Info

After going to http://hostname:port/mum/administration and publishing widgetsto the catalog, you may notice a widget named ’null’ instead of the Chart widget.As a workaround, do the following steps:1. In the catalog, go to Home → Upload Widget → iWidget URL and create a newwidget.2. Type the URL of the Chart widget, for example http://hostname:port/mum/chart/Charts.xml3. Update the details of the Chart widget an save it.4. Remove the null widget.Chart widget can display only pure numeric feed dataCurrently, the Chart widget can interpret and display only pure numeric feed datathat does not contain any special characters such as commas, currency symbols,and underscores. For example, the following two pieces of data will not work:100,000 or $100.00. If the feed data does contain non-numeric characters, the chartwill not display the data correctly, and you will get an error message saying thatnumeric data cannot be found.Note: For data in XLS or comma-separated value (CSV) format, note that theheader row and first item in each row can contain non-numeric data, for example:Vegetables,Y2005,Y2006,Y2007,Y2008Potato,19,18,20,57Onion,6,7,6,19Carrot,10,11,12,33Cabbage,9,9,6,24Total,44,45,44,133Chart widget may not display language-specific characters on Y axisWhen configuring the names of the X and Y axes of a chart, if you specify specialfont characters, for example double-byte characters, the characters may not displayproperly on the Y axis.Special characters cause chart data to display incorrectly in Chart widgetAfter configuring the Chart widget with a caption or subcaption that containsspecial characters such as ’&’, ’+’, ’″’, ’’ and ’?’, the caption and subcaptionmay not display properly in the chart, and the chart data may be wrong. As aworkaround, avoid using special characters in the caption and subcaption.Chart widget cannot resolve local URLs properlyWhen using the Chart widget, if you attempt to use a local resource for the data,and that local resource has a URL that begins with http://, users will get an errorwhen trying to access the Lotus Mashups main page using an HTTP protocol. Alocal resource means that it is hosted on the same sever as Lotus Mashups. Forexample, the resource can be a feed that is uploaded to the catalog, and the catalogis installed on the same server as Lotus Mashups. A sample URL may look like thefollowing:http://hostname:port/mashuphub/client/plugin/generate/entryid/12/pluginid/18As a workaround, view the feed details in catalog, right-click the feed URL, andcopy it as a link. This changes the HTTP to HTTPS in the feed URL. For example,the URL above would become the following:20 IBM Mashup Center: V1.1
https://hostname:port/mashuphub/client/plugin/generate/entryid/12/pluginid/18Then configure the chart’s data source with this URL.The ’km’ and ’mi’ strings in OpenStreetMap widget do not get localizedWhen working with certain non-English locales such as Simplified Chinese orTraditional Chinese, after you drag the OpenStreetMap widget onto the page, youmay notice that the ’km’ and ’mi’ strings do not get localized and display inEnglish.City and country names in OpenStreetMap widget do not get localized based onbrowser settingsAfter configuring your browser to a certain locale, you may notice that certain cityand country names that display on the OpenStreetMap widget do not getlocalized properly. In fact, they may display in multiple languages.Moving Sametime widget causes user to have to log in againOccasionally, moving the Sametime widget from one location on a mashup page toanother while logged in will cause the Sametime session to be discontinued. Thiswill not happen if you do not move the Sametime widget or if the page is in viewmode. This issue seems to occur more frequently when using the column theme.Multiple users cannot log into multiple Sametime widgets on a single pageIf your mashup page contains multiple Sametime widgets, when you log into onewidget and start a session, all the other Sametime widgets on the page will sharethe same session. You cannot log into any of the other widgets as a new user.Titles of hidden widgets may not get truncatedAfter moving certain widgets to the hidden widgets corral, you may notice that thewidget name does not get truncated to fit into the title box but instead crosses overthe boundary of the box. As a workaround, save the page and then reload orrefresh it.Large widgets move behind hidden widgets corral after being dragged from apageAfter resizing certain widgets to make them larger, and then attempting to dragthem into the hidden widgets corral, you may notice that the widgets move behindthe corral window instead of being added to the corral as a hidden widget. As aworkaround, do not drag the widget but instead click Hide from the contextualmenu.Resizing widgets can be difficult when using column page themeWhen working with widgets using a column page theme, you may find it difficultto resize widgets. The recommended workaround is to move your mouse slowlyand smoothly between the widget borders so that you can catch the widget resizehandler and effectively resize the widget.Data Editor widget produces error when processing large amount of feed dataKnown issues and workarounds in Lotus Mashups 21
