I have a small app with 5 elements. The tab slider is bring in xml data with weather information on each tab. It loads correctly initially, however, once I select an item, the tabs at the bottom will disappear.

I tried changing heights and views with now luck. One of the heights I changed was on the text element in the tab element, but it just cut off the xml data.

Has anyone encountered this before? I saw a post (http://forum.openlaszlo.org/showthread.php?t=4774) that had the same problem, but the fix was only for 1 xml feed.

(files are attached - screenshot, xml feeds, and lzx code).

Have you tried changing the height of the canvas? If you don't put a height attribute, it will resize to whatever size it needs to fit the view.

yes, I tried changing the height of the canvas, for some reason the tab element just seems to stop.

I can't reproduce that issue (at least using the latest trunk).

Wow, that's strange. Perhaps I should update my version? I downloaded the openlaszlo-4.1.1.war (dev kit). Do you have the nightly version?

Thanks for the screenshot.

Are you using a full version? What type of OpenLazlo install awere you successful on?

I have the dev kit on tomcat 5.5, using windows XP.

That worked for me as well. The only difference between the version you posted, and the original I provided was how the data was included. Does this mean I am referencing the xml portions wrong?

original:
<dataset name="rssdata" src="forecastrss.xml" request="true" type="http" />
<dataset name="rssdata2" src="forecastrssMont.xml" request="true" type="http" />
<dataset name="rssdata3" src="forecastrssVan.xml" request="true" type="http" />
<dataset name="rssdata4" src="forecastrssHalifax.xml" request="true" type="http" />
<dataset name="rssdata5" src="forecastrssCal.xml" request="true" type="http" />

Ok, I've found the reason:
At an early stage, the "<tabslider>" tries to calculate its required bounds. But at that time, all "<tabelement>"s aren't set visible, because the data wasn't loaded yet (any data-bound "<view>" remains invisible until the data arrives). May you file a bug-report at JIRA to help to fix that bug, thanks!

In the meantime, you've got two possibilities:
1) either set "visibility='visible'" on your "<tabelement>"s (this overrides the data-bound <-> visible logic)
2) or set the complete datapath on the inner view
