With loop use formState property to get rid of below exception. <t:loop source="keys" value="key" formState ="none"> <t:select model="value" encoder="value" value="key" formState="none"/> </t:loop>
Hope it will solve your issue.

Could you give me a hand with that? This is my Java code: private Map<Filter, GenericSelectModel<? extends Filter>> fieldMap; @Property private Filter key; public Set<Filter> getKeys() { return fieldMap.keySet(); } public GenericSelectModel<? extends Filter> getValue(){ return fieldMap.get(key); } where fieldMap is being initialized in @SetupRender with subtypes of Filter interface and base on Filter type I choose genericSelectModel for it. tml code: <t:loop source="keys" value="key"> <t:select model="value" encoder="value" value="key" formState="none"/> </t:loop> I am getting following exception: Caused by: org.apache.tapestry5.ioc.util.UnknownValueException: Could not find a coercion from type java.lang.String to type zeepp.fieldfilter.Filter. at org.apache.tapestry5.ioc.internal.services.TypeCoercerImpl.findOrCreateCoercion(TypeCoercerImpl.java:276) at org.apache.tapestry5.ioc.internal.services.TypeCoercerImpl.access$000(TypeCoercerImpl.java:38) at org.apache.tapestry5.ioc.internal.services.TypeCoercerImpl$TargetCoercion.getCoercion(TypeCoercerImpl.java:94) at org.apache.tapestry5.ioc.internal.services.TypeCoercerImpl$TargetCoercion.coerce(TypeCoercerImpl.java:71) at org.apache.tapestry5.ioc.internal.services.TypeCoercerImpl.coerce(TypeCoercerImpl.java:147) at $TypeCoercer_289900c49f8.coerce(Unknown Source) at org.apache.tapestry5.internal.services.TypeCoercedValueEncoderFactory$1.toValue(TypeCoercedValueEncoderFactory.java:45) at org.apache.tapestry5.corelib.components.Loop.restoreStateFromStoredClientValue(Loop.java:470) at org.apache.tapestry5.corelib.components.Loop.access$500(Loop.java:64) at org.apache.tapestry5.corelib.components.Loop$RestoreStateFromStoredClientValue.execute(Loop.java:185) at org.apache.tapestry5.corelib.components.Loop$RestoreStateFromStoredClientValue.execute(Loop.java:174) at org.apache.tapestry5.corelib.components.Form.executeStoredActions(Form.java:661) Thanks! -- View this message in context: http://tapestry.1045711.n5.nabble.com/Coercion-exception-in-loop-for-Map-tp5717072.html Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
