think noone uses?

I implemented it to start using it on xwiki.org. See URL Architecture (XWiki.org)

@GOhrner

And how did you get the impression that it’s not used - because noone had questions about it for a while? Maybe it just worked. (It did for me, at least - wasn’t the fastest, but cached the images, so performance was ok.)

Yeah… was just a feeling. It wasn’t even a recommended extension. Let me change that now.

[vmassol]

@GOhrner

Performance feels quite good.

cool to know. Besides this you should now have all the new diagram types and new features added over the years by PlantUML too

What's new ?

[GOhrner]

@vmassol

I implemented it to start using it on xwiki.org. See URL Architecture (XWiki.org)

Looks nice.

I used it to document our internal IT infrastructure - which boxes do we use and which services are running where and depend on what other services?

However my diagram is by far not as colourful as yours.

[tmortagne]

@GOhrner

He is cheating, it’s just a plantuml theme

[GOhrner]

Oh, didn’t know about these. Looks nice!

However, if I try this myself in Xwiki, I just get a Syntax Error at the !theme directive… Mh, never mind…

[tmortagne]

@GOhrner

However, if I try this myself in Xwiki, I just get a Syntax Error at the !theme directive… Mh, never mind…

You can see how it’s used in the example on URL Architecture (XWiki.org).

[GOhrner]

Yes, thanks - that where I already tried to copy how to do it, but somehow failed…

In theory, I should only add the !theme row, shouldn’t I?

[vmassol]

@GOhrner

In theory, I should only add the !theme row, shouldn’t I?

Yes.

Maybe your plantuml server is too old or maybe your local graphviz install is oldish too?

[GOhrner]

Probably, that was my assumption.

I use a local GraphViz installation, no PlantUML server, the system is a plain Debian Stable. So I’ll just wait for Debian “Bullseye” to be released and perform another attempt afterwards.

[tmortagne]

@GOhrner

I use a local GraphViz installation, no PlantUML server, the system is a plain Debian Stable. So I’ll just wait for Debian “Bullseye” to be released and perform another attempt afterwards.

xwiki.org system is a Debian Buster (and use the version of GraphViz provided by Buster from what I understood) so I doubt your problem comes from this.
